Answer in a paragraph:

What do you mean by ocean currents? Explain its types.

The movement of oceanic water on the surface and at the depths in a definite direction is called ocean current. The factors that generate ocean currents are:

• Earth’s rotation

• Prevailing winds and

• Differences in temperature and salinity of ocean water.

Ocean currents are classified into two types.

• Warm currents

• Cold currents

WARM CURRENTS: The movement of ocean currents from the low latitudes towards high latitudes is called warm current. E.g. Gulf Stream in Atlantic Ocean.

COLD CURRENTS: The movement of ocean currents from high latitudes to low latitudes is called cold currents. E.g. Labrador Current in Atlantic Ocean.
