What are deep currents cause 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.
What is responsible for deepwater currents?
Unlike the wind-driven surface currents, deep water currents are driven by differences in water density: heavier water sinks while lighter water rises. The main determinants of water density are temperature and salt concentration; thus, the deep currents are thermohaline (temperature- and salt-driven) currents.
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.
Why are there deep 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 directly influences Deepwater currents quizlet?
Deepwater currents are dependent on temperature and salinity.
What causes cold deep currents to form in the ocean?
What causes deep, cold currents to form in the oceans near the poles? The sinking of dense, cold water paired with high salinity.
What is responsible for deepwater currents quizlet?
Surface currents are caused by wind; deepwater currents are caused by differences in water density.
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.
What are the three factors that control deep currents?
What are three factors that control deep currents? Density, salinity, and temperature; accept also the Coriolis effect.
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.
Where do deep ocean currents begin?

What is the driving force of the deep water ocean conveyor belt?
The global ocean conveyor belt is a constantly moving system of deep-ocean circulation driven by temperature and salinity.
Which of the following factors influences ocean currents?
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.
What causes surface currents and deep currents quizlet?
Surface currents occur at the surface of the ocean and are caused by global winds; the Gulf Stream is an example. Deep currents occur deep in the ocean and are influenced by water density, salinity, and temperature.
How are surface ocean currents driven quizlet?
Surface currents in the ocean are primarily driven by the wind. a ring-like system of ocean currents rotating clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere caused by the Coriolis Effect.
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 makes ocean currents move?
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 upwellings or downwellings.
What two factors contribute to the formation of deep sea currents?
Deep currents are driven by temperature and water density/salinity.
What are 4 factors that drive ocean currents?
Four Factors That Create Ocean Currents
- Wind. Wind is the single biggest factor in the creation of surface currents. …
- Water Density. Another major factor in the creation of currents is water density, caused by the amount of salt in a body of water, and its temperature. …
- Ocean Bottom Topography. …
- Coriolis Effect.

What is the primary force that drives ocean waves?
What is the primary force that drives ocean waves? Waves are most commonly caused by wind. Wind-driven waves or surface waves are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake the continual disturbance creates a wave crest.
What causes deep 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 drives deep ocean circulation upwelling or downwelling?
Cooling or evaporation of fresh water from the sea surface makes surface water dense and causes it to sink. Downwelling of cold, dense water drives thermohaline circulation. Upwelling takes place at some coastlines or along the Equator and brings cool, nutrient-rich water to the surface.
What factors create deep ocean currents quizlet?
What are three factors that control deep currents? Density, salinity, and temperature; accept also the Coriolis effect.
How does water move in the deep ocean?
Deep ocean currents may move across great horizontal distances in the same way as surface currents. They also may run through the ocean vertically, although vertical currents are weak, and a body of water may take centuries to go from the surface to the bottom, Generally, the deeper a current, the more slowly it moves.
What are three factors that control deep currents?
What are three factors that control deep currents? Density, salinity, and temperature; accept also the Coriolis effect.
What are two main factors that influence ocean currents?
Oceanic currents are driven by three main factors:
- The rise and fall of the tides. Tides create a current in the oceans, which are strongest near the shore, and in bays and estuaries along the coast. …
- Wind. Winds drive currents that are at or near the ocean's surface. …
- Thermohaline circulation.

What is the driving force behind winds and currents?
What is the driving force of ocean currents and atmospheric movement quizlet? The sun is the driving force of oceanic and atmospheric circulations. It heat the earth unevenly causing convection currents in the air and ocean.
What causes surface currents and deep currents?
Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth's rotation, and the position of landforms that interact with the currents. Surface wind-driven currents generate upwelling currents in conjunction with landforms, creating deepwater currents.
What causes upwelling currents?
Winds blowing across the ocean surface often push water away from an area. When this occurs, water rises up from beneath the surface to replace the diverging surface water. This process is known as upwelling.
What causes currents to flow?
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.
