Atmospheric Processes

Warm air...

• sinks

• rises

Cold air ...

• sinks

• rises

Currents of circulating air or other fluid caused by differences in temperature

• Jet streams

• Trade winds

• Coriolis

• Convection

If the Earth did not rotate, air at the Equator would simply

• Sink and move toward the poles.
• Rise and move toward the poles.
• Stay stationary.
• None of the above.

The Coriolis Effect is caused by

• Earth rotating around the sun
• Earth rotating on its axis
• The tides
• Gravity

Hadley, Ferrel, and polar are the names of

• bears

• feuding Kentucky families

• atmospheric circulation cells

• cloud types

The Hadley Cell begins at....

• The Equator

• 20 degrees N&S

• The North Pole

• 40 degrees N&S

What are trade winds?

• Surface winds blowing towards the equator

• Atmospheric winds

• Winds blowing away from the equator

• Low pressure winds

Fast-flowing currents of air high in the troposphere are

• Hadley cells

• Jet streams or "atmospheric jets"

• Trade winds

• Altostratus

What is the effect of global circulation on temperatures around the Earth?

• global atmospheric circulation does not affect temperature

• global atmospheric circulation makes hot places hotter and cold places colder

• global circulation moderates temperatures, warming the poles and cooling the equator

• temperatures change in a random fashion
