Ocean Currents and Climate - University of Southern California

WebJul 30, 2024 · Warm water rises because it's less dense than cold water, so gravity has a part in the production of ocean currents. Cold water weighs more per unit volume than warm water, so gravity exerts a greater force … Deep below the surface, there are currents that are controlled by water density, which depends on the temperature and salinity of the water. Colder, saline water masses are more dense and sink; while warmer, fresher water masses … See more Density differences are the key to why ocean waters move. The oceans are mostly composed of less dense water near the surface over … See more Salt is really just a molecule in the ocean water, but collectively, that salinity plays an important role in the ocean circulation. The rule is simple - … See more Like the heated air in a hot-air balloon, heated water expands. Heat makes water lighter, so it rises. Solar heat absorbed at the equator causes water to expand. In this way, heated water raises the normal level of the sea … See more All this heating and cooling and melting and thawing creates a layered ocean: warmer fresher water on top, cold salty water at the bottom. Organisms move from one layer to another, and plant and animal remains … See more midform infinity teva

What is a surface ocean current? [Ultimate Guide!]

WebThe ocean currents, the movement of the ocean in the surface layer, are driven mostly by the wind. In certain areas near the polar oceans, the colder surface water also gets saltier due … WebSurface currents are controlled by three factors: global winds, the Coriolis effect, and continental deflections. These three factors keep surface currents flowing in distinct … WebSurface currents control the water’s salinity. ... The Atlantic features a circulation pattern of warm surface currents, including the Gulf Stream, that brings warm surface waters from the tropics northward into the North Atlantic. There, in the seas surrounding Greenland, the water cools; sea ice forms removing freshwater from the water ... newsrecord obits gillette wy
