Detailed explanation-1: -These currents are called gyres. An ocean gyre is a large system of circular ocean currents formed by global wind patterns and forces created by Earth’s rotation. The movement of the world’s major ocean gyres helps drive the “ocean conveyor belt.” The ocean conveyor belt circulates ocean water around the entire planet.

Detailed explanation-2: -Convection is the circular motion that happens when warmer air or liquid-which has faster moving molecules, making it less dense-rises, while the cooler air or liquid drops down.

Detailed explanation-3: -Convection currents are movements of fluid caused by a temperature or density difference within a material. Convection currents are only seen in gases and liquids because particles within a solid are fixed in place. Warm air rising toward a house’s ceiling or attic is a simple example of convection currents.

Detailed explanation-4: -Natural convection is a mechanism of heat transportation in which the fluid motion is not generated by an external source. Instead the fluid motion is caused by buoyancy, the difference in fluid density occurring due to temperature gradients.
