Front

Which of these best identifies a cold water current and explains its cause? North Equatorial Current, because it flows along the equator; Equatorial Counter Current because it flows west to east; East Australian Current, because it rotates in a counter-clockwise direction; Humboldt Current, because it moves water from south of the equator back toward the equator

Back

Humboldt Current, because it moves water from south of the equator back toward the equator
