What is the primary driving force for surface ocean currents?
A
density layering
B
global winds
C
water temperature differences
D
salt concentration
Explanation: 

Detailed explanation-1: -Surface currents are powered by the sun and driven by the wind. The sun drives the global wind systems on Earth. When this wind blows over the surface of the ocean, it causes waves to form and the water at the surface to move. The force of the wind pushing on the water results in what are known as surface currents.

Detailed explanation-2: -Surface currents in the ocean are driven by global wind systems that are fueled by energy from the Sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth’s rotation, and the position of landforms that interact with the currents.

Detailed explanation-3: -Unequal Heating: Effect of the Sun on Global Winds. The two main factors affecting wind patterns are 1) the heat distribution between the earth’s equator and poles, and 2) the constant rotation of the planet. The sun is Earth’s primary energy source.

Detailed explanation-4: -The winds pull surface water with them, creating currents. As these currents flow westward, the Coriolis effect-a force that results from the rotation of the Earth-deflects them. The currents then bend to the right, heading north.
