| Term | Definition |
| infrared radiation. | a form of energy with wavelengths that are longer than red light. (long wavelengths) |
| visible light | the colors that are visible to see. (red, orange, yellow, green, blue, indigo, purple...) |
| ultraviolet radiation | has wavelengths that are eshorter then violet light. |
| greenhouse effect | the process by which gases hold heat in the air |
| thermometer | a tool the measures air temperature |
| heat transfer | the 3 ways of heat transfer are radiation, conduction, and convection. |
| radiation | energy coming from the sun, direct transfer of energy by electromagnetic waves. the heat from the sun or a campfire travels directly to us as infrared radiation. |
| conduction | the direct transfer of heat from one substance to another substance that it is touching |
| convection | the transfer of heat by the movement |
| anemometer | a tool used to measure wind speed |
| wind-chill factor | the increased cooling that a wind can cause |
| local winds | the uneven heating of Earths surface within a small area |
| land breeze | the flow of air from land to a body of water |
| monsoons | sea and land breezes over a large region that change direction with the seasons |
| sea breeze | The flow of air from water to land |
| globel winds | winds that blow steadily from specific directions over long distances |
| coriolis effect | the way Earth's rotation makes winds curve |
| major globel wind belts | trade winds, the prevailing westerlies, and the polar easterlies |
| latitude | the distance from the equator, measured in degrees |
| evaporation | the process by which water molecules in liquid escape into the air as water vapor |
| humidity | a measure of the amount of water vapor in the air |
| relative humidity | the percentage of water vapor in the air compared to the maximum amount the air could hold |
| psychrometer | a tool to measure relative humidity |
