deep ocean currents form by the differences in the density of ocean water
Warm ocean currents cool as they flow along a coastline away from the equator because sand and minerals are transported by ocean currents away from the equator.
Ocean floor.
Along cold water currents from the poles to the equator.
Along warm water currents from the equator to the poles.
deep currents streamlike movement of water that flow very slowly along the ocean floor. surface current can influence the climate of land are they flow past.
Cold ocean currents sink under warm ocean currents to form deep ocean currents.
As water is on top of the ocean, wind pushes it along, creating a current. As it warms, it interacts with lower colder waters, pulling them along with it. As water cools, it rises and this interaction creates ocean currents.
The shape of a continent can influence ocean currents by directing their flow. For example, a narrow passage between two landmasses can funnel and accelerate ocean currents, while a broad continental shelf can slow down and disperse currents. Additionally, the presence of peninsulas, bays, and capes can create eddies and turbulence in ocean currents.
Where a river which transmits a great deal of material arrives at the sea and there is little tidal range a delta will form. Example the Nile into the Mediterranean or the Mississippi into the Gulf of Mexico. The Amazon & the Congo, which flow into an Ocean, the Atlantic in these examples, do not form deltas because the ocean currents distribute the outflow of material into & along the ocean currents.
Ocean currents is what forms surface currents. This starts deep in the ocean.
