    What explains the Eastward flow of the equatorial counter-current?

    A)  The Earth's rotation on its axis

    B)  Convergence of the two equatorial currents

    C)  Difference in salinity of water'

    D)  Occurrence of the belt of calm near the equator

    Correct Answer: B

    Solution :

    Exp. [b] There are two equatorial current following from East to West direction around the Equator?North Equatorial and South Equatorial Current. A counter equatorial current flows in the opposite direction (i.e. from West to East). There is a high piling of waters taking place due to convergence of this to West moving currents near Eastern Brazil Coast. This leads to the rise the equatorial counter current in the direction of low level of water (i.e., in the Eastern part). Our Earth rotates from West to East hence, the piled up water comes down on its Eastern side and flows in Eastern direction.
