Earth In Space
What makes Earth so darn special?????
What you need to know about Earth
Earth is in space and rotates around the sun, and the moon rotates around the Earth and sun. The Earth has tides because of the gravitational pull from the Earth and the moon. One revolution is a year on earth and one rotation is a day. The Earth has an axis that acts as a pole through the north and south poles of the Earth. Earth is a very important planet. The moon has a sixth the gravity of Earth. Some people say the moon is made of cheese because of the craters. But in reality meteors hit the surface and make huge craters in the moon. (The man in the moon is not really a man it just looks that way because of craters). Earth has an amtosphere made of hydrogen, carbon dioxide, nitrogen and oxygen (which is crucial for human life). Earth is also lucky enough to have formed in such a place to where its water is usable (not frozen or otherwise hidden). Life requires water, so Earth is the perfect place for living organisms to thrive. Finally, Earth formed the perfect distance from the sun...its not too hot and not too cold, so we can all really enjoy the weather! :-)
