WebForces between water molecules and friction between water layers cause deeper layers of water to move when surface water moves. Each successively deeper layer of water deflects further to the right of the wind in the Northern Hemisphere and to the left of the wind in the Southern Hemisphere. As depth increases the speed of each layer decreases. WebSep 27, 2024 · The currents descend back toward the ground at about 30° north latitude. As the current descends, it gradually moves from the northeast to the southwest, back toward the Equator. The consistently circulating patterns of these air masses are known as trade winds.

Ocean current Distribution, Causes, & Types Britannica
WebThe distribution of density is also used to estimate the deep currents. Direct observations of subsurface currents are made by deploying current meters from bottom-anchored moorings and by setting out neutral buoyant … WebThe density of water can also be affected by temperature. When the same amount of water is heated or cooled, its density changes. When the water is heated, it expands, increasing in volume. This is represented by the increase in the size of the box from Fig. 2.2 A to 2.2 C. cycloplegics and mydriatics
Ocean circulation - Understanding Global Change
WebThe ocean can be thought of as a collection of many currents moving in different directions and at different levels. Ocean circulation is the total movement of all ocean currents. … WebSep 12, 2024 · The heat source at the bottom of the pan heats the water, giving it more energy and causing the molecules to move faster. The temperature change also affects … WebMar 4, 2024 · Differences in water density affect vertical ocean currents (movement of surface ocean water to the bottom of the ocean and movement of deep ocean water to … cyclopithecus
