How do ocean currents influence the climate of a place Class 7?

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. … When water molecules are heated, they exchange freely with the air in a process called evaporation.

How does ocean currents affect climate class 7?

1. The ocean currents carry cold water from the polar regions to equatorial regions. 2. The winds blowing over warm currents are moisture-laden and, thus, cause rainfall in the coastal areas.

How do oceanic current influence climate explain with example?

Ocean currents are caused by the uneven heating of the Earth surface. … Warm ocean currents increases the temperature of the near by coastal areas while cold ocean currents bring down the temperature. For example, the warm North Atlantic Drift keeps the temperature of Western Europe warm even during winters.

How do ocean currents affect climate Class 5?

As the horizontal currents are moving south or northwards, they carry with them cool or warm water over an extended distance. It is the displaced water that affects the air, by warming or cooling it, thereby transferring the same effect to the land surface over which it blows. This is how ocean currents affect climate.

What effect do the ocean currents have on the climate of a place Class 9?

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

What are ocean currents answer class 7th?

Ocean currents are streams of water flowing constantly on the ocean’s surface in definite directions. They are caused by differences in the temperature and salinity of water, by wind, solar heating and gravity. The winds majorly responsible for creating ocean currents are the Westerlies and the Trade winds.

How do currents influence the 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.

How does a sea or an ocean influence the climate of a place?

The oceans influence climate by absorbing solar radiation and releasing heat needed to drive the atmospheric circulation, by releasing aerosols that influence cloud cover, by emitting most of the water that falls on land as rain, by absorbing carbon dioxide from the atmosphere and storing it for years to millions of …

What are ocean currents discuss the influence of ocean currents?

Ocean currents are similar to winds in the atmosphere in that they transfer significant amounts of heat from Earth’s equatorial areas to the poles and thus play important roles in determining the climates of coastal regions. In addition, ocean currents and atmospheric circulation influence one another.

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 coastal region?

Ocean currents influence the temperature of the region they travel through. Warm currents increase the temperature of the coasts along which they move. Sea breezes that blow over warm currents get warmed in turn and absorb moisture. Then they carry the warmth and moisture to neighboring coastal areas.

How does ocean currents affect the climate of South Africa?

The Agulhas Current transports warm tropical Indian Ocean water southwards along the South African coast. It modulates the rainfall along the east coast and interior regions of South Africa by providing the latent heat of evaporation needed for onshore wind systems to pick up moisture and carry it inland.

How does an ocean currents influence the rainfall distribution?

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.

How do ocean currents influence the climate and economic activities of the coastal regions?

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 currents What causes these currents in geography?

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. Currents are cohesive streams of seawater that circulate through the ocean.

What happens when warm and cold ocean currents meet?

This is because air above the warm currents is warm which contains water vapour. When this warm current meet the cold current, the air above the cold current, causes the water vapour of the warm current to condense into tiny particles which form fog.
