Ocean currents can be generated by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes. Additionally, the surface currents may be very different than currents at depth, which can make launching and recovering submersibles an even greater challenge. Surface currents are generated largely by wind. Their patterns are determined by wind direction, Coriolis forces from the Earth’s rotation, and the position of landforms that interact with the currents. Surface wind-driven currents generate upwelling currents in conjunction with landforms, creating deepwater currents.

What Causes Deep Ocean Currents? Quick Answer. Deep ocean currents are caused by density differences in the water, which are typically due to variations in salinity and temperature. Deep ocean currents are those found below 1,312 feet (400 meters). They are also known as thermohaline circulation and make up approximately 90 percent of the ocean. Continue Reading

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 are cohesive streams of seawater that circulate through the ocean.urrents 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.

convection Current in a fluid caused by uneven distribution of heat. For example, air on a part of the Earth's surface warmed by strong sunlight will be heated by contact with the ground and will expand and flow upward, creating a region of low pressure below it; cooler surrounding air will then flow in to this low pressure region.

Currents Open ocean currents are minimally influenced by tides. They flow in complex patterns affected by wind, the water’s salinity temperature, and Earth's rotation. In essence, open ocean currents are the steady flow of surface ocean water in a prevailing direction.

- Surface water movement takes place in the form of currents. Currents move ocean water horizontally at the ocean's surface. Surface currents are driven mainly by the wind. Other forces such as the Coriolis effect and the location of landmasses do affect surface current patterns.

Ocean Currents Mounds in the water form in areas where the water meets land, where water is warmer, or where two currents converge. Gravity then pushes this water down slope on the mounds and creates currents. Deep water currents, also called thermohaline circulation, are found below 400 meters and make up about 90% of the ocean. Like surface currents, gravity plays a role in the creation of deep water currents but these are mainly caused by density differences in the water.

What Causes Global Wind Patterns? This moving air creates oceanic surface currents that moves the water in the same direction as the wind, that is, currents from the equator and tropics move warm water northward toward higher latitudes, and currents from the poles move cooler water southward toward lower latitudes.

What is a current? Oceanic currents describe the movement of water from one location to another. Currents are generally measured in meters per second or in knots (1 knot = 1.85 kilometers per hour or 1.15 miles per hour). Oceanic currents are driven by three main factors: 1. The rise and fall of the tides. Tides create a current in the oceans, which are strongest near the shore, and in bays and estuaries along the coast.

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.

Currents Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect. Click the image for a larger view. Coastal currents are affected by local winds. Surface ocean currents, which occur on the open ocean, are driven by a complex global wind system.

(q). Surface and Subsurface Ocean Currents Surface Ocean Currents An ocean current can be defined as a horizontal movement of seawater at the ocean's surface. Ocean currents are driven by the circulation of wind above surface waters. Frictional stress at the interface between the ocean and the wind causes the water to move in the direction of the wind.Large ocean currents are a response of the atmosphere and ocean to the flow of energy from the tropics to polar regions.n either side of the equator, in all ocean basins, there are two west flowing currents: the North and South Equatorial (Figure 8q-1) . These currents flow between 3 and 6 kilometers per day and usually extend 100 to 200 meters in depth below the ocean surface.

Ocean Currents They can be either surface or deep water. Because ocean currents circulate water worldwide, they have a significant impact on the movement of energy and moisture between the oceans and the atmosphere. As a result, they are important to the world’s weather.eep water currents, also called thermohaline circulation, are found below 400 meters and make up about 90% of the ocean. Like surface currents, gravity plays a role in the creation of deep water currents but these are mainly caused by density differences in the water.

- The ocean's waters are constantly being moved about by powerful currents. Surface currents are largely wind-driven, although the rotation of the earth, the presence of continents, and the oceans' internal dynamics also have a strong influence.

Ocean Circulations 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.

Ocean Currents This heat is transported by ocean currents. In this way, the ocean currents help regulate Earth's climate by facilitating the transfer of heat from warm tropical areas to colder areas near the poles. The water of the ocean surface moves in a regular pattern called surface ocean currents. On this map, warm currents are shown in red and cold currents are shown in blue. Image Credit: Windows to the Universe. The global wind patterns cause the surface currents to form in the uppers layer of the ocean.

6th grade - ocean currents, atmosphere and energy transfer Deep currents. Movements of ocean water far below the surface. These are caused by differences in water density. When water cools, its molecules move closer together and make it denser. The cooler, denser water sinks. These currents carry colder denser water from polar regions to other parts of the earth. Density.

How Ocean Currents Work More Surface Currents. As you've probably gathered by now, wind and water are inseparable. To understand surface ocean currents, which, as their name suggests, occur in the open ocean, you should know a little about the winds that fuel them. Some of these wind patterns are caused by the Coriolis force.

- 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.

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.

- How do some deep ocean currents form? Deep ocean currents are caused by 3 things:    change in temperature  change in salinity by evaporation  change in salinity by freezing   Because colder water and s … altier water are more dense, they sink,  and the motion causes deep currents. 8 people found this useful.

What Causes Convection Currents? Convection currents are caused by an uneven temperature within something. Convection currents happen within the Earth's magma, water and air. It can happen in anything that is not solid and has parts that are cooler or warmer than other parts.
