Ocean currents are the regular movements of water in the oceans. They move in a circular pattern around the oceans. There are different types of ocean currents.
Types of Ocean Currents Based on temperature
Warm currents: These currents flow from low latitudes in the tropical zone towards the high latitudes in the temperate and sub-polar regions. These currents bring warm water to cold regions.
Cold currents:Â These currents flow from the polar regions to the equatorial regions. These currents bring cold water to warm regions.
Types of Ocean Currents Based on Depth
Surface currents:Â These currents make about 10% of all water in the ocean.
Deep water currents:Â These currents make about 90% of all water in the ocean.
