Q. 1 C
Choose the correc A. due to rotation of earth
B. due to variation in temperature
C. due to earth’s movement
D. all the above
OPTION D is correct because all the given factors play a role in producing ocean currents.
Due to variation in temperature, there is warm and cold ocean currents.
Due to earth’s movement around the sun and moon’s movement around the earth, there is tidal forces acting on water bodies.
Due to earth’s rotation, there is the Coriolis force that push the ocean currents to rotate in opposite directions in each hemisphere.
Hence, all of the above factors influence the creation and the movement of the ocean currents.
