Atmosphere/Water
| Term | Definition |
|---|---|
| Atmosphere | a “blanket” of gases that surrounds the Earth |
| Condensation | process by which water vapor changes to liquid water |
| Conduction | type of heat transfer from one material to another by direct physical contact |
| Convection | type of heat transfer where circular currents are formed in liquids or gases due to differences in density |
| Density | the amount of mass an object has in a given space |
| Evaporation | process by which liquid water turns to water vapor (gas) |
| Exosphere | area beyond our atmosphere; outer space |
| Groundwater | water that is held in rock layers under the surface of the Earth |
| Heat | a form of energy that moves from warmer areas to cooler areas |
| Ionosphere | a layer within the mesosphere and thermosphere that contains charged particles; where auroras occur |
| Mesopause | separates the mesosphere and thermosphere |
| Mesosphere | layer of the atmosphere where temperature decreases as altitude increases; coldest layer; meteors burn in this layers |
| Ozone Layer | layer in the stratosphere that protects us from harmful ultraviolet radiation |
| Permanent Gases | gases in the atmosphere that are always present in a fixed amount |
| Precipitation | process by which water falls from the atmosphere to Earth’s surface |
| Radiation | type of heat energy transfer where heat travels through empty space; an example is the Sun’s rays |
| Reflection | process by which the Sun’s rays reach the Earth’s atmosphere but are bounced back into space |
| Runoff | water flowing over the surface of the Earth |
| Solar Energy | radiant energy that travels from the Sun through empty space and reaches Earth |
| Stratopause | separates the stratosphere and mesosphere |
| Stratosphere | layer of the atmosphere that increases in temperature as altitude increases; where planes fly, contains the jet stream and ozone layer |
| Thermosphere | layer of the atmosphere where temperature rises with altitude; hottest layer; space shuttles orbit here |
| Trace Gases | atmospheric gases that are present in a tiny amount |
| Transpiration | process by which water evaporates from the leaves of plants |
| Tropopause | separates troposphere and stratosphere |
| Troposphere | thinnest layer of the atmosphere; where people live and weather occurs; temperature decreases with altitude; most dense layer |
| Variable Gases | gases in the atmosphere that change in their amount; an example is water vapor |
| Weather | the meteorological conditions such as temperature and precipitation in a particular location |
