Which event typically causes upwelling?

Answer

A

Wind blows warm water away from the shore.

B

Warm water rises to the surface of the ocean.

C

Neap tides move cold water away from the shore.

D

Cold water falls to the bottom of the ocean and pushes warm water up.

Upwelling occurs when wind pushes surface water away from a coastline. Cold, nutrient-rich water from deeper in the ocean then rises to replace it. So the correct choice is “Wind blows warm water away from the shore.”
