Ocean currents are large systems of water that flow in defined patterns around the world's oceans. These currents play a vital role in the global climate, as they help to distribute heat around the planet and can have a significant impact on weather patterns. There are several different types of ocean currents, including surface currents, which flow near the top of the ocean, and deep water currents, which flow at greater depths.

One of the most well-known ocean currents is the Gulf Stream, which begins in the Gulf of Mexico and flows northward along the eastern coast of the United States before crossing the Atlantic Ocean. The Gulf Stream is a warm current that helps to moderate the climate in Europe, making it milder than it would be otherwise.

Another important ocean current is the Kuroshio Current, which flows from the Philippines towards Japan. This current is also warm and helps to keep the climate in Japan mild. The Agulhas Current is another significant current, flowing from the Indian Ocean towards the southern coast of Africa. This current is responsible for bringing warm, moist air to the region, which can lead to heavy rainfall.

There are several factors that can influence the movement of ocean currents. One of the most important is the temperature of the water, as warm water is less dense than cold water and therefore tends to rise to the surface. This can cause the formation of surface currents, such as the Gulf Stream and the Kuroshio Current.

The movement of ocean currents is also influenced by the Earth's rotation, which causes the currents to curve to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This is known as the Coriolis Effect.

In addition to their impact on climate and weather, ocean currents also play a crucial role in the global ecosystem. They help to distribute nutrients and support the growth of marine life, and they also affect the migration patterns of marine animals.

Overall, the movement of ocean currents is a complex and vital process that plays a significant role in the global climate and ecosystem. Understanding these currents and their movement is an important part of understanding the Earth's climate and predicting future weather patterns.

They also occur twice in a month- during the first quarter moon and the last quarter moon. And this is makes the ocean water become hotter. Especially, for the last of coral reef that is so fragile and sensitive about its surrounding. Firstly polar water is cold and because of less amount of good intensity light, it goes under contraction. The importance of ocean currents Ocean currents hold an important part in the survival and distribution of species across the globe. There are some types of meteorological condition about the tides. Under the effect of Coriolis, force westerlies turn to the northeast direction and trade winds turn to southwest direction.

Invite volunteers to read each caption aloud as you scroll through the gallery.  Image source — NCERT Tides  Tides are the periodical rise and fall of the ocean levels once or twice a day mainly due to the gravitational forces exerted by the sun, the moon and the rotation of the earth. Writer Naomi Friedman, M. It splits into two branches — one moves south around Cape Horn into the Atlantic Ocean and the other one moves northwards along the Peruvian coast and joins the Peru current. A simple example is an aquarium. Due to Coriolis force wind and water gets deflected right in the N. Tides Different name different movement.

Deep Ocean Currents deep water currents are triggered by density differences. It is the layer of the ocean water which moves due to the stress of blowing the wind and this motion is thus called as Ekman Transport. These two case studies will give you an insight into the power and the complexity of the oceanic currents and their interaction with the dropped by-products of our civilization. Due to Coriolis force the wind which had risen in the north instead of going into the straight-line turn right in the northern hemisphere. Have students mark 44N, 178E on their maps. Major Ocean Currents The oceanic circulation transports heat from one latitude belt to another in a manner similar to the heat transported by the general circulation of the atmosphere. The tides during this period will be lower than the normal which are called as the neap tides.

This happens once in a month. Because of no obstruction on way as well as almost circular shape of Antarctica, west wind drift encircles it. Once the oil was inside the current system, it was carried along the coast for hundreds of miles. This creates a sloping condition that sets off water flow from equator to poles. As a result, nearly 11 million gallons 35,000 metric tons of crude oil leaked out into the water over several days. Some ocean currents are warm and some are cold, as indicated by the red and blue arrows on the map.

Moscow Department of Gidrometeoizdat in Mandarin : 125—9. Aphelion: It is the position where the earth is farthest from the sun around July 4 th. The same storm systems bringing abundant precipitation are also responsible for winds that create coastal convergences in the ocean and the downwelling of the surface waters. The short would be — ocean circulations. Oyashio Current is a cold current that originates from the north pole and it mixes with Kuroshio current which is a warm current. The Indian rivers like the Ganges, Brahmaputra, Indus, etc exhibits tidal bores. Stream — Streams are larger masses of water moving in a definite direction and have much greater velocity than the drifts.

The surface layer is a lot warmer than the layer near the bottom. Divide students into six small groups. It flows in the western boundary of the ocean basin and eastern boundary of the continent. As a result surface water sinks in towards the bottom. It is an easterly moving drift in the Pacific Ocean extending from Tasmania to the South American coast.

Scientists across the globe are trying to figure out why the ocean is becoming more violent and what, if anything, can be done about it. Due to this fact Rip, currents are so deadly and carried to far beyond the shore. Show the Ocean Conveyor Belt cartoon from the Resource Carousel again and discuss how differences in water temperature relate to the Ocean Conveyor Belt. Unusual high and low tides occur during this time. Unusual high and low tides occur during this time.

Water particles only travel in a small circle as a wave passes. It is a cold current which flows along the west coast of South America towards the north. This happens normally after seven days of a spring tide. Retrieved 7 January 2021. The tides will move up and down or we also know it as the rise and fall of ocean water because of the gravity.
