    I Have a few of them, Smile

    The hottest temperature recorded on Earth was in El Azizia, Libya on September 13, 1922. The temperature reached 136 degrees Fahrenheit (57.8 Celsius). The second hottest temperature recorded was in Death Valley, CA, which measured 134 degrees F.

    About 400 billion gallons of water is used everyday worldwide.

    The coldest temperature recorded on Earth was in Vostok, Antarctica . The temperature reached -129 degrees F (-89 C) on July 23, 1983.

    The wettest place on earth is in Llorro, Colombia, which receives about 40 feet (13 meters) of rainfall annually.

    I hope you like my awsome facts, LOL! Smile

    Since the world is almost water I'll post facts about that! If you take a contaner or test tube filled with hydrogen, then put a glow stick in the test tube, you will hear a loud pop. What is that? You just made water, less then a mL, but still water. No one does this because it is really expencive.

    Fairy Bridge: Fairy Bridge (Xian Ren Qiao) is a meander natural bridge carved through limestone karst by the Buliu River, a tributary of the Hongshui River. It is located about 90 km northeast of Bose in northwestern Guangxi Province, China. Raft tours of the Buliu River that float under this bridge are a popular tourist attraction for the area. Estimates from photoanalysis indicate that Fairy Bridge has a span of about 295 feet, which if confirmed by accurate measurement in the field would make it the longest span in the world. The estimated height of the opening is 210 feet.

    facts for Niagara falls! cyclops
    Niagara Falls were formed as a result of glaciers receding at the end of the Wisconsin glaciation and water from the newly-formed Great Lakes, which together created a path through the Niagara Escarpment en route to the Atlantic Ocean.
    Their length of brink is 1060 feet while their height is 176 feet. Niagara Falls are one of the most powerful waterfalls in North America.
    3,160 tons of water flows over the falls every second. This accounts for 75,750 gallons of water per second over the American and Bridal Veil Falls and 681,750 gallons per second over the Horseshoe Falls.
    The Niagara Falls is truly one of the most powerful water falls in the North Americas

    ere are many things about Earth that most people do not know. It is actually a very interesting planet. A lot of people think that the Earth is round, but it is really pear-shaped. The top is pushed in and the bottom bulges out! The circumference, or distance around the Earth at the equator (or the fattest part of the "pear"), is 24,901.55 miles.

    The Earth is always moving. It spins or rotates while traveling in a big circle around the Sun. Its orbit or path around the Sun is 583,400,000 miles long. Earth travels along this path at 66,000 mile-per-hour. The Earth rotates at 1,000 miles-per-hour. That is pretty fast!

    Here are some other strange facts about Earth. There is a lot of water in the Earth's atmosphere. In fact, there is enough water to cover the entire surface of the Earth with one inch of water! The atmosphere that holds all that water rises 250 miles above the Earth's surface. Our planet is located in the perfect place for our need for water. If it was any closer or farther away from the Sun, all that water would either boil away or freeze.

    Earth's moon is also unique. It is one of the biggest in our solar system. When you look at the moon, you always see the same side. Many people think that Earth has a second moon. This is really Asteroid 3753, but strangely enough, it orbits the Earth.

