Quizplus · Accepted Answer

Deep ocean currents are mainly driven by differences in water density, which is influenced by variations in temperature and salinity. However, these currents are also modified by other factors, including the Coriolis effect and differences in pressure gradients caused by variations in gravity. Land masses can also play a role by blocking or diverting ocean currents. Wind, on the other hand, primarily affects surface ocean currents rather than the deeper currents. Therefore, option B is the best choice as it correctly identifies density differences as the primary driver of deep ocean currents and mentions differences in temperature and salinity as modifiying factors.
