What affects deep ocean currents?

What affects deep ocean currents?

Winds, water density, and tides all drive ocean currents. Coastal and sea floor features influence their location, direction, and speed. Earth’s rotation results in the Coriolis effect which also influences ocean currents.

What are the three things that cause deep 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 are the two major controlling factors for deep ocean currents?

Deep-water Currents Instead of airflow, these currents primarily arise from variations in the density of seawater, controlled by its temperature and salt content (salinity).

What are the reasons responsible for the formation of deep ocean currents?

Deep ocean currents (also known as Thermohaline Circulation) are caused by:

• The density of sea water varies globally due to differences in temperature and salinity. Surface water is heated by the sun, and warm water is less dense than cold water.
• The earth’s rotation also influences deep ocean currents.

What force drives deep ocean currents?

These deep-ocean currents are driven by differences in the water’s density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation. In the Earth’s polar regions ocean water gets very cold, forming sea ice.

What are the 4 factors that create 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 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 the reasons responsible for the formation of deep ocean currents Class 8?

The difference in temperatures of various parts of the ocean is the major reason behind the deep-sea currents. Warm water has lower salinity and density. Such water comes to the surface of the sea. Cold water with high density goes down.

What factors cause ocean water to become denser?

The two main factors that affect density of ocean water are the temperature of the water and the salinity of the water. The density of ocean water continuously increases with decreasing temperature until the water freezes.

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 .

What are the reasons responsible for the formation of deep ocean current?

Deep ocean currents are driven by density and temperature gradients. Because the movement of deep water inocean basins is caused by density-driven forces and gravity,deep waters sink into deep ocean basins at high latitudes where the temperatures are cold enough to cause the density to increase.

What are the four factors that affect ocean currents?

Factors related to the earth’s rotation: Gravitational force and force of deflection. ADVERTISEMENTS:

Factors originating within the sea: Atmospheric pressure,winds,precipitation,evaporation and insolation.

Factors originating within the sea: Pressure gradient,temperature difference,salinity,density and melting of ice.

What are the causes and effects of ocean currents?

Major causes of ocean currents include wind friction, gravity, and variation in water density in different parts of the ocean. Surface ocean currents are mainly caused by wind. The winds that most affect the oceans’ currents are: The Westerlies (40-50 degree latitudes) blow west to east.

What force drives the ocean currents?

The two forces which primarily drive the deep ocean current are temperature and salinity.
