    Question

    The global pattern of prevailing winds drives the cell - like circulation pattern of ocean currents called

    A.

    Trade winds

    B.

    Gyres

    C.

    Jet Streams

    D.

    Shallow drifts

    Correct option is B

    Introduction
    · Ocean circulation is a large-scale movement of waters in the ocean basins, driven by primary forces like solar heating, wind patterns, and the Coriolis effect.
    · Surface currents are primarily governed by the frictional drag of prevailing winds, which transfer energy from the atmosphere to the hydrosphere.
    · These circulation patterns play a vital role in global heat redistribution, influencing regional climates and marine biological productivity.
    Information Booster
    · Gyres is the correct answer, referring to the large systems of rotating ocean currents that form circular or "cell-like" patterns across major ocean basins.
    · These are formed by the interaction of the global wind belts (like the Trades and Westerlies) with the Coriolis force and the boundaries of the continents.
    · There are five major subtropical gyres: the North and South Pacific, the North and South Atlantic, and the Indian Ocean Gyre.
    · The center of these gyres is typically a region of relatively calm water and high salinity, often characterized by the accumulation of floating debris, such as the Great Pacific Garbage Patch.
    · In the Northern Hemisphere, these circular currents rotate in a clockwise direction, while in the Southern Hemisphere, they rotate counter-clockwise due to the Coriolis effect.
    Additional Knowledge
    · Trade winds are the permanent East-to-West prevailing winds that flow in the Earth's equatorial region; while they act as a "driver" for the ocean currents, they are an atmospheric phenomenon rather than the resulting oceanic circulation cells.
    · Jet Streams are fast-flowing, narrow, meandering air currents located in the upper atmosphere (near the tropopause) that influence weather systems but do not describe the circular rotation of the oceans.
    · Shallow drifts (or surface drifts) refers to the movement of surface water in response to local winds, but this term lacks the specific definition of a closed-loop, basin-wide circulation cell that characterizes a gyre.
    · Boundary currents, such as the Gulf Stream, are specific components of these gyres that transport warm water from the equator toward the poles, illustrating the heat-transfer function of these oceanic cells.
