1/3

The Planet Earth was formed approximately 4.5 billion years ago. So far, our very own PlanetEarth is the only planet that harbors life. From the ancient years, there were many theoriesregarding the shape of the earth and the many myths associated with it as well. Today, our PlanetEarth faces threat due to human intervention and activities. Have you ever wondered how thisname was derived? Or what is the approximate distance of the Planet Earth from the sun? Let us

now unearth some interesting facts about Planet Earth and know what makes this Planet really sospecial to us.

Planet Earth Facts:

The Earth is not actually round in shape; in fact it is geoid. This simply means that therounded shape has a slight bulge towards the equator.

So what causes this geoid shape? This happens solely because the rotation of the Earthwhich causes the bulge around the equator.

Earth is the third planet from the Sun. This is also the fifth largest planet in the entiresolar system.

Did you know this interesting fact about Planet Earth that it is the only planet whosename has not been derived from the Roman or Greek mythology? The name hasoriginated from the 8th century Anglo Saxon word- Erda. This means ground or soil.

Heres another Planet Earth fact - oceans cover around 70% of the Earths surface. Theway the water vapor is distributed through the atmosphere results in the weather that isexperienced on Planet Earth.

The Planet Earth takes approximately 23 hours, 56 minutes and 4.091 seconds to rotatearound its axis. Therefore, on an average, the Planet Earth takes around 24 hours tocomplete a full rotation.

Our Planet Earth is divided into various layers that comprise the surface of the Earth. TheEarths crust varies in terms of thickness. The inn er core and the crust of the Planet Earthare solid in nature. Where as the outer core and the mantle layers are semi fluid in nature.The Earths crust is relatively thinner under the ocean floors and thicker in other areas.

One can note that towards the surface, the air consists of around 78 percent nitrogen with21 percent oxygen. This air also contains 1 percent of other ingredients. This is the kindof atmosphere that greatly affects the weather of Planet Earth. It also helps to shield usfrom harmful radiations that may emanate from the Sun.

Gravity is what keeps all living beings alive and prevents them from falling off the PlanetEarth as it completes its rotation.

Another interesting fact about the Planet Earth is that the gravitational pull between theEarth and the moon is what causes the tides in the oceans and seas. This is also the reasonwhy only one side of the Moon always faces us; the period of rotation is equivalent to thetime it takes to orbit the Earth.

The Planet Earth moves around 18.5 miles in a second in the orbit around the sun. Ittravels around 150 mikes per second in its rotation, which is around the center of theMilky Way galaxy.

Explorer 6 first photographed our Planet Earth from space in the year 1959. Yuri Gagarinwas the first human to be able to view Planet Earth from space in the year 1961.

Our Planet Earths hydrosphere consists mainly of water and when one speaks aboutwater, it means oceans. This includes all the seas, lakes and even water bodies that flow

underground. This abundance of water is what sets the Planet Earth apart from other planets.

The Earth is one such planet that provides an atmosphere, which helps to sustain life. Ithas the requisite amount of water and other conditions that are so very essential for anyform of life to exist.

Our Planet Earth is only slightly larger than Venus. But due to the dense nickel core,which is present in the center of the Earth, we can see that Venus has only 80 percent themass of Earth.

The four seasons that we experience on Planet Earth are a result of the Earths axis ofrotation. This is tilted at an angle, which is more than 23 degrees.

Did you know that the field of gravity is not the same in all areas over the surface of theEarth? This is probably why you feel slightly heavier in certain areas.

Our planet is truly very interesting, indeed. While 70% of the planet is covered with water, themost advanced life form on Earth is found on its land mass. That life form is responsible for thelife threatening damage, it does to the existence of life on Earth itself. Any guesses on who I'm

taking about? Yes, it's us, the mighty bipedal animals that rule this kingdom and slowly draggingit to ruin. Anyway, take a look at some facts that truly make this blue planet unique. Read moreon earth science .

Interesting Facts About Earth, the Planet

Earth is the only planet in the solar system with plate tectonics. That means that while thecore is liquid the crust floats on the core of the planet.

Around 47% of the Earth's crust consists of oxygen. Earth is a big magnet, with poles at the top and bottom of the planet. It takes the Earth 23 hours, 56 minutes and 4 seconds to rotate on its axis. That means a

day is not exactly 24 hours. A year on Earth is 365.2564 days and not 365 days. The extra .2564 days is why leap

years were created. Earth is the only planet in the Solar System to have water in all three states of matter:

(solid) ice, (liquid) sea, rain, etc. and (gas) clouds. It is believed that millions of years ago, a day on Earth was approximately 20 hours long,

so after a million years, a day on Earth will be 27 hours long. The Earth will appear as the brightest of the 8 planets, if viewed from a specific distance

in space. This is because the water bodies on Earth reflect large amount of sunlight.

These were some facts about the planet, let's take a look at what truly makes this planet special.Before that you may want to take a look at planet Earth facts .

Odd Facts About Earth, the Planet

El Azizia (Libya) is the hottest place on Earth, and Vostok (Antarctica) is the coldest. Rain has never been recorded in some parts of the Atacama Desert in Chile. Venice in Italy is gradually sinking in the water. It is built on 118 sea islets joined by 400

bridges.

A California bristlecone pine name 'Methuselah' is the oldest living tree. It is almost 4600years old.

The Antarctic Notothenia fish can't freeze in the icy waters of its habitat as it has a protein in its blood that acts like antifreeze and prevents freezing.

There is one chicken for every human being on earth. Humans grow by about 0.3 inches every night in sleep, but shrink back to normal during

the day. Bones are five times stronger than steel.

So these were some other small facts about Earth or rather life on Earth. Some of these aren't odd but apparently if you ate too many carrots, you'd turn orange. Now, I'm not making this up, I

actually came across this when I was surfing the internet! I don't think it's true though. I guessone will have to eat a whole lot of carrots! You can take a look some more interesting facts here,

Amazing Facts About Earth Facts About the Moon Amazing Facts About the Universe

The Earth is the only planet with life on it. No surprise there! Everyone knows that yet for everyhundredth human who thinks that it's not their responsibility to care for this fragile planet, thereare only a handful of those who spend their time and energy conserving this beautiful world. Toconclude, I hope that one day when someone else from another planet is writing on interesting

facts about Earth, they don't mention this. "Earth the only planet with life in the milky way. Themost progressive life form of which were the Humans, who ironically brought about extinctionon the blue planet."
