| troposphere | layer of earths atmosphere closest to the ground,contains clouds,smog,weather and 75%of atmoshpheric gases |
| ionosphere | layer of erths atmosphere where ions and electrons absorb AM radio waver during the dayand reflect them back at night |
| ozone layer | a latyer of the stratosphere with a high consentration of ozone,obsorbs ultraviolet rays |
| ultraviolet radiation | a type of energy that comes to earth from the sun,can damage skin,cause skin cancer,and other health problems |
| chlorofluorocarbons | a group of chemicals used as refirerants and aerisol spray propellants,thes chemicals detroy the ozone layer |
| Coriolis effect | the effect of earths rotation on the movement of air masses |
| jet stream | narrow wind belts occuring near the top of the troposphere |
| sea breeze | wind blowing from sea to land during the day when the sun warms the land faster and cool air from above the water forces the warm air above the land to rise |
| land breeze | wind blowing from land to sea at night,because the land cools faster and cool air ove the land moves out to the sea. |
| radiation | the transfer of energy through matter or space by electromagnetic waver |
| conduction | the transfer of hat that occurs when mollcules collide. |
| convection | the transfer of heat by flow of heated material. |
| hydrosphere | all the water that occurs on earths surface. |
| water cycle | continuous movement of ater through evaporation,condensation,and precipitation. |
