weather part 1 Vocab
| Term | Definition |
|---|---|
| Mesosphere | middle layer of atmosphere 51-85 km. The coldest layer this is where meteors burn up. |
| Air Pressure | the measure of the force with which air molecules push on a surface. |
| altitude | elevation ( height) above sea level |
| Troposphere | lowest layer of earth's atmosphere 0-17 km above Earth's surface> site of weather, organisms ,contains most atmospheric water vapor |
| Stratosphere | 2nd layer of atmosphere. extends from 10 to 30 miles up. The location of ozone layer absorbs 95% of Ultraviolet radiation. tempretures increases with altitude increase. |
| Mesosphere | middle layer of atmosphere 51-85 km. The coldest layer this is where meteors burn up. |
| Thermosphere | the fourth layer of the atmosphere, in which temperture increases as altitude increase |
| Air Pressure | the measure of the force with which air molecules push on a surface. |
| Exosphere | the outer layer of the thermosphere, extending outward into space. |
| altitude | elevation ( height) above sea level |
| Atmospheric gases | nitrogen makes up 78% 21% oxygen and remaining 1% is carbon dioxide, water vapor and other gases. |
| Troposphere | lowest layer of earth's atmosphere 0-17 km above Earth's surface> site of weather, organisms ,contains most atmospheric water vapor |
| Nitrogen | most audant |
| Stratosphere | 2nd layer of atmosphere. extends from 10 to 30 miles up. The location of ozone layer absorbs 95% of Ultraviolet radiation. tempretures increases with altitude increase. |
| Thermosphere | the fourth layer of the atmosphere, in which temperture increases as altitude increase |
| Exosphere | the outer layer of the thermosphere, extending outward into space. |
| Atmospheric gases | nitrogen makes up 78% 21% oxygen and remaining 1% is carbon dioxide, water vapor and other gases. |
| Nitrogen | most abundant gas in the atmosphere(78%) |
| Oxygen 02 | gas that makes up 21% of the air in earths atmosphere. It passes into the bloodstream at the lungs and travels to all body cells. |
| Carbon dioxide C02 | A green house gas. a gas that radiates and absorbs heat |
| Trace Gases | gasses such as hydrogen, helium, carbon dioxide and argon that exsists in very small quantaties in the the atmosphere. gasses that make up less than 1 percent of earths atmosphere. |
| water Vapor | water in the foem of a gas |
| Fossil Fuels | natural substance formed from the buried remains of acient organisms that can be used as a source of energy |
| Greenhouse gasses | Gasses in earths atmosphere that trap heat near the surface |
| Water cycle | the continues process by which water moves from the earth's surface to the atmosphere and back. |
| Evaporation | the change of a substance from liquid to gas |
| Condisation | change from gas to liquid |
| precipitation | any form of water that falls from the clouds and reaches earths surface(rain, snow , hail, sleet, mist) |
| transpiratation | evaporation of water from the leaves of a plant |
| crystallization | the process of which the substance becomes a solid, sort of like freezing |
| surface runoff | water that flows over land until it reaches lakes, rivers, or other areas |
