Question

Which amongst the following is NOT one of the causes of Ocean Currents?

Options

• Level of Salinity

• Temperature

• The Earth's Revolution

• Planetary Winds

Answer 1

The Earth's Revolution

Explanation:

Ocean currents are mainly caused by factors like temperature differences, salinity levels, and planetary winds. Warm water tends to move toward cooler areas, and differences in salinity affect the water’s density, both of which drive movement. Planetary winds, like trade winds and westerlies, push surface water in specific directions, forming surface currents. While the Earth’s rotation (causing the Coriolis effect) influences the direction of currents, the Earth’s revolution around the Sun does not directly affect ocean currents.
