Question
Mainly Ocean currents are_____________.
- Caused by an abnormal shape of the continents
- Caused by variation in temperature
- Caused by variation in density
- Caused by wind moving over the sea surface
Hint:
Winds
The correct answer is: Caused by wind moving over the sea surface
- Mainly ocean currents are caused due to wind moving over the sea surface.
- So, the correct option is d.
- Ocean currents can be caused by-
- Wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storm.

________is a warm ocean current.
- The surface waters of the Kuroshio Current are warm and salty.
- This is because the Kuroshio starts in the tropics where the westward flowing North Equatorial Current reaches the western boundary of the North Pacific.
