Earth System
Unit 10
| Term | Definition |
|---|---|
| Earth system | the study of the interconnected components of our environment—the atmosphere, hydrosphere, lithosphere, cryosphere, and biosphere—and how they interact to produce an integrated whole. |
| geosphere | made up of all rock and rocky materials on the surface and under the surface of Earth. |
| cryospere | Earth's ice in all its forms. |
| atmosphere | A mixture of gases that surrounds a planet,moon,or other celestial body. |
| bioshpere | The part of Earth where life exists |
| energy budget | The net flow of energy into and out of a system. |
| air pressure | The measure of force with which air molecules push on a surface. |
| thermospere | The uppermost layer in which temperature increases as altitude increases |
| mesospere | The layer of the atmosphere between the stratospere and the thermosphere and in which temperature decreases as altitude increases |
| stratospere | The layer of the atmospheree that lies between the troposphere and the mesospere and in which temperature increases as altitude increases and contains the ozone layer. |
| tresospere | |
| ozone layer | The layer of the atmosphere at an altitude of 15 to 40 km in which ozone absorbs ultraviolet solar radiation. |
| greenhouse effect | The warming of the surface and lower atmospere of Earth that occurs when water vapor, carbon dioxide, and other glasses absorb and reradiate energy. |
| temperature | A measure of how hot or cold something is specifically a measure of the average kinetic energy of the particles in an object. |
| thermal energy | The total kinetic energy of a substance's atoms. |
| thermal expansion | An increase in the size of a substance in response to an increase in the temperature of the substance. |
| heat | The energy transferred between objects that are at different temperatures. |
| 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 |
| conduction | The transfer of energy as heat through a material |
| 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 worldwide. |
| jet stream | A narrow band of strong winds that blow in the upper troposphere |
| local wind | The movement of air over short distances |
| ocean current | A movement of ocean water that follows a regular pattern |
| surface current | A horizontal movement of ocean water that is caused by wind and that occurs at or near the ocean's surface. |
| deep current | a stream like current movement of ocean water far below the surface. |
| convection current | any movement of matter that results from differences in density ;may be vertical |
| upwelling | the movement of deep cold and nutrient- rich water to the surface. |
