|---|---|
| Atmosphere | -whole layer of air that surrounds the earth |
| Altitude | -distance above sea level |
| Density | -amount of mass in a given volume in a given substance |
| Cycles | -a process that repeats over and over |
| Radiation | -energy that travels across distances in the form of different types of rays |
| Conduction | -the transfer of heat energy from one substance to the other by direct object |
| Troposphere | -layer of atmosphere nearest to earth's surface |
| Stratosphere | -layer above troposphere -clear and dry contains "ozone" |
| Mesosphere | -thin air -layer above stratosphere |
| Thermosphere | -top layer -less dense -becomes outer space when altitude rises |
| Ultraviolet radiation | -has more energy than the light we can see -sound waves are too low for us to hear |
| Infrared radiation | -has less energy than visible light -warms materials that absorb it |
| Ozone | -made of three atoms of oxygen |
| Greenhouse effect | -when the gases absorb and emit infrared radiation which keeps energy in the earths system for a while |
| Greenhouse gases | -Carbon dioxide, methane, water vapor, nutrios oxide, etc. |
| Air pollution | -smoke and other harmful material that are added to the air |
| Particulates | -tiny particles/droplets that are mixed with the air |
