Even fish and mammals living in the ocean may have their destinations and food supply affected by currents. Winds Produce Currents. If winds blow constantly from the same direction on the oceans surface for long durations, ocean surface currents can be produced. Currents are similar to rivers of water moving in the ocean. Currents range in size from relatively small longshore currents near a beach, to currents that span ocean basins. it happens throughout the ocean. m/s, determine the power supplied to the engine when t = 5 s.

Surface currents are created by three things: global wind patterns, the rotation of the Earth, and the shape of the ocean basins. Deep currents are driven by temperature and water density/salinity. Deep ocean currents move cold water toward the equator. causes currents in open water to move in a curved path rather than a straight path. It shares minerals & pollution attached to it becomes profoundly adulterated & later negligible. when surface currents meet continents, the currents are deflected and change direction. the horizontal movement of water due to surface winds can bring about vertical movements of water. Here are 4 ways we use it. Since the Gulf Stream also extends toward Europe, it warms western European countries as well. The Gulf Stream is a strong ocean current that brings warm water from the Gulf of Mexico into the Atlantic Ocean. surface create surface currents in the ocean.
