DESTINATION PLANET EARTH
Planet Earth is what we live on. The Earth is round like most planets. We only have one, lonely Moon that orbits around us. About 30% of the Earth's surface is made up of land, the other 70% is covered in water. Unfortunately, 2.5% of that water is clean. STOP POLLUTING THE EARTH!! The Earth is estimated to be 4.5 billion years old. It travels through space at 660,000 miles per hour. The oldest rocks in the world, the so-called St. Peter and St. Paul stones in the Atlantic Ocean, are 4 billion years old. The Earth weighs 6,588,000,000,000,000,000,000,000 tons. The earth rotates on its axis more slowly in March than in September.
