What forces are responsible for the movement of ocean water in currents What forces and factors influence the direction and nature of ocean currents?

Primary forces are thermal expansion and contraction of water, the stress of wind blowing over the water, and density differences between water layers. Secondary forces and factors are the Coriolis Effect, gravity, friction, and the shape of the ocean basins themselves.

What forces are responsible for the movement of ocean water in currents quizlet?

Temperature and salinity both influence the movement of water in deep-ocean currents.

What forces are responsible for the movement of ocean water in currents?

Tides contribute to coastal currents that travel short distances. Major surface ocean currents in the open ocean, however, are set in motion by the wind, which drags on the surface of the water as it blows. The water starts flowing in the same direction as the wind. But currents do not simply track the wind.

Which of the following factors does not cause ocean currents?

• Prevailing winds.
• Rotation of the earth.
• Revolution of the earth.
• Temperature differences.

Which factors affect the movement of ocean currents select the three?

The factors that affect movement of the ocean currents include the rotation of Earth, variations in water temperature, pressure gradient, and wind.

Which factors affect the movement 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.

What can stop ocean currents?

More warm surface water flows in to take its place, cools, sinks, and the pattern continues. However, melting Arctic sea ice and melting Greenland glaciers could change this pattern of ocean currents, or stop it altogether. Recent research shows that Arctic sea ice is melting due to climate warming.

What are the reasons responsible for the formation of deep ocean currents Class 8?

Answer. 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.
