Weather Part 1 Vocab
| Term | Definition |
|---|---|
| Air Pressure | The measure of the force with which air molecules push on a surface |
| Altitude | Elevation above sea level |
| Troposphere | Lowest layer of Earth's atmospheric: o-17 km above Earth's surface, site of weather, organisms, contains most atmospheric water vapor. |
| Stratosphere | 2nd layer of atmosphere; extends from 10 to 30 miles up; location of ozone layer; absorbs 95% of Ultraviolet radiation; temperature i creases with altitude increase. |
| Thermosphere | The fourth layer of the atmosphere, in which temperature increases as altitude increases. |
| Exosphere | The outer layer of the thermosphere, extending outward into space. |
| Atmospheric Gases | Nitrogen makes up 78%, 21% oxygen, and remaining 1% is carbon dioxide, water vaper and other gases. |
| Nitrogen(N2) | Most abundant gas in the atmosphere 78% |
| Oxygen(O2) | Gas that makes up 21% of the air in Earth's atmosphere. It passes into the bloodstream at the lungs and travels to all body cells. |
| Carbon Dioxide(CO2) | A greenhouse gas; a gas that absorbs and radiates heat. |
| Trace Gases | Gases such as hydrogen, helium, carbon dioxide and argon that exist in very small quantities in he atmosphere; gasses that make up less than 1% of Earth's atmosphere |
| Water Vapor | Water in the form of a gas |
| Fossil Fuels | A natural substance formed from the buried remains of ancient organisms that can be used as a source of energy |
| Greenhouse Gases | gasses in Earth's atmosphere that trap heat near the surface |
| Water Cycle | The continuous process by which water moves from Earth's surface to the atmosphere and back |
| Evaporation | The change of a substance from a liquid to a gas |
| Condensation | The change from a gas to a liquid |
| Precipitation | Any form of water that falls from clouds and reaches Earth's 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 becoma a solid, sort of like freezing. |
| Surface Runoff | Water that flows over land until it reaches lakes,rivers, or other areas. |
| 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 the Earth's upper atmosphere; it protects people by absorbing harmful rays from the sun. |
| Greenhouse Effect | A warning of Earth's surface and the air above it. It is caused by gases in the air that trap energy from the sun |
| Mesosphere | Middle layers of atmosphere; 51-85 km; coldest layer; this is where meteors burn up |
