How do deep ocean currents form?
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.
What are three ways that deep currents form?
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. Currents are cohesive streams of seawater that circulate through the ocean.
How do deep currents form quizlet?
Deep currents form because of density differences. Dense water sinks to the bottom of the ocean and forms deep currents.
What are the factors of deep currents?
Deep ocean currents are density-driven and differ from surface currents in scale, speed, and energy. Water density is affected by the temperature, salinity (saltiness), and depth of the water. The colder and saltier the ocean water, the denser it is.
Where do deep currents occur?
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.
Where do deep ocean currents begin?

What is responsible for deepwater currents?
Surface wind-driven currents generate upwelling currents in conjunction with landforms, creating deepwater currents. Currents may also be caused by density differences in water masses due to temperature (thermo) and salinity (haline) variations via a process known as thermohaline circulation.
What causes deep ocean currents 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 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.
What do deep currents do?
Downwelling can take place in other places where surface water becomes very dense (Figure below). Deep currents flow because of differences in density of ocean water. When water sinks it pushes deep water along at the bottom of the ocean. This water circulates through all of the ocean basins in deep currents.
Where do ocean currents form?
Where the air sinks, some travels towards the pole and some air travels towards the equator. This air motion creates strong winds flowing from the west (“westerlies”, see below) and the northeast (trade winds, see below) in the Northern Hemisphere. These dominant wind patterns drive oceanic currents (see below).
Which is one characteristics of deep ocean currents?
What is one characteristic of deep ocean currents? Deep ocean currents move cold water toward the equator.
How are deep currents different from surface currents give two ways?
Deep currents are driven by temperature and water density/salinity. Of course, deep currents impact surface currents, which carry warm water to the poles. Surface currents are also driven by global wind systems fueled by energy from the sun. Factors like wind direction and the Coriolis effect play a role.
How deep do surface currents go?
50 to 100 meters deep These are winds that drive the system of surface currents in the ocean. Surface currents are only 50 to 100 meters deep (Table 3.1). Though shallow, they are extremely important in determining the world's weather and climates, and in distributing the ocean's heat and nutrients.
