WIND BELTS

Wind belts are predictable wind

patterns caused by the:

 

1. Earth’s rotation *Coriolis Effect

   

2. Unequal heating of the sun.

 

*Due to differences in temperature, wind travels from areas of high density(COLD) to areas of low density (WARM).

  **Remember convection currents?

Fill in the Blanks

Would the winds in this image be easterlies or westerlies, if you are facing North? Explain your answer.

Multiple Choice

During the land breeze, what starts moving the cooler air out and warmer air in?

• conduction

• convection

• radiation

Multiple Choice

Air in the atmosphere is heated unevenly by the sun, causing

• wind patterns.

• cloud formation.

• volcanic activity.

• water condensation.

Multiple Choice

Is this a land or a sea breeze?

• land breeze

• sea breeze

Multiple Choice

Air at the poles is colder and denser so it_______________.

• rises

• circulates

• stagnates

• sinks

Multiple Choice

Air is warmer and less dense at the equator because the equator receives more____________________.

• wind

• solar radiation

• air pressure

• condensation

Multiple Choice

In the Northern Hemisphere, winds traveling north appear to curve east because of the:

• trade winds

• convection currents

• Coriolis effect

• polar easterlies

Multiple Choice

Which is NOT a characteristic of global winds?

• They occur as global wind belts.
• They occur within small areas.
• They occur over large areas.
• They blow steadily over long distances.

Multiple Choice

The Coriolis effect is the curving of wind across Earth. What causes winds to curve?

• Earth's revolution
• Earth's magnetic field
• Earth's rotation
• Earth's gravitational pull

Multiple Choice

Use the diagram to determine which statement is correct.

• The air at location 3 is more dense than the air at location 6.
• The air at location 2 is rushing in to take the place of the colder air at location 3.
• Location 1 heats up and cools down slower than location 7.
• High pressure air at location 2 is taking the place of the low pressure air at location 3.
