| Term | Definition |
|---|---|
| Atmosphere | the envelope of gases surrounding the earth or another planet: |
| Stratosphere | the layer of the earth's atmosphere above the troposphere |
| Troposphere | the lowest region of the atmosphere, extending from the earth's surface to a height of about 3.7–6.2 mile |
| Thermosphere | the region of the atmosphere above the mesosphere |
| Air pressure | Atmospheric pressure is the force exerted on a surface by the weight of air above that surface in the atmosphere of Earth |
| radiation | the emission of energy as electromagnetic waves or as moving subatomic particles |
| thermal conduction | Heat conduction (or thermal conduction) is the transfer of internal energy by the heat of the sun, |
| convection | the movement caused within a fluid by the tendency of hotter and less dense material to rise, and colder, denser material to sink under the influence of gravity, which y results in transfer of heat. |
| Global warminghttp://sstk.biz/images/smredx.png | a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect |
| Greenhouse effect | The trapping of the suns warmth |
| Wind | the natural movement of the air. in the form of a current of air blowing from a particular direction |
| Coriolis effect | an effect whereby a mass moving in a rotating system experiences a force acting perpendicular to the direction of motion and to the axis of rotation |
| Westerlies | in a westward position or direction: |
| Trade winds | a wind blowing steadily toward the equator from the northeast in the northern hemisphere or the southeast in the southern hemisphere |
| Polar easterlies | are the dry, cold winds from the high-pressure areas of the polar highs at the north and south poles towards low-pressure areas within the Westerlies at high latitudes |
| Jet stream | a narrow, variable band of very strong, predominantly westerly air currents encircling the globe several miles above the earth |
| Air pollution | Air pollution is the introduction of harmful materials into the Earth's atmosphere |
| Acid precipitation | is a rain or any other form of precipitation that is unusually acidic |
