Ocean currents can be generated by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes. Currents may also be generated by density differences in water masses caused by temperature and salinity variations. These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them. Occasional events also trigger serious currents. Huge storms move water masses.urrents may also be generated by density differences in water masses caused by temperature and salinity variations.

Swirling Ocean Currents Help Spread Sea Life Puzzling clusters of microscopic plants in the ocean are likely caused by giant, swirling circular currents, scientists now reveal, providing a new view of how life travels around the globe. About half of the Earth's oxygen is generated by tiny, single-celled plants known as phytoplankton that live in the planet's oceans, rivers and lakes.

- The Role of Wind. Surface ocean currents are mainly caused by wind. The winds that most affect the oceans' currents are: The Role of Density. Differences in water density affect vertical ocean currents (movement of surface ocean water to the bottom of the ocean and movement of deep ocean water to the surface). Variations in water density are caused by variations in salinity (the amount of salt in water) and temperature.

- Surface ocean currents are also driven by an effect caused by Earth's rotation on its axis known as the Coriolis effect. The rotation of Earth acts to turn or deflect prevailing winds clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere, which deflects the surface currents.

Ocean current Wind-driven surface currents (such as the Gulf Stream) travel polewards from the equatorial Atlantic Ocean, cooling en route, and eventually sinking at high latitudes (forming North Atlantic Deep Water).

CONVECTIVE CURRENTS CONVECTIVE CURRENTS. Convective currents are a common cause of turbulence, especially at low altitudes. These currents are localized vertical air movements, both ascending and descending. For every rising current, there is a compensating downward current.

Ocean Currents and Climate The ocean has an interconnected current, or circulation, system powered by wind, tides, the Earth’s rotation (Coriolis effect), the sun (solar energy), and water density differences. The topography and shape of ocean basins and nearby landmasses also influence ocean currents.

What are the factors influencing ocean current circulation? The four factors that cause ocean currents: (1) Planet rotation, (2) Wind, (3) Density of the water (depends on temperature and salinity), and (4) Gravitation of the moon and earth. Direction and strength depends on the shape of the shoreline, depth and shape of the bottom, and other currents.

What causes convection currents in the earths mantle? Answer by Sarahroxoutofhersox1. Confidence votes 142. Convection currents are caused by the heat from the inner core. A layer in the mantle, called the asthenosphere, is fluid-like and is heated by the core, thus inducing convection currents to form.

- As these currents mix the oceans surface and deep waters, they help replenish the oxygen in the water. Other Causes of Currents. Other causes of currents include tides, rain, runoff, and ocean bottom topography. Topography is the surface features of a place.urface ocean currents are mainly caused by wind. The winds that most affect the oceans' currents are: The Role of Density. Differences in water density affect vertical ocean currents (movement of surface ocean water to the bottom of the ocean and movement of deep ocean water to the surface).

Currents Oceanic currents are driven by several factors. One is the rise and fall of the tides, which is driven by the gravitational attraction of the sun and moon on Earth's oceans. Tides create a current in the oceans, near the shore, and in bays and estuaries along the coast. These are called tidal currents..

How does the sun cause ocean currents? Merge this question into. Split and merge into it. Answer by Answers Publisher. Confidence votes 261K. The sun causes currents in the ocean because it is warming the water in the ocean in the day while it is hot, and then in the night when the sun goes down, the ocean starts to cool.

What Is The Atmosphere? The atmosphere is also responsible for the aurora borealis. Auroras are caused by the bombardment of solar electrons on oxygen and nitrogen atoms in the atmosphere. The electrons literally excite the oxygen and nitrogen atoms high in the atmosphere to create the beautiful light show we know as an aurora.

Ocean Currents The Types and Causes of Ocean Currents. In addition to their varying size and strength, ocean currents differ in type. They can be either surface or deep water. Surface currents are those found in the upper 400 meters (1,300 feet) of the ocean and make up about 10% of all the water in the ocean. Surface currents are mostly caused by the wind because it creates friction as it moves over the water. This friction then forces the water to move in a spiral pattern, creating gyres.

- What causes ocean currents? Ocean currents result from two processes-the action of wind on the surface of the water, and from variation in water temperature that causes movement-a process known as convection. Convection occurs because the oceanic waters heat up becoming less dense. This water moves above the cooler water, and give off its heat to the surrounding environment. As it cools, it begins to sink, and the process begins again. Convection results in the continual circulation of ocean water on a global scale.

Currents Winds drive ocean currents in the upper 100 meters of the ocean’s surface. However, ocean currents also flow thousands of meters below the surface. These deep-ocean currents are driven by differences in the water’s density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation.

What Causes Convection Currents in the Earth's Mantle? Quick Answer. Convection currents in Earth's mantle are caused by the rise of hot material rising towards the crust, becoming cooler and sinking back down. This process occurs repeatedly, causing the currents to constantly flow. The movement of the currents plays a factor in the movement of the mantle.

Currents Oceanic currents are driven by several factors. One is the rise and fall of the tides, which is driven by the gravitational attraction of the sun and moon on Earth's oceans. Tides create a current in the oceans, near the shore, and in bays and estuaries along the coast. These are called tidal currents.. Tidal currents are the only type of currents that change in a very regular pattern and can be predicted for future dates. A second factor that drives ocean currents is wind. Winds drive currents that are at or near the ocean's surface.

Ocean current Surface currents are found on the surface of an ocean, and are driven by large scale wind currents. They are directly affected by the wind—the Coriolis effect plays a role in their behaviors.
