A. OCEAN CURRENTS act like large rivers in the Earth's oceans and help spread Earth's heat and shape climates.

These ocean currents move across distance. The move warm water from the tropics towards the poles. They also move cool water from the poles towards the tropics. The water temperature affects the air temperature near it. Warm water from the tropics warms the air and cool water from the poles chills the air.

The answer is c) organisms that are sensitive to changes in temperature would die.
