The Coriolis effect causes ___________.

• global winds and surface currents to move in a curved path instead of a straight line

• continental deflection

• the Earth to rotate on its axis

• global winds and deep ocean currents to move in a curved path instead of a straight line.

What does the Coriolis effect have on surface currents in the northern and southern hemispheres?

• in general, there is no real effect

• in general, surface currents will flow counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.

• in general, surface currents will flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere.

• in general, they flow in the same direction

What happens when an ocean current meets a land mass?

• the water heats up

• the current is deflected

• a tidal bore forms

• an undertow recedes from the shoreline

If a cool surface current flows along a coastline, what effect might it have on the climate in that area?

• In general, it will bring warmer temperatures in the summer and milder temperatures in the winters

• In general, it will bring cooler temperatures in the summer and milder temperatures in the winters

• In general, it will have no long term effect on climate in that area.

• In general, it will bring cooler temperatures in the summer and colder temperatures in the winters

What is the initial source for global winds and convection in the atmosphere? 

• Unequal heating of the Earth by the sun.

• The rotation of the Earth

• Moon's gravity

• continental deflection

Describe convection.

• the transfer of heat energy across open space

• the transfer of heat energy by movement of water or air in a circular motion

• the transfer of heat energy by direct contact
