| Infrared radiation is a type of | Electromagnetic energy and heat |
| Which gas is the greatest amount in the atmosphere? | Nitrogen |
| Define weather | Weather - the condition of the atmosphere at a given time and place. |
| Define atmosphere | Atmosphere - the envelope of gases that surrounds Earth. |
| Define water vapor | Water in the form of a gas |
| Define density | The ratio of mass of a substance to its volume |
| Define air pressure | Pressure caused by the weight of a colum of air pushing down on air |
| Define altitude | Elevstion above sea level |
| Define ozone | A form of oxegen that has 3 atoms in each molocule |
| Define radiation | The transfer of heat by electromagnetic waves |
| Define infrared radiation | Electromagnetic waves with wavelengths that are longer than visible light |
| Define visible light | Includes all colors of the rainbow, Visible light is a wave that can be detected (seen) by human eyes (also know as the visible spectrum) |
| Define ultraviolet radiation | Electromagnetic aves with wavelengths that are shorter than visible light. Can cause sunburn |

| Define heat | The transfer of thermal energy from one object to the other |
| Define convection | The teansfer of thermal energy by the movement of fluid |
| Define conduction | The transfer of thermal energy from one particle to the other |
| Define convection currents | The movement of a fluid caused by differences in tempeatures. Convection currents transfer heat from one part of a fluid to the other |
