| 2 | A form of energy, such as heat waves, visible light, and X-rays, that can radiate through empty space. | 
 
 
| 3 | The amount of heat energy needed to raise the temperature of one gram of pure water one Celsius degree | 
 
 
| 4 | A body of arid air that is low in humidly because it formed over a land area. | 
 
 
| 5 | A large body of air that has relatively uniform conditions of temperature and pressure. | 
 
 
| 6 | A body of air that is relatively moist because it formed over an ocean. | 
 
 
| 7 | Latent potential energy absorbed when a liquid vaporizes and released when a gas condenses. | 
 
 
| 8 | A high-pressure system that usually brings cool, clear weather as its winds rotate clockwise and away from the center. | 
 
 
| 9 | A weather system in which the atmospheric pressure is lower than surrounding areas. | 
 
 
| 10 | Latent potential energy absorbed when a solid melts and released when a liquid freezes. | 
 
 
| 11 | A measure of the average vibrational kinetic energy of a substance. |
