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. ... These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them.
How do ocean currents and water transport?
Water cools as it moves from the equator to the poles via surface currents. ... As a result, the surface currents and the deep currents are linked. Wind causes surface currents to transport water around the oceans, while density differences cause deep currents to return that water back around the globe (Figure 14.17).
What is an ocean current and how do they move?
Ocean currents are the continuous, predictable, directional movement of seawater driven by gravity, wind (Coriolis Effect
What are the 3 major ocean currents?
The produce large circular currents in all the ocean basins. Currents, The North Equatorial Current, the Gulf Stream, the North Atlantic Current, and the Canary Current .
How do currents move in the ocean?
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. ... These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them.
What are the 5 major ocean currents?
Ocean gyres are large system of circular ocean currents formed by global wind patterns and forces created by Earth’s rotation. The five major circulation patterns formed by the currents on this map are the world’s five major ocean gyres: North Atlantic, South Atlantic, Indian, North Pacific, and South Pacific .
What are the major ocean currents?
There are five major gyres: the North Atlantic, the South Atlantic, the North Pacific, the South Pacific and the Indian Ocean Gyre , see figure 1. The Antarctic Circumpolar Current is situated in the Southern Ocean and constantly circles around Antarctica because there are no land masses to interrupt the currents.
What are the two types of ocean currents give examples?
Two major kinds of currents define the planet’s oceans: surface currents driven by wind and deep-water currents driven by variations in seawater density .
How fast do ocean currents move?
Horizontal movements are called currents, which range in magnitude from a few centimetres per second to as much as 4 metres (about 13 feet) per second. A characteristic surface speed is about 5 to 50 cm (about 2 to 20 inches) per second .
Why is ocean water always saline?
Salt in the sea, or ocean salinity, is mainly caused by rain washing mineral ions from the land into water . Carbon dioxide in the air dissolves into rainwater, making it slightly acidic. ... Sodium and chloride, the main constituents of the type of salt used in cooking, make up over 90% of all the ions found in seawater.
Where are the strongest ocean currents?
The strongest and most renown surface ocean currents are the Gulf Stream , that travels from the Caribbean Sea, along the East coast of North America and across the Atlantic Ocean to Europe, and the Kuroshio Current in the North Pacific Ocean off the East coast of Asia.
Which current is the coldest?

Which ocean current is the strongest and fastest ocean current in the world?
Gulf Stream Velocity . The Gulf Stream is the fastest ocean current in the world with peak velocities near 2m/s. Shown to the left are velocity profiles across the Gulf Stream at the Straits of Florida and Cape Hatteras. In both sections the Gulf Stream is flowing into the page.
What are effects of ocean currents?
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 is another name for ocean currents?
| current deep current | marine current ocean circulation | thermohaline circulation |

What are the two major ocean currents?
The two basic types of currents – surface and deep-water currents – help define the character and flow of ocean waters across the planet.
