Earth

media type="custom" key="4534336" width="518" height="116" As my project I chose earth (Blue Planet). Earth is the 3rd planet from the sun. Earth is the only known planet to support life form. Like humans, cats, dogs, birds and lots of others. Earth is the 5th biggest planet and has a diameter of about 12800km. Earth has a population of over 6.783 billion (updated 9th September). Earth got its name (Blue Planet) because the earth is more than 70 percent water. Its the only planet not to be named after a roman god. Average temperature is around 22 degrees Celsius but global warming its only getting warmer. If the earth was any closer than 1496BB* km the water would boil away and the earths temperature average would get a lot hotter and if the earth was any further the water would freeze over and the earths temperature average would get a lot cooler. A earth day goes for 23.56 hours and every 4 years we have a leap year to take up for the 4 minutes missing. Earth has 4 main colours blue for water, green for green land (grass, Rain forest etc.) Brown, (desert dirt) and white for ice. Most of the land is green but the further away from the equator the darker it gets till it gets to white. The equator is a line through the earth (it not really there like you cant see it but it goes right through the middle) and that is where the weather is hottest. Earth has an atmosphere a invisible sort of blanket round earth that keeps the air in. But the more green house gases we make its getting thinker witch traps the green house gases and the heat cant get out witch makes global warming. Earth has 1 moon. Rotates around the earth. Nothing to special about it. Round grey and got shallow holes in it from meteors. For more on the moon visit http://bse8hmissiontomars.wikispaces.com/Moon
