GEOLOGY

Detailed explanation-1: -These currents move water masses through the deep ocean, taking nutrients, oxygen, and heat with them.

Detailed explanation-2: -Alternate rise and fall of water on the ocean surface is called an ocean current.

Detailed explanation-3: -Ocean currents are streams of water flowing constantly on the ocean surface in definite directions. Ocean currents may be warm or cold. The Labrador Ocean current is cold current while the Gulf Stream is a warm current. The areas where the warm and cold currents meet provide the best fishing grounds of the world.

Detailed explanation-4: -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.
