What are the effects of currents?
Effects of Ocean Currents Ocean currents regulate the Earth’s climate and make up for the difference in solar energy radiation hitting the surface of the planet.
As such, water current distributes heat.
The ocean absorbs most of the sun’s radiation on Earth, in contrast to the atmosphere and to land..
What are the causes of currents?
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 if ocean currents stop?
If it continues to slow, that could have profound consequences for Earth’s inhabitants. Studies suggest it would mean much colder winters and hotter summers in Europe, changing rainfall patterns in the tropics, and warmer water building up along the U.S. coast that can fuel sea level rise and destructive storms.
What are the 3 major ocean currents?

What are the 5 major ocean currents?
There are five major gyres: the North and South Pacific Subtropical Gyres, the North and South Atlantic Subtropical Gyres, and the Indian Ocean Subtropical Gyre.
What do surface currents affect?
Surface ocean currents carry heat from place to place in the Earth system. This affects regional climates. The Sun warms water at the equator more than it does at the high latitude polar regions. The heat travels in surface currents to higher latitudes.
How are ocean currents useful to us?
By moving heat from the equator toward the poles, ocean currents play an important role in controlling the climate. Ocean currents are also critically important to sea life. They carry nutrients and food to organisms that live permanently attached in one place, and carry reproductive cells and ocean life to new places.
What causes the Coriolis effect?
The Coriolis effect describes the pattern of deflection taken by objects not firmly connected to the ground as they travel long distances around Earth. … The key to the Coriolis effect lies in Earth’s rotation. Specifically, Earth rotates faster at the Equator than it does at the poles.
Are surface currents warm or cold?
Cold surface currents come from polar and temperate latitudes, and they tend to flow towards the equator. Similar to warm surface currents, cold surface currents are driven mainly by atmospheric forces and are influenced by the earth’s rotation.
What are the effects of ocean currents on Earth?
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 major surface currents?
Surface currents are created by three things: global wind patterns….Global Wind Patternstrade winds: east to west between the Equator and 30oN and 30oS.westerlies: west to east in the middle latitudes.polar easterlies: east to west between 50o and 60o north and south of the Equator and the north and south pole.
What are 3 things that affect surface currents?
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. objects from a straight path due to the Earth’s rotation.
How do currents work?
Ocean currents are driven by a range of sources: the wind, tides, changes in water density, and the rotation of the Earth. The topography of the ocean floor and the shoreline modifies those motions, causing currents to speed up, slow down, or change direction.
Why are surface currents important?
Surface currents are created by three things: global wind patterns, the rotation of the Earth, and the shape of the ocean basins. Surface currents are extremely important because they distribute heat around the planet and are a major factor influencing climate around the globe.
