Correct ANSWER – Option C
EXPLANATION
Factors
Influencing Nature and Movement of Ocean Currents:
1.
Factors related to the earth’s rotation: Gravitational force and
force of deflection.
2.
Factors originating within the sea: Atmospheric
pressure, winds, precipitation, evaporation and insolation.
3.
Factors originating within the sea: Pressure gradient, temperature
difference, salinity, density and melting of ice.
4.
Factors modifying the ocean currents: Direction and shape of the
coast, seasonal variations and bottom topography.
