Detailed explanation-1: -Gyres Surface water circulates in oceans in massive circular patterns called gyres. The major surface currents (eastern boundary, western boundary, and equatorial current) in each ocean link to form a circle.
Detailed explanation-2: -These deep-ocean currents are driven by differences in the water’s density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation.
Detailed explanation-3: -1) When warm ocean waters move towards cooler regions it is called a ‘warm ocean current’. 2) When cold ocean waters move towards hotter regions, it is called a ‘cold ocean current’.
Detailed explanation-4: -Circulating wind and ocean currents distribute energy and matter all around the globe. Surface currents are primarily driven by wind and Earth’s rotation. Earth’s rotation causes the pathway of both air and water to appear to curve rather than travel in a straight line. This is known as the Coriolis effect.
