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. |
