What is a water current?
Also, what is meant by water current?
Water currents can be found in streams, rivers and oceans throughout the world. Water current is the rate of movement in the water, and ways to describe water current include its speed and direction.
Also, how do water currents work? Near the shore, surface currents are driven by both the wind and tides, which draw water back and forth as the water level falls and rises. Meanwhile, in the open ocean, wind is the major force behind surface currents. As wind blows over the ocean, it drags the top layers of water along with it.
Beside above, what causes current in water?
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 storms. Currents are cohesive streams of seawater that circulate through the ocean.
What is air current and water current?
Prevailing winds (air currents) that blow over parts of the ocean push the water along, creating surface currents. Winds can also contribute to upwelling, or currents that move cold, nutrient-rich water from the bottom of the ocean to the surface.
