The Sun









         The sun is the main source of heat and light as forms of energy

         on earth. Nothing is more important to us on Earth than

         the Sun. Without the Sun's heat and light, the Earth would be

         a lifeless ball of ice-coated rock. The Sun warms our seas, stirs
         our atmosphere, generates our weather patterns, and

         gives energy to the growing green plants that provide the food

         and oxygen for life on Earth.
