Ocean Currents

We know that ocean water moves continuously.

But this ocean water does not move randomly. It moves in specific directions.

The movement of ocean water in a particular direction to large areas is called the ocean currents.

Ocean currents are of two types: warm ocean currents and cold ocean currents.

Generally, warm currents originate near the equator and move the water towards the pole.

For example, the Gulf stream is a warm current.

Cold currents carry the cold water from polar or higher latitudes to lower latitudes.

For example, the labrador ocean current is a cold current.

While warm currents bring warm water over the land surface, cold currents bring cold water to the land surface.

So ocean currents influence the temperatures over land area.

The areas where warm and cold currents meet provide the best fishing grounds as many fishes live in those areas.

Such meeting currents are present in seas around Japan and the eastern coast of North America.

Due to the mix of hot and cold currents, these areas will experience fog, making it difficult for the ships to move.
