What are deep-ocean currents caused by?

In contrast to wind-driven surface currents, deep-ocean currents are caused by differences in water density. The process that creates deep currents is called thermohaline circulation—“thermo” referring to temperature and “haline” to saltiness.

Are deep ocean currents caused by convection?

Convection also plays a role in the movement of deep ocean waters and contributes to oceanic currents. Inside Earth, the convection of mantle material is thought to cause the movement of the overriding crustal plates, resulting in events such as earthquakes and volcanic eruptions.

What causes deep ocean currents to form quizlet?

What causes deep water currents to move? It is caused by temperature and salinity of the water. It is from the surface to 200m deep. It is caused by wind action, Earth's spin, and the shape of the continents.

What is a deep current?

Deep currents, also known as thermohaline circulation, result from differences in water density. These currents occur when cold, dense water at the poles sinks. Surface water flows to replace sinking water, causing a conveyor belt-like effect of water circulating around the globe on a 1000-year journey.

What causes deep water currents apex?

What causes deep water currents apex? ... The sinking and transport of large masses of cool water gives rise to the thermohaline circulation, which is driven by density gradients due to variations in temperature and salinity.

What are the 3 major ocean currents?

The produce large circular currents in all the ocean basins. Currents, The North Equatorial Current, the Gulf Stream, the North Atlantic Current, and the Canary Current.

What are surface currents caused by?

Surface currents are created by three things: global wind patterns, the rotation of the Earth, and the shape of the ocean basins. Surface currents are extremely important because they distribute heat around the planet and are a major factor influencing climate around the globe.

What are deep currents quizlet?

Deep currents. A measure of dissolved salts or solids in a solid. Salinity. The movement of deep, cold& nutrient rich water from the deep ocean rises to the surface & replaces warm surface water. Upwelling.

Which of the following explains why deep ocean currents form?

Deep currents are formed when the density of the water changes due to temperature and salinity. These currents mix the ocean water by moving the cold water toward the equator and the warm water toward the poles. ... They mix the ocean water by moving the cold water toward the equator and the warm water toward the poles.

What are the two causes of density in deep current waters?

deep currents. surface currents. What are the two causes of density in deep current waters? ... Oxygen content of the water and high temperatures .

How do deep currents affect the oceans?

Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.

What is the deep ocean current called?

Deep ocean currents

This process is known as thermohaline circulation. In cold regions, such as the North Atlantic Ocean, ocean water loses heat to the atmosphere and becomes cold and dense.

Where do deep ocean currents form?

Thus, deep currents generally occur in the higher latitude regions of the Earth, such as North Atlantic Deep Water and Antarctic Bottom Water, and from these frigid poleward regions the deep currents flow at a relatively slow pace towards the equator.

What causes deep water currents answers?

Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. ... Surface wind-driven currents generate upwelling currents in conjunction with landforms, creating deepwater currents.

How are deep water currents formed at poles?

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 water sinks to the ocean floor, more water moves in to replace it, creating a current.

Why is deep water current important?

Deep water currents return nutrients to the surface by a process known as upwelling. Upwelling brings nutrients back into sunlight, where plankton can use the nutrients to provide energy that drives an ocean's ecosystem.
