In the open ocean,surface currents are most affected by
A)winds,the Coriolis force,the pressure-gradient force,and land boundary conditions.
B)frictional force (winds),the Coriolis force,and the pressure-gradient force.
C)winds and gyres.
D)both winds and the Coriolis force.

Question

Quizplus · Accepted Answer

Surface currents in the open ocean are primarily affected by three forces: frictional force, Coriolis force, and pressure-gradient force. So option B, which includes these three forces, is the best choice. Land boundary conditions can play a role in coastal currents, but not in open ocean currents. Gyres are a result of prevailing winds and Coriolis force, so option C is partially correct but not as accurate as option B. Option D is also partially correct, as winds do play a role, but the pressure-gradient force cannot be ignored.
