A geyser is a natural fountain of hot water or steam. It erupts from time to time from an opening in the ground. Geysers erupt when underground water is heated by hot, volcanic rocks just below the surface. This heat comes from inside the Earth and is called geothermal energy.When you are feeling very active, someone may tell you that you have a lot of energy. Energy is the ability to do something. It takes many different forms. Fuel contains energy: it is used to make vehicles work. Food also contains energy: it allows you to walk or run. The Sun gives off heat and light.

Plants use the light energy from sunlight during photosynthesis. This is their way of making food by combining carbon dioxide with water. Sunlight makes the chemical reaction happen.
