Earth


Earth is the third planet from the sun.  It is a rocky planet that is the only one we know to have life and liquid water.  The Earth rotates every twenty-four hours.  This means that when the Earth is facing the sun it is daytime and when it is not it is night.  The Earth is tilted on an axis.  This means that when the Earth is tilted toward the sun it is Summer and when it is tilted away from the sun it is Winter.  Places near the equator are always warm and the North and South Pole are always cold.
