| Question | Answer |
|---|---|
| The two most abundant compounds in air are the gases carbon dioxide and?? | Water Vapor. |
| What holds the gases of the atmosphere near Earth's surface?? | Gravity. |
| The pressure exerted on a surface by the atmosphere is called?? | Atmospheric Pressure. |
| Because the pull of gravity is not as strong at higher altitudes, the air molecules there are farther apart and exert?? | Less Pressure. |
| One effect of air pollution is destruction of?? | The Ozone Layer. |
| As they become heated, molecules in a substance?? | Move faster. |
| What phase does ice change into when it absorbs energy?? | Liquid. |
| When liquid water absorbs energy, it changes to?? | A gas. |
| The name for heat energy that is absorbed or released during a phase change is?? | Latent Heat. |
| The name for the process in which water vapor changes back into a liquid is?? | Condensation. |
| Through what process does most water enter the atmosphere?? | Evaporation. |
| What must happen in order for a cloud droplet to fall as precipitation?? | It must increse in size. |
| The process in which freezing or condensation nuclei are introduced into a cloud to cause rain is called?? | Cloud Seeding. |
| Atmosphere?? | A mixture of gases, primarily nitrogen, oxygen, and argon, that surrounds Earth. |
| Troposphere?? | The lowest layer of the atmosphere, in which temperature drops at a constant rate as altitude increases. (Only that one.) |
| Stratosphere?? | The layer of the atmosphere in which temperature increases as altitude increases. (Only that one.) |
| Mesosphere?? | The coldest layer of the atmosphere in which temperature decreases as altitude increases. |
| Thermosphere?? | The uppermost layer of the atmosphere. (Only that one.) |
| Stratus Clouds?? | Clouds with a flat base forming at very low altitudes. |
| Cumulus Clouds?? | Billowy, low-altitude clouds. |
| Cirrus Clouds?? | Feathery clouds composed of ice crystals. |
| Humidity?? | Water Vapor in the atmosphere. |
| Dew Point?? | The temperature at which condensation equals evaporation. |
| Absolute Humidity?? | The mass of water vapor contained in a given volume of air. |
| Relative Humidity?? | The ratio of water vapor in a unit of air relative to the amount of water the air can hold at that temperature. |
| Rain?? | Liquid Precipitation. |
| Drizzle?? | Rain consisting of drops smaller than 0.5 mm in diameter. |
| Snow?? | Precipitation consisting of ice particles. |
| Hail?? | Solid Precipitation in the form of lumps of ice. |
| It says what does each letter represent and please label the following diagram with these choices. So here I go! Cloud?? | E. |
| Condensation Level?? | D. |
| Cold moist air?? | A. |
| Warm Air?? | C. |
| Solar Energy?? | B. |
