| Term | Definition |
|---|---|
| earth system | its a group of connected parts of the earth that interact with one another |
| geosphere | the solid part of earth including rocks, soil, and land |
| hydrosphere | all the water on earth, including ocean, river, lakes, and groundwater. |
| cryosphere | its the frozen water on earth including glaciers, ice sheets, snow, and sea ice. |
| atmosphere | the layer of gases surrounding the earth. |
| biosphere | its the part of the earth where living organisms exist. |
| energy budget | the balance between the energy earth receives from the sun and the energy it releases back into space. |
| air pressure | its the force that the weight of air exerts on earths surface. |
| thermosphere | the layer of earths atmosphere with very high temperatures. |
| mesosphere | its the layer of earths atmosphere above the stratosphere where most meteors burn up. |
| stratosphere | its the layer of earths atmosphere above the troposphere that contains the ozone layer. |
| troposphere | the lowest layer of earths atmosphere where we live and where most weather occurs. |
| ozone layer | its the gas made of three oxygen atoms that help protect the earth from UV radiation |
| greenhouse effect | the process where gases in earths atmosphere trap heat from the sun keeping earth warm. |
| temperature | its the measurement of how hot or cold something is. |
| thermal energy | the total energy of the particles in a substance due to their motion. |
| thermal expansion | its the increase in size of a substance when its temperature increases |
| heat | the transfer of thermal energy from a warmer object to a cooler object. |
| radiation | its the transfer of energy from one place to another through waves or particles. |
| convection | the transfer of heat through the movement of a liquid or gas. |
| conduction | its the transfer of heat through direct contact between objects or particles. |
| wind | the movement of air from one place to another. |
| Coriolis effect | its the apparent deflection of moving air or water caused by earth rotation. |
| global wind | the large patterns of air movement around earth caused by difference in heating and earths rotation. |
| jet stream | its a narrow band of very strong winds high in the atmosphere that moves from west to east. |
| local wind | the winds that blow over a small area and is caused by local differences in temperature and air pressure. |
| ocean current | its a continuous movement of ocean water in a particular direction. |
| surface current | the movement of ocean water near the surface mainly caused by wind. |
| deep current | its the movement of deep ocean water caused mainly byndifferences in water temperature. |
| convection current | the circular movement of a fluid caused by warm material rising and cool material sinking. |
| Upwelling | its the movement of cold nutrient water from deep in the ocean up toward the surface. |
