Question

because of the coriolis effect, gyres in the northern hemisphere circulate in which direction?

ο south

o counterclockwise

o north

o clockwise

Explanation:

The Coriolis effect causes large - scale oceanic gyres (circular ocean current systems) in the northern hemisphere to circulate in a clockwise direction. In the southern hemisphere, gyres circulate counter - clockwise. The options "south" and "north" are directions of movement along the north - south axis, not the rotational direction of gyres. And "counterclockwise" is the direction of gyres in the southern hemisphere. So the correct option is the one related to the clockwise rotation of northern hemisphere gyres due to the Coriolis effect.

Answer:

D. clockwise
