The student should read the material and locate on the letter matrix, the energy sources that are in bold italics. Define nuclear energy. The sun is a renewable energy source. List examples of the possible natural uses of the sun. Wind can be used in many passive ways.
Water covers approximately three-fourths of the Earth's surface.
List examples of the forms of energy that can be realized from the movement of water. Thermal, radiant, electrical, mechanical, chemical and atomic energy. Nuclear energy is heat created by fission which is the splitting of atoms or by fusion where two atoms are fused together. Cooling is accomplished by the ability of the wind to remove or relocate heat from an object, combustion air is required for fire, and pumping water by windmills. Hydroelectric dams, turbines designed to take advantage of the Mississippi River and the Gulf Stream, tidal power, ocean thermal gradients, cooling with water by exposing it to clear night sky, thermal inertia, thermal storage by water, and watering of plants.