    As you can see, there is a lot more to the Earth than you thought!Plate tectonics keep the planet comfortable
    Earth is the only planet in the Solar System with plate tectonics. The outer crust of the Earth is broken up into regions known as tectonic plates. These are floating on top of the magma interior of the Earth and can move against one another. When two plates collide, one plate can go underneath another.This process is very important. When microscopic plants in the ocean die, they fall to the bottom of the ocean. Over long periods of time, the remnants of this life, rich in carbon, are carried back into the interior of the Earth and recycled. This pulls carbon out of the atmosphere, which makes sure we don’t get a runaway greenhouse effect, like what happened on Venus.
    Without the plate tectonics, there’d be no way to recycle this carbon, and the Earth would overheat.Earth is mostly iron, oxygen and silicon
    If you could separate the Earth out into piles of material, you’d get 32.1 % iron, 30.1% oxygen, 15.1% silicon, and 13.9% magnesium. Of course, most of this iron is actually down at the core of the Earth. If you could actually get down and sample the core, it would be 88% iron. 47% of the Earth’s crust consists of oxygen.The atmosphere is thickest within the first 50 km or so, but it actually reaches out to about 10,000 km above the surface of the planet. This outermost layer of the atmosphere is called the exosphere, and starts about 500 km above the surface of the Earth. As we said, it goes all the way up to 10,000 km above the surface. At this point, free-moving particles can actually escape the pull of Earth’s gravity, and be blown away by the Sun’s solar wind.
    But this high atmosphere is extremely thin. The bulk of the Earth’s atmosphere is down near the Earth itself. In fact, 75% of the Earth’s atmosphere is contained within the first 11 km above the planet’s surfaceThe Earth is like a great big magnet, with poles at the top and bottom of the planet, near to the actual geographic poles. This magnetic field extends from the surface of the Earth out thousands of kilometers - a region called the magnetosphere.
    Be grateful for the magnetosphere. Without it particles from the Sun’s solar wind would hit the Earth directly, exposing the surface of the planet to significant amounts of radiation. Instead, the magnetosphere channels the solar wind around the Earth, protecting us from harm.
    Scientists think that the magnetic field is generated by the molten outer core of the Earth, where heat creates convection motions of conducting materials. This generates electric currents that create the magnetic fieldA year on Earth isn’t 365 days
    It’s actually 365.2564 days. It’s this extra .2564 days that creates the need for leap years. That’s why we tack on an extra day in February every year divisible by 4 - 2004, 2008, etc - unless it’s divisible by 100 (1900, 2100, etc)… unless it’s divisible by 400 (1600, 2000, etc).Earth doesn’t take 24 hours to rotate on its axis
    It’s actually 23 hours, 56 minutes and 4 seconds. This is the amount of time it takes for the Earth to completely rotate around its axis; astronomers call this a sidereal day. Now wait a second, that means a day is 4 minutes shorter than we think it is. You’d think that time would add up, day by day, and within a few months, day would be night, and night would be day.
    Remember that the Earth orbits around the Sun. Every day, the Sun moves compared to the background stars by about 1° - about the size of the Moon in the sky. And so, if you add up that little motion from the Sun that we see because the Earth is orbiting around it, as well as the rotation on its axis, you get a total of 24 hours. Now that sounds like the day we know.

    Earth has 1 moon and 2 co-orbital satellites
    As you’re probably aware, Earth has 1 moon (The Moon). But did you know there are 2 additional asteroids locked into a co-orbital orbits with Earth? They’re called 3753 Cruithne and 2002 AA29. We won’t go into too much detail about the Moon, I’m sure you’ve heard all about it.
    3753 Cruithne is 5 km across, and sometimes called Earth’s second moon. It doesn’t actually orbit the Earth, but has a synchronized orbit with our home planet. It has an orbit that makes it look like it’s following the Earth in orbit, but it’s actually following its own, distinct path around the Sun.
    2002 AA29 is only 60 meters across, and makes a horseshoe orbit around the Earth that brings it close to the planet every 95 years. In about 600 years, it will appear to circle Earth in a quasi-satellite orbit. Scientists have suggested that it might make a good target for a space exploration mission.

    Facts About Earth

    Earth is best defined as the only planet in our solar system that is known to support life. It is the third planet in the solar system, in terms of ascending distance from the Sun. Earth has all the ingredients needed for life, in the form of air, water, and so on. The fifth largest planet in the solar system, the planet is composed of three layers - a core, a mantle and an outer crust. A fun trivia about Earth is that though the planet is named 'Earth' only 29 percent of its surface is actually comprises of land (earth), while the rest is made up of water. Read on to explore some more interesting and fun facts about Earth.

