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

Ocean currents are driven by surface winds, Earth’s rotation, and differences in salinity. Trade winds blow warm surface waters in tropical oceans and seas from east to west. Warm water pools along the west coast of continents, which sets up a temperature gradient across the ocean surface.

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.

Which factors impact the ocean currents formation?

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.

How do ocean currents affect climate of different areas?

Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate. … Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.

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?

Ocean currents can be generated by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes.

What are the effects of ocean currents?

Effects of Ocean Currents

  • They result in rain. Warm currents lead to evaporation, which turns into the rain for the coastal areas. …
  • They can also cause deserts. …
  • They can destroy marine wildlife. …
  • They help with the continuity of life. …
  • They save up on time and costs. …
  • They can result in deaths.

How do ocean currents influence the climate and economic activities of any area?

Ocean currents influence the climate and economic activities of coastal regions in the following ways: Warm currents raise the temperature along the coast, while cold currents drop the temperature along the coast. … Winds blowing over warm currents result in a good amount of rainfall, as they get moisture-laden.

How do ocean currents affect climate Upsc?

Warm ocean currents bring rains to the coastal regions and also the interiors while cold currents do not. Warm currents flow along the east coast of continents in tropical and sub-tropical latitudes resulting in warm and rainy climates while cold currents flow along the west coast of continents.

How do ocean currents affect climate quizlet?

Ocean currents affect world climate because ocean currents carry warm water, which helps warm climates of land masses.

How do ocean currents affect climate Class 9?

Complete answer: Sea currents have a strong influence on the earth’s climate. … This heat is transported by nautical currents. Therefore, ocean currents play a significant role in regulating the Earth’s climate by facilitating the transfer of heat from warm tropical areas to colder areas near the poles.

How do ocean currents influence climate in the coastal areas Class 7?

Answer: Ocean currents influence the climate and economic activities of coastal regions in the following ways: Warm currents raise the temperature along the coast, while cold currents drop the temperature along the coast. … On the other hand, winds blowing over cold currents are dry; therefore, rainfall is scanty.

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.
