GEOLOGY

Detailed explanation-1: -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-2: -The correct answer is Ocean current. Ocean currents are such streams of ocean water that move in a certain direction throughout the year on the surface of the ocean.

Detailed explanation-3: -Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. Currents are cohesive streams of seawater that circulate through the ocean.

Detailed explanation-4: -Wind blowing over water will move the ocean water underneath it in an average direction perpendicular to the direction the wind is traveling. As wind blows over the surface layer of water, friction between the two pulls the water forward.

Detailed explanation-5: -Waves, tides and currents are the major movements of the ocean.
