Energy in Earth Syst
Unit 10
| Term | Definition |
|---|---|
| Earth systems | is all of the matter , energy , and processes within Earth's boundary. |
| geosphere | is the mostly solid, rocky part of Earth. |
| hydrosphere | is the part of the Earth that is liquid water. |
| cryosphere | is made up of all of the frozen water on Earth. |
| atmosphere | is mostly made of invisible gases that surround Earth. |
| biosphere | is made up of living things and areas of Earth. |
| energy budget | is a way to keep track of energy transfers into and out of the Earth system. |
| air pressure | is the measure of the force with which air molecules push on an area of a surface. |
| thermosphere | is the uppermost layer of the atmosphere. |
| mesosphere | is between the thermosphere and stratosphere. |
| stratosphere | is between the mesosphere and troposphere. |
| troposphere | is the lowest layer of the atmosphere. |
| ozone layer | is an area in the stratosphere, 15 km to 40 km above Earth surface, where ozone is highly concentrated. |
| greenhouse effect | is the process by which gases in the atmosphere , such as water vapor and carbon dioxide, absorb and give off infrared radiation. |
| temperature | is a measure of the average kinetic energy of particles. |
| thermal energy | is the total kinetic energy of particles. |
| thermal expansion | the increase in volume that result from an increase in temperature. |
| heat | is the energy that is transferred between objects that are at difference temperatures. |
| radiation | is the transfer of energy as electromagnetic waves. |
| convection | is the transfer of energy due to the movement of matter. |
| conduction | is the transfer of energy from one object to another object through direct conitact. |
| wind | the movement of air caused by difference in air pressure . |
| Coriolis effect | the apparent curving of the path of a moving object from an otherwise straight path due to Earth's rotation . |
| global wind | these wind systems occur at or near Earth's surface. |
| jet streams | are narrow belts of high speed winds that blow from west to eat, between 7 km and 16 km above Earth's surface. |
| local wind | are movements of air over short distances. |
| ocean current | the oceans contain stemlike movements of water. |
| surface current | ocean currents that occur at or near the surface of the ocean caused by wind. |
| deep current | movements of ocean water far below the surface . |
| convection current | is a movement of water that result from density differences. |
| upwelling | the warm surface is then replaced by cold nutrient rich water from the deep ocean in a process. |
