What causes air pressure |
Air pressure is the force of air molecules pushing on an area |
|
|
Where would air pressure be the Highest? |
At the bottom at Death Valley |
|
|
Air at de level is denser that air at High Altitudes |
Since its greater at sea level,the air molecules are pushed closer together. |
|
|
What causes wind to blow? |
Earths surface causes such pressure,which sets air in motion |
|
|
How does the coriolis effect influence how global winds blow? |
Global winds curve,because they cannot flow directly from the poles to equator |
|
|
Compare and contrast doldrums and horse latitudes |
Compare:Both have calm regions. Contrast: horse latitudes are low pressure and Doldrums are high pressure |
|
|
Name three global winds |
Westerlies,easterlies,and trade winds |
|
|
What causes the trade winds to blow? |
They blow from the horse latitudes to the equator |
|
|
What causes the westerlies to blow? |
They blow from horse latitudes to the poles |
|
|
What causes local wind patterns? |
By the air over the land rises and expands |
|
|
What is evaporation? |
Process by which a liquid changes to a gas |
|
|
What is condensation? |
A gas,such as water vapor,which changes into a liquid |
|
|
What process loses energy? |
Condensation |
|
|
What process gains energy? |
Evaporation |
|
|
What is saturation |
It's how evaporation and conduncation are equal |
|
|
What is dew point? |
Temperature at which air is given amount of water vapor will reach saturation |
|
|
How do clouds form? |
When air rises it cools,it goes to its dew point |
|
|
Three types of clouds? |
Cumulus,stratus,and cumulonimbus |
|
|
What is precipitation? |
Any type of liquid that falls to earths surface |
|
|
Three types of precipitation |
Hail,snow,rain |
|
|
How does water vapor enter the air? |
Evaporation from bodies of water |
|
|
Why does more precipitation fall over the ocean than land |
Water from bodies of water evaporates more often into the air above it |
