Currents/Wind

What causes wind?

• differences in air pressure

• differences in gravity

• differences in oxygen

• Coriolis Effect

Which statement correctly defines wind?

• movement from areas of low to high pressure

• movement from N to S

• movement from areas of high to low pressure

• movement from S to N

In the Northern Hemisphere, winds traveling north appear to curve east because of the:

• trade winds

• convection currents

• Coriolis Effect

• pressure

The Coriolis effect is the curving of wind across Earth. What causes winds to curve?

• Earth's revolution around the sun

• Earth's magnetic field

• Earth's rotation

• Gravity

The __________ is a surface current that flows along the eastern US and brings warm water to Europe.

• California

• Gulf Stream

• North American Gyre

• West Wind Drift

Gyres in the southern hemisphere are surface currents that turn _________ due to the Coriolis Effect.

• clockwise

• counter clockwise

• toward the right

• their assignments in on time

The five large circular ocean currents are called...

• whirlpools

• gyres

• currents

• belts

How does the West Wind Drift (Antarctic Circumpolar Current) wrap all around the Earth?

• It is deflected by the continents

• There is no Coriolis Effect at the S Pole

• It flows between the continents

• There is no wind

This image explains that...

• The poles receive more concentrated solar energy.

• Warmer temperatures are found near the poles

• The equater receives solar energy spread over a large area

• The equator received more concentrated solar energy
