What is warm and cold ocean currents?
They can be cold, warm, and hot. Warm ocean currents originate near the equator and move towards the poles or higher latitudes while cold currents originate near the poles or higher latitudes and move towards the tropics or lower latitudes. The current’s direction and speed depend on the shoreline and the ocean floor.
What is warm ocean currents?
Warm currents are those which flow away from the equatorial region and move towards the poles or latitudes which are on the western side of oceans basins. They bring warm waters in areas of cold water and are mainly observed in the eastern continents.
What are the two types of ocean currents?
There are two main types of ocean currents: currents driven mainly by wind and currents mainly driven by density differences. Density depends on temperature and salinity of the water.
Where do cold and warm currents meet?
Answer: The cold and warm ocean currents meet at the coast of Newfoundland.
What are ocean currents Class 9?
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.
What is the meaning of cold ocean current?
Cold ocean currents are large masses of cold water that move towards the equator, from a level of high altitude to lower levels. They absorb the heat they receive in the tropics, thereby cooling the air above them.
What do you mean by warm current?
A warm current is moving away from the Equator toward the poles. The water in a warm current is warmer than the surrounding water.
Which current is the coldest?
The Labrador Current is a cold current in the North Atlantic Ocean which flows from the Arctic Ocean south along the coast of Labrador and passes around Newfoundland, continuing south along the east coast of Canada near Nova Scotia.
What do cold currents and warm current together form?
The confluence of these two currents, one cold and the other warm, produce fog around the region and makes it the most important fishing ground in the world. The Gulf Stream then deflected eastward under the combined influence of the westerlies and the rotation of the earth.
What happens when warm and cold currents meet explain with example?
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.
What are warm currents Class 9?
The current which flows from warm tropical region to cooler temperate and polar region is called warm current and the current flowing from polar areas towards temperate and equational regions is called cold current, e.g. Gulf stream is a warm current and Labrador current is called cold current.
What are cold ocean currents and how are they formed?
Cold ocean currents are masses of cold water moving from high latitude towards the equator absorbing the heat received in the tropics thus cooling the air above. Cold currents are formed when the air circulating the eastern side of the subtropical high is blown over cold water mass and are then dragged toward the equator.
What is the difference between warm water and cold water currents?
Usually warm water has a higher salinity, but it remains less dense than cold water, so cold water is heavier and flows under warm water. The water is warmed on the surface, so warm currents flow across the surface of the ocean. As a warm current cools down, it drops down and becomes a cold water currents.
What are the ocean currents in the world?
The list of important ocean-wise currents is given below: Ocean Currents in Arctic Ocean Ocean Currents in Arctic Ocean Ocean Current Cold/Warm Baffin Island Current Cold Labrador Current Cold Ocean Currents in Atlantic Ocean Ocean Currents in Atlantic Ocean
How do ocean currents affect the weather?
Much larger currents are at work in our oceans, circulating water around the world. These ocean currents, which are massive currents that are influenced by a variety of different forces that act to propel the water both on the surface and in deep ocean waters. This movement has a significant effect on the earth’s weather.
