Transcription: The Earth is one of nine planets that travel around the Sun in the solar system. Of these planets, the Earth is the third nearest the Sun. It is the only planet known to support life. About five billion years ago, a cloud of gas and dust began to condense into a solid mass, the young Earth. At first, this mass was very cold, but later it was melted by radioactivity. Heavy metals collected at the center and rocks floated near the surface. After millions of years, the rocks formed a hard crust and the oceans and the atmosphere appeared.
