Cold currents are currents that carry cold water from the polar regions towards the equator. They are typically found on the western sides of ocean basins. Some examples of cold currents include the Humboldt Current, the Canary Current, and the Benguela Current.
Warm currents are currents that carry warm water from the equatorial regions towards the poles. They are typically found on the eastern sides of ocean basins. Some examples of warm currents include the Gulf Stream, the Kuroshio Current, and the Brazil Current.
Cold and warm currents play an important role in the global climate. They help to distribute heat around the world, and they can influence weather patterns. For example, the Gulf Stream helps to keep Europe warm by transporting warm water from the Caribbean Sea to the North Atlantic Ocean.
The movement of ocean currents is driven by a number of factors, including the Earth's rotation, the wind, and the density of the water. Cold currents are typically denser than warm currents, so they tend to sink below them. This can create a layering effect in the ocean, with cold water near the bottom and warm water near the surface.
