What are the factors that influence 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 factors that influence ocean currents Class 7?

Following are the four important factors that give rise to ocean currents or modify their course:

• Rotation of the Earth.
• The shapes of the coastlines.
• Effects of planetary winds on the ocean surface.
• Difference in the density of ocean water due to variations in temperature and salinity.

What are five factors that affect ocean current flow?

The ocean has an interconnected current, or circulation, system powered by wind, tides, the Earth’s rotation (Coriolis effect), the sun (solar energy), and water density differences. The topography and shape of ocean basins and nearby landmasses also influence ocean currents.

What are the two main factors that affect deep ocean currents?

Deep currents are driven by temperature and water density/salinity.

What are the factors that generate the ocean currents 9th standard?

The factors that generate ocean currents are:

• Earth’s rotation.
• Prevailing winds and.
• Differences in temperature and salinity of ocean water.

What are the three effects of ocean currents?

Answer

• it plays an important role in influencing the climate of the coastal regions of continents.
• it raises the temperature and makes the place warmer than the surrounding areas.
• warm ocean currents causes rainfall.

What are the 5 major ocean currents?

There are five major ocean-wide gyres—the North Atlantic, South Atlantic, North Pacific, South Pacific, and Indian Ocean gyres. Each is flanked by a strong and narrow “western boundary current,” and a weak and broad “eastern boundary current” (Ross, 1995).

What are six factors that affect the direction and speed of ocean currents?

What are the three major effect of current?

Hence, the three effects of electric current are heating effect, magnetic effect and chemical effect.

What are four factors cause 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.

Which two factors largely influence ocean currents?

The two factors that largely influence ocean currents is the height of waves and the rotation of earth. They greatly affect the ocean currents. Hope this helps answer your question and have a nice day ahead.

What are the causes and effects of ocean currents?

Wind, temperature differences, water density and salinity all play a role in generating ocean currents. Currents may also be influenced by external forces, such as earthquakes, the coriolis effect produced by the Earth’s rotation, and the gravitational pull of the Moon.

Which of the following factors influences ocean currents?

There are many factors that influence ocean currents, four of the factors would be planet rotation, wind, density of water, and gravitation. Planet rotation causes the currents to move clockwise in the northern hemisphere and counter clockwise in the southern hemisphere.
