How can the movement of the Gulf Stream affect the areas around it and how can it be described? they move warm water towards the poles. The warm ocean currents originate near the equator and move towards the poles. The rising of cold water from deeper layers to replace warmer surface water. Ocean water is on the move, affecting your climate, your local ecosystem, and the seafood that you eat. A nucleus has a radius of $4.5 \times 10^{-15} \mathrm{~m}$. They are caused by temperature differences in the water, and the earth's rotation. Do all geological displacements cause tsunami? it happens throughout the ocean. Deep ocean currents move cold water toward the equator. Changes in this temperature can influence the behavior of fish, cause the bleaching of corals, and affect weather along the coast. it causes water to expand. the westward currents are deeper and faster this effect is known as westward intensification its caused by the Coriolis effect the terrain is steeper on the western edge causing currents to move faster. The wind blows the water at the surface in a certain direction and forms the surface 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. Wind is the single biggest factor in the creation of surface currents. cin >> temperature; It increases the density of the ocean water.
