Detailed explanation-1: -Ocean currents are great streams of water flowing both near the ocean’s surface and far below it. Prevailing winds (air currents) that blow over parts of the ocean push the water along, creating surface currents.

Detailed explanation-2: -A current is a large stream of water that flows through the ocean. Scientists put ocean currents in two categories: surface currents and deep currents. Surface currents move near the surface of the ocean. The figure below shows Earth’s major surface currents.

Detailed explanation-3: -Ocean currents are streamlike movements of water.

Detailed explanation-4: -River water does not flow in a straight line but must meander, fall, swirl, and collect according to its environment. We call these movements currents.
