Question | Answer |
---|---|
What instrument measures air pressure? | Barometer |
How is Earth's atmosphere warmed? | Greenhouse gases that absorb infrared radiation |
How does water vapor enter the atmosphere? | Evaporation and Transpiration |
What atmospheric condition will increase the rate of evaporation? | A hot, dry and windy day |
When air temperature decreases will the temperature become closer or further from dew point? | Closer to dew point |
As air moves up in the troposphere, what happens to the temperature? | Temperature decreases |
What causes surface ocean currents? | Atmospheric wind |
What ocean current brings warm water to higher latitudes? | Gulf Stream |
What ocean current brings cold water to lower latitudes? | Peru Current |
What causes ocean currents and surface winds to deflect to the right in the Northern Hemisphere? | Earth's rotation (coriolis Effect) |
What causes different pressure systems to form? | Uneven heating of Earth's atmosphere |
What kind of relationship do air temperature and density have? | Indirect |
What kind of weather would cause a high reading on a barometer? | Cold, dry with clear skies |
What does a Sling Psychrometer measure? | Relative humidity |
How does air in a low pressure system flow? | rises and moves counterclockwise and inward |
What is the air doing over the South Pole? | Sinking and diverging |
How do clouds form? | Air rises, expands and cools |
What is the air doing at the Equator? | Rising and converging |
What happens to the wind velocity when the isobars are closer together? | Wind velocity increase |

What type of heat transfer is due to difference in density? | Convection |
What type of heat transfer requires contact? | Conduction |
Why does the air cool while going up the windward side of a mountain? | The air cools due to expansion |
What kind of process is evaporation? | A cooling process |
What type of wind moves pressure systems? | Planetary Winds |
