| atmosphere | thin layer of air that forms a protective cover around the planet. |
| troposphere | layer of Earth's atmosphere that is closest to the ground. Where clouds and weather occur. |
| ionosphere | layer of electrically charged particles in the thermosphere that absorb AM radio waves during the day and reflect them back at night. |
| ozone layer | layer of the stratosphere with a high concentration of ozone: absorbs most of the Sun's harmful ultraviolet radiation. |
| ultraviolet radiation | type of energy that comes to Earth from the Sun, can damage skin and cause cancer, and is mostly absorbed by the ozone layer. |
| chlorofluorocarbon | group of chemical compounds used in refrigerators, air conditioners, foam packaging, and aerosol sprays and may enter the atmosphere and destroy ozone. |
| radiation | energy that is transferred by waves. |
| conduction | transfer of energy by collision of atoms in a material. |
| convection | transfer of heat that occurs when particles move between objects or areas of different temperature. |
| hydrosphere | all the water on Earth's surface. |
| condensation | process in which water vapor changes to a liquid. |
| Coriolis effect | the rotation of the Earth causes moving air and water to appear to turn to the right north of the equator and to the left south of the equator. |
| jet stream | narrow belts of strong wind that blow near the top of the troposphere, |
| sea breeze | movement of air from sea to land during the day when cooler air from above the water moves over the land, focing the heated, less dense air above the land to rise. |
| land breeze | movement of air toward the water from the land. |