    Interesting & Fun Facts about Earth

    * Earth is the only planet in the Solar System to have water in all its three states of matter: solid (ice), liquid (sea, rain, etc.) and gas (clouds).
    * Earth is almost five billion years old, although life has only existed on the planet for the last 150 to 200 million years. This means that life has been present on the planet for only 5%-10% of its lifetime.
    * Earth and Mercury are the two densest planets in the Solar System.
    * The length of time it takes for Earth to orbit the Sun is 365 and a quarter days. To make up this extra quarter, which isn't counted at the end of a year, we have an extra day every four years i.e. on 29th February.
    * Earth is gradually slowing down. Every few years, an extra second is added to make up for lost time. Millions of years ago, a day on Earth will have been 20 hours long. It is believed that, after a few million years, a day on Earth will be 27 hours long.
    * The centre of the Earth i.e. its core is molten. This means that it is liquid rock, which sometimes erupts onto the surface through volcanic eruptions. This core is 7,500° C hotter than the surface of Sun!
    * Earth is the only planet in the Solar System not to be named after a mythical God.
    * Despite being called Earth, only 29% of the surface is actually 'earth' (land). The rest of the planet's surface (71%) is made up of water.
    * From a distance in space, Earth would seem to be the brightest of the 8 planets. This is because large amount of sunlight is reflected by the water on the planet.
    * Earth is the only planet in the Solar System known to be geologically active, with earthquakes and volcanoes forming the landscape, replenishing carbon dioxide into the atmosphere and erasing impact craters from meteors.
    * Earth's average distance from the Sun is 149,600,000 km (92,960,000 miles)
    * Earth has a diameter of 12,760 km and mass of about 5.972 x 1024 kg
    * Earth is the fifth largest planet in the Solar System.
    * Earth has only one satellite, the Moon. Moon is the second brightest object in the sky, as seen from the planet.
    * Earth's atmosphere is composed mainly of nitrogen (77%), oxygen (21%), argon (0.93%), and carbon dioxide (0.03%).
    * El Azizia (Libya) is the hottest place on Earth, while Vostok (Antarctica) is the coldest.
    * Earth travels at an orbital speed of around 108,000 km (67,000 miles) an hour.
    * Earth, along with Mercury, is densest planet in the Solar System.
    * Earth is home to millions of species, including humans.
    * The average distance between Earth and Moon is 238,857 miles (384,403.1 km).

    The Niagara Falls are voluminous waterfalls on the Niagara River, straddling the international border between the Canadian province of Ontario and the U.S. state of New York. The falls are 17 miles (27 km) north-northwest of Buffalo, New York and 75 miles (120 km) south-southeast of Toronto, Ontario, between the twin cities of Niagara Falls, Ontario, and Niagara Falls, New York.

    Niagara Falls is composed of two major sections separated by Goat Island: Horseshoe Falls, the majority of which lies on the Canadian side of the border, and American Falls on the American side. The smaller Bridal Veil Falls are also located on the American side, separated from the main falls by Luna Island.

    Niagara Falls were formed when glaciers receded at the end of the Wisconsin glaciation (the last ice age), and water from the newly-formed Great Lakes carved a path through the Niagara Escarpment en route to the Atlantic Ocean. While not exceptionally high, the Niagara Falls are very wide. More than six million cubic feet (168,000 m³) of water falls over the crest line every minute in high flow,[1] and almost 4 million cubic feet (110,000 m³) on average. It is the most powerful waterfall in North America.[2]

    The Niagara Falls are renowned both for their beauty and as a valuable source of hydroelectric power. Managing the balance between recreational, commercial, and industrial uses has been a challenge for the stewards of the falls since the 1800.

    Niagara Falls, as viewed from Canada, with the American and Bridal Veil falls on the left, and Horseshoe Falls on the right.

    Niagara Falls is divided into the Horseshoe Falls and the American Falls. The Horseshoe Falls drop about 173 feet (53 m), the height of the American Falls varies between 70-100 feet (21 m) because of the presence of giant boulders at its base. The larger Horseshoe Falls are about 2,600 feet (792 m) wide, while the American Falls are 1,060 feet (323 m) wide.

