What factors are responsible for the origin of ocean currents how do they influence regional climate fishing and navigation?

What are the factors responsible for the origin of 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.

Which factors impact the ocean currents formation and how do they influence climate in different regions of the world?

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

How do ocean currents influence regional climate fishing and navigation?

The ocean currents are very important in determining the climates of different regions of the world, especially those regions bordering on the ocean. … Precipitation: Warm currents flow along the east coast of continents resulting in warm and rainy climates while cold currents flow along the west coast of continents.

What are the main factors responsible for 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.

How do ocean currents affect climate Class 9?

The ocean currents greatly influence the temperature of an area. In areas where warm and cold currents meet, the temperature falls, giving rise to foggy conditions. Whoever, mixing of warm and cold currents supports a rich marine life.

How do ocean currents affect climate quizlet?

A warm ocean current that flows toward the poles results in warm air masses that move over land that the current flows past. This causes the climate of that land area to be warmer than it would be otherwise. A cold ocean current that flows toward the equator results in cold air masses affecting the nearby land.

Which of the above factors influence ocean currents?

Which of the above factors influence the ocean currents? An ocean current is a continuous, directed movement of seawater. The Rotation of Earth (Coriolis Force), forces acting via winds, temperature and salinity differences influence the ocean currents. The correct option is B.

How do ocean currents influence fishing?

Ocean currents are important in the fishing industry as they affect the growth of plankton which provides fish food. Warm ocean currents restrict the growth of plankton hence give rise to poor fishing grounds. … These give rise to rich fishing grounds.

What three factors affect global ocean currents briefly explain how each factor affects ocean currents?

Surface currents are controlled by three factors: global winds, the Coriolis effect, and continental deflections. surface create surface currents in the ocean. Different winds cause currents to flow in different directions. objects from a straight path due to the Earth’s rotation.

How do ocean currents influence navigation?

Winds, water density, and tides all drive ocean currents. Coastal and sea floor features influence their location, direction, and speed. … This phenomenon causes ocean currents in the Northern Hemisphere to veer to the right and in the Southern Hemisphere to the left.
