Best answer: What are the factors responsible for ocean current formation how do they influence climate in different regions of the world?

What are the factors responsible for ocean current formation .how do they influence climate in different regions of the world?

Earth rotation and gravity: The rotation of the Earth causes Coriolis force which affects the direction of movement of water and leads to formation of ocean currents. … Temperature difference: Cold-water ocean currents occur when the cold water at the poles sinks and slowly moves towards the equator.

What factors are responsible for formation of ocean current?

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.

What are 4 factors that cause ocean currents?

There are four factors affecting the origin and flow of Ocean Currents i.e. Rotation and gravitational force of the Earth; Oceanic factors (temperature, salinity, density, pressure gradient and melting of ice); atmospheric factors (atmospheric pressure, winds, rainfall, evaporation and insolation); factors that …

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.

What are the forces that influence the current?

primary forces that initiate the movement of water; secondary forces that influence the currents to flow.

The primary forces that influence the currents are:

  • heating by solar energy;
  • wind;
  • gravity;
  • Coriolis force.

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.

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.

How do ocean currents influence climate provide at least three examples?

Ocean currents influence climate because the currents are major redistributors of heat and energy throughout the globe. Warm currents such as the Gulf Stream cause regions that would normally be cold to be warmer. For example, New York is warm for its latitude. … Cold currents also increase the aridity of an area.

How does the ocean influence weather?

The ocean influences weather patterns by distributing heat and moisture around the globe. … Warm water is also evaporated from the ocean into the atmosphere, where it can condense and form clouds, which can eventually lead to rain.
