| Term | Definition |
|---|
| radiation | the transfer of energy as electromagnetic waves. |
| thermal conduction | the transfer of energy as heat through a material. |
| troposphere | the lowest layer of the atmosphere, in wich temperature decreases at a constant rate as altitude increases. |
| stratosphere | the layer of the atmosphere that is above the troposphere and in wich temperate increases as altitude increases. |
| mesosphere | the strong, lower part of the mentle between the asthenosphere and the outer core also the layer of the atmosphere between the stratosphere and the thermospere and in which temperature deceases as altitude increases. |
| thermosphere | the upper most layer of the atmosphere, in which temperature increases as altitude increases. |
| ozone layer | it's in the stratoshere protects life on Earth by absorbing harmful ultravidet radiation. |
| atmosphere | mixture of gases that surounds a planet or moon. |
| westerlies | prevailing winds that blow from west to east between 30 and 60 latitude in both hemisphere. |
| trade winds | prevailing winds that blow northeast from 30 north latitude to the equator and that blow southeast from 30 south tatitude. |
| jet streams | a narrow belt of strong winds that blow in the upper troposhere. |
| air pollution | the contamamination of the atmosphere by the introduction pollutants from human and natural sources. |
| acid precipitation | rain, sleet, or snowthat contains a high concentration acids. |
| acdidification | it's a process where acid precipitation causes the acidity of soil to increase. |
| doldroms | area around the equator with very little wind. |
| pessure belts | bands of high pressure and low pressure found about every 30 latitude. it separate convection cells. |
| convection cells | air travels in large ciruler patterns. |
| coriolis effect | the apparent curving of the path of moving object from an otherwise straight path due to the earht's rotation. |
| radiation balance | in going energy and out going energy being balance on earth. |
| auroras | ions that radiate energy as shimmering light. |
| ionosphere | it's where gas particles in thermosphere become electrically charges. they are called ions. |
| air pressure | the measure of the force with which air molecules push on a surface. |
| convection | the transfer of thermal energy by the circulation or movement of liquid or gas. |
| greenhouse effect | the warming of the surfaceabd lower atmosphere of the earth that occurs when water vopor, carbon dioxide, and other absorb and reradiate thermal energy. |
| global warming | a gradual increase in average global temperature. |
| wind | the movement in air pressure. |
| polar easterlies | prevailing winds that blow from east to west between 60 and 90 latitude in hemispheres. |
| water vapor | invisible gas |
