earth systems
unit 10
| Term | Definition |
|---|---|
| Earth system | All of the nonliving things,living things, and processes that make up the planet earth,including the solid earth, the hydrosphere, that atmosphere, and the biosphere |
| geosphere | the mostly solid, rocky part of earth extends from the center of the core to the surface of the crust. |
| hydrosphere | the portion of earth that is mad of water. |
| cryrosphere | one of Earth's spheres where water is in a solid form, including snow cover, floating ice, glaciers, ice caps, ice sheets, and frozen ground permafrost. |
| atmosphere | a mixture of gases that surrounds the planet, moon, or other celestial body. |
| biosphere | the part of earth where life exists includes all of the living organisms on earth |
| energy budget | the net flow of energy into and out of a system |
| air pressure | the measure of force with air molecules push on a surface |
| theremosphere | the uppermost layer of the atmosphere in Wich tempature tempature increases |
| mesophere | the strong lower part of mantele between the asthenosphere ant the outer core |
| stratosphere | the layer of the atmosphere that lies between the troposphere and the mesosophere and in witch temperature increases as altitude increases contains ozone layer. |
| troposphere | the lowest layer of the atmosphere in Wich in witch temperature drops at a constant rate as altitude increases the part of the atmosphere where weather conditions exist |
| ozone layer | the layer of the atmosphere at an altitude of 15 to 40km in witch ozone absorbs ultraviolet solar radiation. |
| greenhouse effect | the warming of the surface and the lower atmosphere of earth that occurs when water vapor carbon dioxide and other gases absorb and reradiated energy |
| temperature | a measure of how hot or cold something is specifically a measure of the avarege kinetic energy of the particles in a object |
| thermal energy | an increase in the size of a substance in response to an increase in the tempature substance. |
| thermal expansion | the energy transfered between objects that are a diffrent tempature |
| heat | the energy transfeered between objects that are at different temputures. |
| radiation | the transfer of energy as electromagnetic waves |
| convection | the movement of matter due to differences in density the transfer of energy due to the movement of matter |
| coduction | the transfer of energy s heat through a metirial |
| wind | the movement of air caused by differences in air pressure |
| Coriolis effect | the curving of the path of a moving object from an otherwise straight path due to Earth's rotation |
| global wind | the movement of air over Earth's surface in patterns that are world wide |
| jet stream | A narrow band o strong winds that blow in the upper troposphere |
| local wind | the movement of air over short distances occurs in specific areas as a result of certain geographical feature |
| ocean current | a movement of ocean water that follows a regular pattern |
| surface current | a movement of ocean water that follows a regular pattern |
| deep current | a stream like movement of ocean water far below the surface |
| convection current | an movement of matter that resaults from difrences in density may be vertical circular cycle |
| upwelling | the movement of deep cold and nutrient rich water to the surface |
