Ocean Currents

Front

What can cause an increase in density that results in a deep ocean current?

Back

Warm water loses energy to its surroundings and cools.

Front

Which movement of ocean water has the greatest direct effect on the growth of producers? Options: upwelling, deep current, surface current, convection current

Back

upwelling

Front

Which three factors most directly affect surface currents in the oceans?

Back

surface winds, the Coriolis Effect, and continental deflection

Front

How does convection cause ocean currents?

Back

During the process of convection, energy in warm water is lost to its surroundings. The water cools, becomes denser, and sinks.

Front

Stream like movements of water

Back

Ocean Currents

Front

Currents change direction by hitting the continents or other large landmass.

Back

Continental Deflections

Front

Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere.

Back

Coriolis Effect

Front

Which of the gases listed in Dom’s table is less common in ocean water than it is in the atmosphere? Options: argon, oxygen, nitrogen, carbon dioxide

Back

nitrogen

Front

Movements of ocean water located far below the surface.

Back

Deep Currents

Front

Currents are on the surface or less than a 100 meters deep (330 feet). Options: Ocean Currents, Convection Currents, Deep Currents, Surface Currents

Back

Surface Currents
