|---|---|
| atmosphere | Earths air, which is made up of a thin layer of gasses,solids and liquids |
| chlorofluorocarbons | group of chemical compounds used in refrigerators, air conditioners,foam packaging, and aerosol sprays |
| conduction | transfer of energy by collisions between the atoms in a material |
| condensation | process in which water vapor changes to a liquid |
| convection | transfer of heat that occurs when particles move between objects or areas of different temperature |
| Coriolis effect | causes moving air and water to turn left in the southern hemisphere and turn right in the northern hemisphere due to earths rotation |
| hydrosphere | all the water on the earths surface |
| ionosphere | layer of electrically charged particles in the Thermosphere that absorbs am radio waves during the day and reflects them back at night |
| jet stream | narrow belt of strong winds that blows near the top of the troposphere |
| land breeze | movement of air from land to sea at night, created when cool, dense air from the land forces worm air up over the sea |
| ozone layer | layer of the stratosphere with a high concentration of ozone, absorbs most of the suns harmful ultraviolet radiation |
| radiation | energy that is transferred by waves. |
| sea breeze | movement of air from sea to land during the day when cooler air from above the water moves over the land ,forcing the heated,less dense air above the land to rise |
| troposphere | layer of earths atmosphere that is closest to the ground,contains 99 percent of the water vapor and 75 percent of the atmospheric gases, and is where clouds and weather occur |
| ultraviolet radiation | a type of energy that comes to earth from the sun, can damage skin and cause cancer,and is mostly absorbed by the ozone layer |