    The volume of water approaching the falls during peak flow season may sometimes be as much as 202,000 cubic feet per second (5,720 m³/s).[3] Since the flow is a direct function of the Lake Erie water elevation, it typically peaks in late spring or early summer. During the summer months, 100,000 cubic feet per second (2,832 m³/s) of water actually traverses the Falls, some 90% of which goes over the Horseshoe Falls, while the balance is diverted to hydroelectric facilities. This is accomplished by employing a weir with movable gates upstream from the Horseshoe Falls. The Falls flow is further halved at night, and during the low tourist season in the winter, remains a flat 50,000 cubic feet per second (1,416 m³/s). Water diversion is regulated by the 1950 Niagara Treaty and is administered by the International Niagara Board of Control (IJC).[4] Viewpoints on the American shore generally are astride or behind the falls. The falls face directly toward the Canadian shore. Thus, the most complete views of Niagara Falls are available from the Canadian side of the river.

    There are differing theories as to the origin of the name of the falls. According to Iroquoian scholar Bruce Trigger, "Niagara" is derived from the name given to a branch of the locally residing native Neutral Confederacy, who are described as being called the "Niagagarega" people on several late 17th century French maps of the area.[8]

    A number of figures have been suggested as first circulating an eyewitness description of Niagara Falls. Frenchman Samuel de Champlain visited the area as early as 1604 during his exploration of Canada, and members of his party reported to him the spectacular waterfalls, which he described in his journals. Finnish-Swedish naturalist Pehr Kalm explored the area in the early 1700s and wrote of the experience. The consensus honoree is Belgian Father Louis Hennepin, who observed and described the Falls in 1677, earlier than Kalm, after traveling with explorer René Robert Cavelier, Sieur de la Salle, thus bringing the Falls to the attention of Europeans. Further complicating matters, there is credible evidence that French Jesuit Reverend Paul Ragueneau visited the Falls some 35 years before Hennepin's visit, while working among the Huron First Nation in Canada. Jean de Brébeuf also may have visited the Falls, while spending time with the Neutral Nation.[9]

    During the 18th century, tourism became popular, and by mid-century, it was the area's main industry. Napoleon Bonaparte's brother Jérôme visited with his bride in the early 19th century.[10] In 1837 during the Caroline affair a rebel supply ship, the Caroline, was burned and sent over the Falls. Demand for passage over the Niagara River led in 1848 to the building of a footbridge and then Charles Ellet's Niagara Suspension Bridge. This was supplanted by German-born John Augustus Roebling's Niagara Falls Suspension Bridge in 1855. After the American Civil War, the New York Central railroad publicized Niagara Falls as a focus of pleasure and honeymoon visits. With increased railroad traffic, in 1886, Leffert Buck replaced Roebling's wood and stone bridge with the predominantly steel bridge that still carries trains over the Niagara River today. The first steel archway bridge near the Falls was completed in 1897. Known today as the Whirlpool Rapids Bridge, it carries vehicles, trains, and pedestrians between Canada (through Canadian Customs Border Control) and the U.S.A. just below the Falls. In 1941 the Niagara Falls Bridge Commission completed the third current crossing in the immediate area of Niagara Falls with the Rainbow Bridge, carrying both pedestrian and vehicular traffic between the two countries and Canadian and U.S. customs for each country.

    After the First World War, tourism boomed again as automobiles made getting to the Falls much easier. The story of Niagara Falls in the 20th century is largely that of efforts to harness the energy of the Falls for hydroelectric power, and to control the development on both sides that threaten the area's natural beauty. study

    this is The water of Angel Falls lol! .....





    ...
    Sir Walter Raleigh described what was possibly a tepuy (table top mountain), and he is sometimes said to have discovered Angel Falls, but these claims are considered "far-fetched".[2] They were spotted in 1912 by the Venezuelan explorer Ernesto Sanchez La Cruz, but he did not publicize his discovery. They were not known to the outside world until American aviator Jimmie Angel[3] flew over them on 16 November 1933 on a flight while he was searching for a valuable ore bed.

    Returning on October 9 1937, Angel tried to land his Flamingo monoplane "El Rio Caroni" atop Auyan-tepui, but the plane was damaged when the wheels sunk into the marshy ground, and he and his three companions, including his wife Marie, were forced to descend the tepui on foot. It took them 11 days to make their way back to civilization, but news of their adventure spread, and the waterfall was named "Angel Falls" in his honor.
    Angel's plane

    Angel's plane remained on top of the tepuy for 33 years before being lifted out by helicopter. It was restored at the Aviation Museum in Maracay and now sits outdoors on the front of the airport at Ciudad Bolívar.

