U1-L2: Circulations in Earth's Oceans

What is an ocean current?

• A movement of ocean water that follows a regular pattern

• The curving of the path of a moving object due to Earth's rotation

• The movement of matter due to differences in density

• A sudden rise in sea level

What are the factors that affect surface currents?

• Continental deflections, global winds, and the Coriolis effect

• Only the Coriolis effect

• Only global winds

• Only continental deflections

What is the effect of the Coriolis effect on ocean currents?

• It causes currents to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere

• It causes currents to move in a straight line

• It has no effect on ocean currents

• It causes currents to stop moving
