What are the factors that effects ocean currents?

What are the factors that effects ocean currents?

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.

What 4 factors affect 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 3 factors affect major ocean surface currents?

B. 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.

What causes ocean currents quizlet?

A directional movement of ocean water; surface currents result from steady winds over the ocean surface; deep ocean currents result from density variations due to temperature and salinity differences.

What are ocean currents 7?

Ocean currents are streams of water flowing constantly on the ocean surface in definite directions. The ocean currents may be warm or cold. The warm ocean currents originate near the equator and move towards the poles. The ocean current influences the temperature conditions of the area.

Which factors affect the movement of ocean currents Brainly?

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

What are the causes and effects of 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 factors affect the path of an ocean current quizlet?

Ocean currents, which are the ocean water’s movement in a particular direction, are mainly influenced by factors such as wind patterns, temperature, water density, salinity, shape of the ocean basin, and gravity.

What is the effect of ocean currents on climate?

Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface.

What are the advantages and disadvantages of ocean currents?

Advantage: The areas where the warm and cold currents meet provide the best fishing grounds of the world. Disadvantage: The areas where a warm and cold current meet also experience foggy weather making it difficult for navigation.

What are the main effects of ocean currents Class 7?

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.

What are four factors cause ocean currents?

Trade Winds. Trade winds are the winds that blow in the direction from east to west.

  • Westerlies. Westerlies are winds that are similar to the Trade winds.
  • Coriolis Forces.
  • Landform Position.
  • Density Differences.
  • Temperature.
  • Salinity of ocean water.
  • Ocean Storms.
  • Underwater Earthquake.
  • Gulf Stream Wind.

    Major causes of ocean currents include wind friction, gravity, and variation in water density in different parts of the ocean. Surface ocean currents are mainly caused by wind. The winds that most affect the oceans’ currents are: The Westerlies (40-50 degree latitudes) blow west to east.

    How does the gravity affect ocean currents?

    Finally, gravity plays a role in the movement of surface currents because the top of the ocean is uneven. Mounds in the water form in areas where the water meets land, where water is warmer, or where two currents converge. Gravity then pushes this water downslope on the mounds and creates currents.
