|
Term
|
Definition
| A boundry that lies at the top of the troposphere in which the tempurature declines and acts like a transitional zone between the troposphere and the stratosphere. |

Term
|
Definition
| Decreased the amount of UV radiation that falls to Earth's surface. Majority of it lies in the stratosphere. |
|
|
Term
|
Definition
| Air pressure is extemely low, tempurature decreases with height. |
|
|
Term
|
Definition
| Uppermost layer of the atmosphere, with the lowest air pressure, temperature, and altitude. |
|
|
Term
|
Definition
| Measures the force per unit area produced by a column of air. Decreases with altitude, because the higher the altitude the fewer molecules are being pulled down by gravity. |
|
|
Term
|
Definition
| The ratio of water vapor a given volume of air contains to the maximum amount it could contain at a given temperature. |
|
|
Term
| Reasons for Season Change |
|
Definition
| Seasons change due to the varying angles the the suns beams hit the Earth throughout different parts of the year. This is because Earth spins on an axis. |
|
|
Term
|
Definition
| This circulation occurs when there is warm air closer to the ground so it rises up toward colder air and colder air falls toward the ground. This creats a cycle of warm air rising and cool air falling. |
|
|
Term
|
Definition
| Temporarily the conditions going on. |
|
|
Term
|
Definition
| The more permanent average of the tempurature. |
|
|
Term
|
Definition
| A boundry between two varying air masses. |
|
|
Term
|
Definition
| When the warm air mass dominate the colder one causing dry weather. |
|
|
Term
|
Definition
| When the cold air mass dominates the warm one causing clouds and storms. |
|
|
Term
|
Definition
| When there is an air mass with high pressure so the air moves away from the high pressured center to balance out and form equilibrium. |
|
|
Term
|
Definition
| When air flows into a low pressure area to form equilibrium. |
|
|
Term
|
Definition
| When hot air (pollution) gets trapped under cold air. |
|
|
Term
|
Definition
| The hot layer between the cold and hot zones during thermal inversion. |
|
|
Term
| Hadley, Ferel, Polar Cells |
|
Definition
Hadley- convective cells near the equator
Ferel- between the 0 degree and 30 degree line
Polar- between the 30 and 60 degree lines |
|
|
Term
|
Definition
| Due to the fact that the Earth is constantly spinning wind paterns get messed up and do not travel straight, but at curved angles. |
|
|
Term
| Problems with Dust Storms |
|
Definition
| Cause desertification and unsustainable farming. |
|
|
Term
|
Definition
| Release sulfur, when sulfur mixes with water and oxygen it produces aerosols which unnaturally cool the earth. |
|
|
Term
|
Definition
| Releases harmful soot and gases. Recently many are not even natural, but have been started by humans. |
|
|
Term
|
Definition
| Outdoor polution that can be pinned down to one point, factory. |
|
|
Term
|
Definition
| Outdoor pollution that cannont be pinned down to one place, but is a result of multiple things, cars. |
|
|
Term
| Air Pollution Control Act of 1955 |
|
Definition
| first air protection law to be passed |
|
|
Term
|
Definition
| Funded research into pollution control and encouraged emisiions standards for auto mobiles and point source polution |
|
|
Term
|
Definition
| Strict laws on air quality, formed limits for car emissions. Allowed people to be sued for damaging the air. First big law to come into play. |
|
|
Term
|
Definition
| Furthered the Act of 1970. Stricter regulation. |
|
|
Term
|
Definition
| Pollutants that harm human health. (CO, SO2, NO2, O3, Pb, Particulate Matter) |

|
Definition
| highly reactive and contributes to smog/acid precipitation. comes from motor vechicles. |
|
|
Term
|
Definition
| stratospheric ozone is good for humans but tropospheric is not, it is produced by smog and lies in the tropospheric zone. it is a secondary polutant because it is not dangerous until exposed to the suns rays. |