    The first recorded person to reach the river that feeds the falls was Latvian explorer Aleksandrs Laime, also known as Alejandro Laime to the native Pemon tribe. He made the ascent of Auyan-tepui in 1955. He also reached Angel's plane on the same trip, 18 years after the crash landing. He gave the river feeding the falls the name Gauja after a river in Latvia, but the Pemon-given name of the river, Kerep, is still widely used.

    Laime also was the first to clear a trail that leads from the Churun river to the base of the falls. On the way, there is a viewpoint commonly used to capture the falls in photographs. It is named "Mirador Laime" ("Laime's Viewpoint" in Spanish) in his honor. This trail is used now mostly for tourists, to lead them from the Isla Raton camp to the small clearing.

    The official height of the falls was determined by a National Geographic Society survey carried out by American journalist Ruth Robertson in 1949.[4]

    A book by Luke Dickinson, Angels Four, chronicles the first successful climb up the face of Auyantepui to the top of the falls.

    [edit] Tourism

    Angel Falls is one of Venezuela's top tourist attractions, but even today a trip to the falls is not a simple affair. The falls are located in an isolated jungle region of Venezuela, and a flight from Caracas or Ciudad Bolívar is required to reach Canaima camp, the starting point for river trips to the base of the falls.

    It is also possible to purchase a package that includes an aerial flyby of the falls. The falls cannot be seen on cloudy days, and there is no guarantee visitors will see them.

    River trips generally take place from June to December, when the rivers are deep enough for the wooden curiaras used by the Pemon Indian guides. During the dry season (December to March) there is less water than is seen in some photos, but it is also more likely that the top will not be clouded. study

    Interesting Facts About Earth

    There are many things about Earth that most people do not know. It is actually a very interesting planet. A lot of people think that the Earth is round, but it is really pear-shaped. The top is pushed in and the bottom bulges out! The circumference, or distance around the Earth at the equator (or the fattest part of the "pear"), is 24,901.55 miles.

    The Earth is always moving. It spins or rotates while traveling in a big circle around the Sun. Its orbit or path around the Sun is 583,400,000 miles long. Earth travels along this path at 66,000 mile-per-hour. The Earth rotates at 1,000 miles-per-hour. That is pretty fast!

    Here are some other strange facts about Earth. There is a lot of water in the Earth's atmosphere. In fact, there is enough water to cover the entire surface of the Earth with one inch of water! The atmosphere that holds all that water rises 250 miles above the Earth's surface. Our planet is located in the perfect place for our need for water. If it was any closer or farther away from the Sun, all that water would either boil away or freeze.

    Earth's moon is also unique. It is one of the biggest in our solar system. When you look at the moon, you always see the same side. Many people think that Earth has a second moon. This is really Asteroid 3753, but strangely enough, it orbits the Earth.

    As you can see, there is a lot more to the Earth than you thought!

    I have one! It is highly possible that in the future california will break apart from America and move over to the Canada area.

    That the sun's UltraViolet rays have three kinds of rays. and even if its cloudy the clouds wont have any effect.

    Emporer penguins can weigh up to 400 pounds and can be up to a meter tall.

    I hope i get the V flag and my chobot name is Mimo378.

    i just turned 13 YES.
    one more fact.

    carbon monoxide is a colorless oderless gas that has one hydrogen bond and three oxygen bonds. ok thats it so i really hope that i get the V flag and bye bye

    emos rock.

    Mount everest
    it is the tallest mountain in the world. mount everest is found in the Himalaya.The Sherpa name for mount evverest is "Chomolugma" which means "Godess mother of land".Mount everest was named after George Everest who was a 19th centuary geographer. The first two people to reach the summit are Tenzing Norgay and Edmund Hillary in May 29, 1953. Edmund was a beekeeper in New Zealand. Very Happy

    -Did you know that the gravity isnt the same all around the earth Twisted Evil
    -The coldest temperaure on earth was Vostok, Antarctica and it was -89 Degrees Celcius pale
    -Rocks can grow, but its a really boring process. A rock grows 1 milimeter every million years(Sorry if u mentioned it before)
    -The largest recorded Snowflake was 15 inches wide and 8 inches thick. It fell in Montana 1887 albino
    -Earth travels in space at 66,700 miles per hour.
    -The Earth has over 1,200,000 species of animals, 300,000 species of plants & 100,000 other species.

