2. Rain with a slightly lower pH than regular rain water. It is caused from sulfur oxides from burning coal mixing into rainwater.
3. A front where cold air moves in under a warm air mass.
4. A line on a weather map that joins places that have the same air pressure
9. A boundary between air masses that don't move possibly causing rain for several days
10. winds that blow steadily from specific directions over long distances
11. the lower part of the thermosphere, where electrically charged particles called ions are found
14. dark, low-level clouds accompanied by light to moderately falling precipitation.
15. The movement of air caused by differences in air pressure

1. the front of an advancing mass of warmer air
2. concentration trace substances, such as carbon monoxide, sulfur dioxide, nitrogen oxides, hydrocarbons, and solid particulates, at a greater level than occurs in average air
5. Also known as London-type smog; created by burning coal.
6. The outer layer of the thermosphere, extending outward into space.
7. Winds that mostly affect the weather in the US and are located between 30 and 60 degrees latitude. Move West to East.
8. Winds that blow over short distances. Example: Sea Breeze and Land Breeze
12. When warm and cold fronts collide/combine
13. A brownish haze that is a mixture of ozone and other chemicals, formed when pollutants react with each other in the presence of sunlight.
