Inter-tropical Convergence Zone

area where warm, moist air rises close to the equator

Winds blowing out of the north toward the south in the southern hemisphere will appear to

be deflected toward the east.

A zone of high atmospheric pressure results when there is relatively __________ air aloft.

cool, dry

counterclockwise.

Tropic of Cancer

located at 23.5° N latitude

Earth's polar regions (above 60° latitude) are classified as deserts because

summer solstice

The two factors that are most important in determining the density of air are

temperature and water vapor content
