Question

Which factors influence ocean currents?

• A. Earth's rotation
• B. Winds across ocean
• C. Density of water
• D. All of the above

Answer 1

The correct option is D All of the above

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.
