Wind Belts Lesson

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?

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.
