Intro:We all need sunlight and warmth for life. If the earth was too close, it would be too hot for living things and if it were too far, it would be too cold. Also, water is a key element for all living things, and the earth has plenty. crust forms the surface of the earth. It is a thin layer of rock. Life on earth is either on the crust or in the water, which covers 70 percent of it. Below the crust is hot rock and below this is a ball of metal at the center. earth is the fifth largest planet and the third planet from the sun. Its diameter is 8,000 miles long. earth is about 93 million miles from the sun. The atmosphere of Earth contains enough oxygen to sustain life. This can be compared to with other planets such as Mars, where it consists of only carbon dioxide.
