Weather

8. rainfall made acidic by atmospheric pollution; main cause is the industrial burning of coal and other fossil fuels, which releases sulfur and nitrogen oxides, which then combines with atmospheric water to form acids
9. The forward edge of an advancing mass of cold air that pushes under a mass of warm air. Cold fronts often cause heavy precipitation and/or thunderstorms.
10. fog or haze combined with smoke and other atmospheric pollutants
11. the warming of the Earth's surface and the air above it caused by gases in the air that trap energy from the sun; the heat-trapping gases are called greenhouse gases and the most common are water vapor, carbon dioxide, and methane
12. a radar tracking system using the Doppler effect to determine the location and velocity of a storm, clouds, precipitation
14. the lowest layer of the atmosphere and cloud formation and weather occurs here.
15. an instrument measuring atmospheric pressure

1. is a shell of electrons and electrically charged atoms and molecules, Aurora Borealis occurs here that is in the lower end of the Thermosphere
2. Cloud type that appears feathery or wispy, “curl of hair”, form in very high altitudes and made of ice crystals
3. the movement caused within a fluid (like air) by warmer, less dense material to rise, and colder, denser material to sink, resulting in heat transfer
4. A form of oxygen; O3
5. to of the atmosphere, satellites orbit here, the upper end of the Thermosphere, blends into space
6. a narrow, variable band of very strong, predominantly westerly air currents encircling the globe several miles above the earth.
7. a violent, tropical, cyclonic storm of the western North Atlantic, having wind speeds of or in excess of 72 miles per hour
13. invisible rays that come from the sun and it can cause skin cancer
