Global Winds and Ocean Currents

Global Winds and Ocean Currents

By Kristen Yarka

Wind is created by unequal heating and cooling.

Land heats up faster and cools down faster than water.

Multiple Choice

Air moves from _______ pressure to ________ pressure.

• high to low

• low to high

Multiple Choice

The arrow above the water is coming down and is blue because

• the water is warm so it warms the air and warm air sinks.

• the water is cold so it warms the air and cool air sinks.

• the water is cold so it cools the air and cool air sinks.

• the water is warm so it warms the air and cool air sinks.

Multiple Choice

Convection currents form when

• there are no temperature differences.

• there are temperature differences.

• each surface is exactly the same temperature.

• candy is given out for Halloween.

Multiple Choice

The arrow above the land is coming down and is blue because

• the land is warm so it warms the air and warm air sinks.

• the land is cool so it cools the air and cool air sinks.

• the water is warm so it cools the air and warm air sinks.

• the land is warm so it warms the air and cool air sinks.

Multiple Choice

The arrow above the water is going up and is red because

• the water is warm so it warms the air and warm air sinks.

• the water is warm so it cools the air and cool air sinks.

• the water is warm so it warms the air and warm air rises.

• the land is warm so it warms the air and cool air sinks.
