WebOcean currents are produced by friction created by wind blowing over the water surface. However, the direction and speed of water currents do not match those of the wind currents above them. A 20 km/h eastward wind does not produce a 20 km/h eastward current. Ocean currents are much slower than winds due to friction. WebDensity currents created by differences in water temperature and salinity When the air above water gets cold, what happens to water molecules? The molecules slow down and move closer together, increasing the water's density. What effect does evaporation of surface waters leaving solids behind have on the water in the ocean?

WebWhen a volume of water is cooled, the molecules move less vigorously so same number of molecules takes up less space and the water is denser. If salt is added to a volume of water, there are more molecules in the same volume so the water is denser. Changes in temperature and salinity of seawater take place at the surface.

Density currents circulate water … ear flapped hatsWebApr 29, 2008 · With water, colder and saltier equals denser. At the earth's poles, when water freezes, the salt doesn't necessarily freeze with it, so a large volume of dense cold, salt water is left behind. When this dense … earflap hats crochet patterns

"WebDo density currents move vertically or horizontally? Ocean currents are the continuous, predictable, directional movement of seawater driven by gravity, wind (Coriolis Effect), and water density. Ocean water moves in two directions: horizontally and vertically. Horizontal movements are referred to as currents, while vertical changes are called ... " - How do density currents move

WebEarth’s rotation is also responsible for the circular motion of ocean currents. There are 5 major gyres—expansive currents that span entire oceans—on Earth. There are gyres in the … WebPolarity is the current movement direction. Think of it like a metal spring. Compress the spring on a table and your movement will be down, remove the pressure and the spring pushes back up. Let's call that the resting state of the spring zero. Zero movement, zero current and voltage.

WebPlate tectonics refers to the movement of the rigid plates around the surface of Earth. The outer portion of the planet, or lithosphere, is relatively rigid because it is relatively cold. The lithosphere varies in thickness but is typically a hundred or so kilometers thick. It includes the upper mantle and both the continental and oceanic crust.
