What is wind defined as?

• Horizontal movement of air.

• Random movement of air.

• Circular movement of air.

• Vertical movement of air.

Warmer air is ​ (a)   dense, and tends to ​ (b)   . Cold air is ​ (c)   dense, and tends to ​ (d)  

• less
• rise
• more

• equally 

Describe in your own words- what is air pressure?

True or False: A "Low" is a low pressure area that is defined as an area that has air pressure that is lower than the surrounding areas. Sometimes this is also defined as a place that has lower than "standard" air pressure (which is sort of like the average, or expected air pressure)

• True

• False

The weather at a low pressure system, or a Low, is often:

• Sunny with no wind

• Cloudy and Rainy

Why does the wind "spiral" around a center of high and low air pressure?

• Because cold air sinks

• Because the Earth is spinning (this is called the coriolis effect)

• Because gravity pushes it to the side

• Because the buildings block the air as it blows across the surface

Why is the air rising at the Equator?

This video just talked about a LOT of information about the wind belts, very fast! It's okay if you didn't pick up a lot of that. Write anything you learned here:
