| Composition of the atmosphere | 78% nitrogen, 21% oxygen, 0-4%water vapor, also argon, carbon dioxide, ozone, methane |
| Troposphere | lowest part, where weather occurs, temperature decreases with altitude. |
| Stratosphere | 2nd lowest, ozone, temperature increases because ozone absorbs uv radiation |
| Mesophere | 2nd highest, meteorites, temperature decreases with altitude |
| Thermosphere | highest (for our needs) temperature increases with altitude (first to absorb uv radiation) |
| jet stream | fast moving wind at the tropopause that helps move the warm air from the equator to the mid latitudes. |
| Ocean currents & climate | Winds warm and cool surface currents...move and bring warmer or colder climate to different parts of the Earth. |
| coriolis effect | because of Earth's rotation, winds don't move in a straight line. In Northern Hemisphere moves clockwise, southern hemisphere moves counterclockwise. |
| causes of El Nino | warmer water in the Pacific, no upwelling |
| effects of El Nino | flooding in Peru and Californina, lack of fishing in Pacific, droughts (inc Ohio) |
