Atmospheric Circulation 2

What is wind?

• Large scale movement of air caused by differences in air pressure

• Large scale movement of CO2 caused by differences in air pressure

• Large scale movement of air caused by differences in composition

• Large scale movement of temperature caused by differences in air pressure

True or false - warm air rises, cools and condenses and forms clouds, this is called low pressure

• True

• False

Why are there global winds?

• because the cold air sinkes from the poles to the equator
• because the earth is rotating from east to west
• because the sun heats the air at the equator more than anywhere else on earth

How does the Coriolis Effect influence hurricanes and cyclones

• determines how powerful they will be

• determines where they will gain strength

• determines where they form

• determines the direction of the wind rotation

Objects in the NORTHERN Hemisphere deflect to which direction due to the Coriolis Effect?

• Left

• Up

• Down

• Right

The Coriolis Effect is caused by

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