| Question | Answer |
|---|---|
| Air pressure | the measure of the force with which air molecules push on the surface |
| altitude | elevation (height) above sea level |
| Troposphere | lowest layer or earth atmospheric 0-17 km above Earths surface site of |
| Stratosphere | 2 layer of atmosphere extends fro 10 to 30 miles up location of ozone |
| Thermosphere | The fourth layer of the atmosphere in which tempature increases as altitude increases |
| Exosphere | The outer layer of the thermosphere extending outward into space. |
| Atmosphere Gases | Nitrogen makes up 78% 21% oxygen and remainning 1% is carbon dioxide water vapor and other gasses |
| Nitrogen (N2) | most abundunt gas in the atmosphere ( 78%) |
| Oxygen (O2) | Gas that makes up 21% of the air in Earth"s atmosphere.It passes into the blood stream at the lungs and travels to all body cells |
| Carbon Dioxide (C02) | a green house gas:that absorbs and radiates heat |
| Trace Gas | gasses such as hydrogen, Helium ,Carbon dioxide and argon that exist in very small quantities in the atmosphere gasses that make up less 1% of Earth atmosphere |
| Water Vapor | water in the form of a gas |
| Fossil Fuels | A natural substance formed from the buried remains of ancient organisms be used as a source of energy |
| Greenhouse gasses | gasses in Earth"s atmosphere that trap heat near the surface |
| water cycle | The continuous process by which water moves form Earth surface to the atmosphere and back |
| Evaporation | the change of a substance from a liquid to a gas |
| Condensation | the change from gas to liquid |
| Precipitation | any form of water that falls from clouds and reaches Earth surface ( rain or snow or hail or sleet or mist ) |
| Transpiration | evaporation of water from the leaves of a plant |
| Crystallization | the process by which a substance becomes a solid sort of like freezing |
| Surface Runoff | water that flows over land that reaches lakes, river, or ther aareas |
| Groundwater flow | water that is flowing beneath Earth"s surface |
| Dew | water that has condensed on a cool surface overnight from water vapor in the air |
| Frost | ice formed when water vapor changes directly into ice crystals |
| Ozone (O3) | part of Earth's upper atmosphere it protects people by absorbing harmful rays from the sun |
| Greenhouse effect | a warming of Earth"s surface and air above it .it is caused by gasses in the air that trap energy from the sun. |
| Mesosphere | middle layer or the atmosphere is 51-85 km coldest layer this is where meters burn up |