    SUN EXPLODING AAAH!!!!

    In 1.0000.000 years the the sun will explode!!!!
    AAAH!!!!!
    Or so it is belived so we still have hope!
    cheers

    I hope this Dosent happen though



    Interesting facts about Earth FigC_30

    affraid
    AAAAH!!!

    RUN FOR YOUR LIVES!!!!!

    bounce bounce bounce bounce bounce bounce bounce bounce


    Phew now that thats over here are some earth facts!

    Weird gravity:
    It turns out that in some places you will feel slightly heavier than others. A low spot can be seen just off the coast of India, while a relative high occurs in the South Pacific Ocean. The cause of these irregularities is unknown since present surface features do not appear dominant. NASA's GRACE twin satellites, launched in March 2002, are making detailed measurements of Earth's gravity field which will lead to discoveries about gravity and Earth's natural systems.

    Escaping atmosphere!!!

    Due to thermal energy, some of the molecules at the outer edge of the Earth's atmosphere have their velocity increased to the point where they can escape from the planet's gravity. This results in a slow but steady leakage of the atmosphere into space. Because unfixed hydrogen has a low molecular weight, it can achieve escape velocity more readily and it leaks into outer space at a greater rate.[61] For this reason, the Earth's current environment is oxidizing, rather than reducing, with consequences for the chemical nature of life which developed on the planet. The oxygen-rich atmosphere also preserves much of the surviving hydrogen by locking it up in water molecules.

    Earth is slowing down all the time?

    As a result of variation in gravitational forces due to the moon, the sun and other planets in the solar system, displacements of matter in different in different parts of the planets and other excitation mechanisms, the rotational speed of the Earth about it's axis varies in time. Recently, days have been getting shorter by hundredths of a second, which implies that the angular velocity of the Earth has been increasing. The factors causing this increasing in the Earth's rotational velocity have not been determined. The rotation data shows oscillations over several different timescales. The one with the largest variation is seasonal: Earth slows down in January and February.

    Van allen radiation belt thingy

    The Van Allen Radiation Belt is a torus of energetic charged particles (plasma) around Earth, held in place by Earth's magnetic field. Apollo astronauts who traveled to the moon spent very little time in the belts but probably have a slightly higher risk of cancer during their. NASA said that they deliberately timed Apollo launches, and used lunar transfer orbits that only skirted the edge of the belt over the equator to minimize the radiation. Besides, there have been nuclear tests in space that have caused artificial radiation belts. Starfish Prime, a high altitude nuclear test created an artificial radiation belt that damaged or destroyed as many as one third of the satellites in low earth orbit at the time.

    Moon dont go away!!!

    The reasons why have to do with tides and conservation of energy and angular momentum. Measurements have been collected now for over 25 years, and it is clear that the Moon's orbit is slowly growing larger and that the Moon is moving away from the Earth. The net result is that the Moon is receding from the Earth at about 4 centimeters a year. However, astronomers have predicted that when the Sun enters the red giant phase in around 5 billion years - during the red giant phase of the Sun - both Earth and Moon will be affected by the Sun's extended atmosphere and will aproach again. Then the Moon will swing ever closer to Earth until it reaches a point 11,470 miles (18,470 kilometers) above our planet, a point termed the Roche limit. The result: Moon will be torn to pieces and will be scattered to form a spectacular 23,000-mile-diameter (37,000-kilometer) Saturn-like ring of debris above Earth's equator.

    No Crying or Very sad

    The moon has a tidal effect on the atmosphere!

    The Moon has a tidal effect on the atmosphere as well as the oceans. Theory predicts stronger lunar pressure oscillations in the tropics but their amplitude rarely exceeds 100 microbars or 0.01 percent of the average surface pressure. Detection of such a tiny signal masked by much larger pressure variations associated with weather phenomena required the development of special statistical techniques and the accumulation of a long series of regular observations. It is common for atmospheric waves to grow in amplitude with height as the air becomes thinner. The lunar tide, however, remains weak compared to the solar tide in the upper atmosphere.

