2. Solar energy      is the energy of the sun.

3. Radiation-     how the Sun’s energy moves through space, as  radiation strikes the Earth’s surface, it changes into heat.

4. hydrologic or water cycle-     endless process in which water evaporates from oceans and lakes, condenses into clouds and returns to the Earth as precipitation.

5. Solar energy       heats the water and drives the water cycle

6. Three states of water-     solid, liquid, and gas
