• sink to the bottom

• are destroyed by sunlight

• become coral reefs

What is one reason that ocean currents can't go directly from the equator to the poles?

• salinity

• temperature

• Coriolis effect

• too far

• clockwise and counter clockwise

• left and right

• North and South

Ocean currents transfer heat to the atmosphere when:

• the air has a temperature greater than the temperature of the ocean surface.

• the ocean surface temperature is the same as the temperature of the air.

• the ocean surface temperature is greater than the temperature of the air.

• the Giants make a miraculous comeback and with this years Superbowl!

What factor causes surface currents north and south of the equator to move in different directions?

• the sun's energy

• the Coriolis Effect

• the density of water

• continental deflection

What action can cause an increase in density that would have an effect on deep ocean currents?

• evaporation causing an increase in salinity

• warmer ocean currents causing a decrease in density

• warmer ocean currents causing an increase in density

• a river adding freshwater to the nearby ocean water

The huge circular surface currents that occur in each of the world's oceans.

• Coriolis effect

• deep ocean currents

• gyres

• density
