Atmosphere~BW

3. the concentration of ozone in the stratosphere
5. 12 to 50 km, Ozone held here, absorbs UV radiation
10. a warming of Earth's surface and the air above it; caused by gases (water vapor, carbon dioxide, and methane) in the air that trap energy from the sun
16. a powerful funnel-shaped column of spiraling air that touches the ground
17. air passing over warm surfaces gains buoyancy
20. a body of air with horizontally uniform temperature, humidity, and pressure.
21. the uppermost layer of the atmosphere
22. an usually brief, heavy storm that consists of rain, strong winds, lightning, and thunder
23. weather phenomenon caused when warm water from the western Pacific Ocean flows eastward; milder winter temperatures and less snow than usual

1. the temperature at which the water vapor in the air becomes saturated and condensation begins
2. a hurricane intensity scale that relates hurricane damage to wind speeds and central air pressures.
4. cloud formation that occurs when warm moist air is forced to rise up the side of a mountain
6. the largest source of human caused pollution in the United States
7. if warm and cool air collide, the warm air will be forced up
8. a percentage of the maximum amount of water vapor the air can hold at its current temperature
9. a large, powerful windstorm that forms over warm ocean waters
11. a boundary between air masses that don't move possibly causing rain for several days
12. used to classify a tornado based on wind speed and damage
13. the abnormal rise of the sea along a shore as a result of strong winds
14. the layer closest to Earth, where almost all weather occurs; the thinnest layer
15. an irregularly recurring upwelling of unusually cold water to the ocean surface along the western coast of South America that often occurs following an El Niño
18. 50 to 80 km, most meteorites burn up here
19. the mass of air surrounding the Earth