    The chandler wobble

    The Chandler wobble is a small variation in Earth's axis of rotation, discovered by American astronomer Seth Carlo Chandler in 1891. It amounts to 0.7 arcseconds over a period of 433 days. In other words, Earth's poles move in an irregular circle of 3 to 15 metres in diameter, in an oscillation. The cause is unknown. On 18 July 2000, the Jet Propulsion Laboratory announced that "the principal cause of the Chandler wobble is fluctuating pressure on the bottom of the ocean, caused by temperature and salinity changes and wind-driven changes in the circulation of the oceans. However, on janauary-february 2006 scientist noticed the Chandler wobble had stopped and there was a near six week period in which a significant pause occurred. This anomaly has been of great interest in gaining a better understanding, but it is not yet known if this has or will cause any catastraphic changes in the overall rotation axis of the planet.

    Electrical earth change

    Since 1917 scientists have known that the earth's surface is charged with negative electricity, but no one knew for sure what keeps it charged. In areas of fair weather, an electric current flows between the earth and the air in a direction which would tend to dissipate the charge. It is not much of a current: only about 1,500 amperes, not much more for the entire earth than flows in a few power lines. But the electricity taken from the earth must be restored somehow or the earth's electric charge would soon drain away. An obvious guess is that thunderstorms somehow restore the lost charge, but no one had proved it. Three years ago the institution borrowed airplanes from the Air Force and began to measure electrical stirring in the still air above active thunderheads. Sure enough, the instruments showed a current moving in the opposite direction to the current in fair-weather areas. The scientists figured that all the thunderstorm going on at one time generate a net current of about 1,500 amperes, just enough to balance the drain and keep the earth's charge constant.

    Dusty Earth

    According to space.com, about 30,000 tons of interplanetary dust reaches Earth's surface every year. Most asteroids roam around the Sun in a belt between Mars and Jupiter. The fragments of their collisions, and the dust, can be drawn toward the inner solar system and sometimes approach Earth. Dust and rocks moving fast in relation to Earth frequently slam into the atmosphere and burn up, generating shooting stars. Stuff moving more slowly relative to Earth can be captured by the planet's gravity and survive the plunge.

    Earths magnetic poles change places!!!

    The poles on the Earth have changed places - many times! We can tell this has happened because the magnetic moment of the rocks that make up the ocean floor have an alternating direction. Which direction they exhibit depends on which way the poles were oriented when the rocks were being formed at the mid-ocean ridge. During a reversal, which can take thousands of years, the magnetic poles start to wander away from the region around the spin poles, and eventually end up switched around. Sometimes this wandering is slow and steady, and other times it occurs in several jumps.

    That all folks!
    Wait noo!

    Awww i can't belive that you slept through all that!!!! Mad Mad Mad Mad Mad Mad Mad

    Interesting facts about Earth Andes-11

    The Andes Mountain range in South America is 4,525 miles long and ranks, as the world’s longest. Second Longest: The Rockies; Third: Himalayas; Fourth: The Great Dividing Range in Australia; Fifth: Trans-Antarctic Mountains. For every 980 feet you climb up a mountain, the temperature drops 3-1/2 degrees.

    Interesting facts about Earth Oblate10

    The Earth is, in fact, not really round. It is called an oblate spheroid meaning it’s slightly flattened on the top and bottom poles.

    Interesting facts about Earth Desert10

    Believe it or not, most of the Earth’s deserts are not composed entirely of sand. Much, about 85% of them, are rocks and gravel. The largest, the Sahara, fills about 1/3 of Africa (and it is growing constantly) which would nearly fill the continental United States.


    Interesting facts about Earth Earths10

    Many layers of atmosphere coat our planet including the mesosphere, ionosphere, exosphere, and the thermosphere, but it’s the troposphere, closest to the planet itself, that supports our lives and is, in fact, the thinnest at only about 10 miles high.
