The surfaces on Earth heat up at different rates. If this is true, what would this cause?

• Cold mountains

• Wind

• Change in the gases of the atmosphere

High pressure areas always want to move toward a low pressure area, creating....

• heat

• cold

• wind

• air masses

This forms during the day when the land heats faster than the nearby ocean, causing wind to blow toward the land.

• sea breeze

• land breeze

This forms during the night when the land cools faster than nearby water, causing wind to blow toward the sea.

• Sea Breeze

• Land Breeze

This causes winds in the northern hemisphere to turn to the right. (due to the spinning of the Earth)

• Spin Effect

• Gravity Effect

• Coriolis Effect

• Wind Effect

How many different types of global wind are there?

• 3

• 6

• 4

steady winds that flow from east to west between 30°N and 30°S.

• Westerlies

• Easterlies

• Trade Winds

• Jet Streams

steady winds that flow from west to east between 30°N and 60°N, and 30°S and 60°S.
