Detailed explanation-1: -The streams of water that flow constantly on the ocean surface in definite directions are called ocean currents.

Detailed explanation-2: -Ocean currents are the continuous, predictable, directional movement of seawater driven by gravity, wind (Coriolis Effect), and water density. Ocean water moves in two directions: horizontally and vertically. Horizontal movements are referred to as currents, while vertical changes are called upwellings or downwellings.

Detailed explanation-3: -Ocean currents are the continuous, predictable, directional movement of seawater. It is a massive movement of ocean water that is caused and influenced by various forces. They are like river flows in oceans.

Detailed explanation-4: -Gyres. Ocean surface currents tend to form ring-like circulation systems called gyres. A gyre is a circular ocean current formed by a combination of the prevailing winds, the rotation of the Earth, and landmasses. Continents interfere with the movement of both surface winds and currents.

Detailed explanation-5: -The forward movement of surface water of the oceans under the influence of prevailing winds is called drift whereas the ocean current involves the movement of Oceanic water in a definite direction with greater velocity.
