Layers Of The Atmosphere Quiz 2 Flashcards
What air pressure is closer to earth?
More air pressure is closer to earth also more density.
Is the atmosphere heavy or light?
Heavy
What air pressure is farther away from earth?
Less air pressure and less density
Blank1 is a major factor in our blank2
Blank1=heat
Blank2= weather
The blank comes from the sun
Heat
Blank1 is usually blank2 using a blank3
Blank1= air temperature Blank2= measured Blank3= thermometer
Why do thermometers work?
Thermometers work because liquids expand when they are heated and contract when they are cooled.

The Suns Rays.
What is the air above the earth warned by?
The earths surface
Warm air does what?
Cooler air does what?
Warm air rises
Cool air sinks.
T or F
Warmer air = low pressure.
Cooler air= high pressure
T
T or F
A wind is a horizontal movement of air from an area of high pressure to an area of low pressure.
T
Are winds caused by differences in air pressure?
Yes
What are global winds?
Wind that blow over long distances
What are Local winds?
Winds that blow over short distances
Does air rise at the equator?
Yes
Does air sink at the poles?
Yes
What is a convection current?
Air blows from the equator to the poles and from the poles to the equator
What is the Coriolis Effect?
Because of earths rotation, global winds do not blow straight up and down from the equator to the poles and back.
Are winds curved or straight?
Curved.
What way do northern hemisphere winds turn?
To the right.
What way do the winds turn in the Southern Hemisphere?
To the left
