What Function Do The Wind-driven Currents Play In The Transport?
Cooler water is more dense so it begins to sink. 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 its role in wind driven circulation?
Wind driven circulation describes the process in which winds moving along the surface of the ocean push the water in their direction and create currents near the surface. … Because of the Coriolis Effect water will also rotate in this direction.
How do wind driven currents affect the ocean?
Major surface ocean currents in the open ocean however are set in motion by the wind which drags on the surface of the water as it blows. … The winds pull surface water with them creating currents. As these currents flow westward the Coriolis effect—a force that results from the rotation of the Earth—deflects them.
How is wind driven circulation linked to deep ocean circulation?
Thermohaline circulation begins in the Earth’s polar regions. When ocean water in these areas gets very cold sea ice forms. The surrounding seawater gets saltier increases in density and sinks. Winds drive ocean currents in the upper 100 meters of the ocean’s surface.
What are the ocean currents that carry warm water?
The Gulf Stream is one of the strong ocean currents that carries warm water from the tropics to the higher latitudes.
What are wind-driven currents called quizlet?
Surface currents are wind-driven movements of water at or near the ocean’s surface and thermohaline currents are the slow deep density-driven currents that affect the vast bulk of seawater beneath the pycnocline.
What are surface currents?
What is the name of the transport process that is primary wind-driven?
What is the wind-driven use of ocean water?
Is ocean circulation driven by wind?
Large-scale surface ocean currents are driven by global wind systems that are fueled by energy from the sun. These currents transfer heat from the tropics to the Polar Regions influencing local and global climate.
How do winds cause surface currents?
Wind is the most important cause of surface currents. When strong sustained winds blow across the sea friction drags a thin layer of water into motion. The movement of the very topmost layer of the sea pulls on the water just beneath which then in turn starts the layer under it moving.
What is responsible for surface currents?
Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction Coriolis forces from the Earth’s rotation and the position of landforms that interact with the currents.
Why are surface currents important?
What function do the wind driven currents play in the transport of heat energy in the oceans?
Effect on Global Climate
Surface currents play a large role in determining climate. These currents bring warm water from the equator to cooler parts of the ocean they transfer heat energy.
How do currents work?
The ocean currents helps in the navigation because a current has it’s own momentum which helps the ships to move along with the current that passes through this current direction.
How does wind blowing over a surface current influence the climate downwind?
how does wind blowing over surface currents influence the climate down wind? … the friction of wind blowing from the north causes the water next to the west coast of the continent to move. Coriolis effect deflects the water to the right (in the Northern Hemisphere) and the resultant Ekman transport moves it offshore.
What are the three important properties of air that illustrate how air circulation affects climate?
- Cold air sinks because it is denser than warm air. As the air sinks it compresses and warms.
- Warm air rises. It expands and cools as it rises.
- Warm air can hold more water vapor than cold air can.
What forces are responsible for the movement of ocean water in currents quizlet?
What causes Surface ocean currents and how do they flow/what direction do they flow? Surface currents develop from friction between the ocean and the wind that blows across its surface.
How do wind currents work?
One of the driving forces of the global atmospheric air current is the uneven heating of the Earth’s surface. … Hot air rises and cold air sinks so air currents form when the atmosphere moves excess hot air from the warmer low latitudes to cooler high latitudes and cool air rushes in to replace it.
What is Surface winds?
surface wind The wind close to the Earth’s surface the velocity of which is usually measured at a standard height of 10 m. Surface-wind velocity is reduced by the frictional effect of the underlying surface. The actual wind is a balance of pressure-gradient force Coriolis effect and frictional effects.
What causes wind?
Wind is the movement of air caused by the uneven heating of the Earth by the sun. … Warm equatorial air rises higher into the atmosphere and migrates toward the poles. This is a low-pressure system. At the same time cooler denser air moves over Earth’s surface toward the Equator to replace the heated air.
What is wind drive?
The best defensive driving technique you can use for wind is driving at slower speeds. Wind generally reduces your steering control. Tail winds push the car increasing speed. … Wind gusts occur suddenly and can cause total loss of vehicle control requiring an adjustment in speed and steering.
What is the difference between ocean current wind driven circulation and thermohaline circulation?
Why do currents tend to flow around the periphery of an ocean basin?
Why do currents tend to flow around the periphery of an ocean basin? Due to balance between Ekman transport trying to push the water to the center of the basin and the high point in the center holding the flow away.
What are the important forces of ocean currents explain them?
Ocean currents are driven by wind water density differences and tides. Oceanic currents describe the movement of water from one location to another.
What role is played by the Coriolis effect in western boundary currents?
The Coriolis effect producing deflection influences the water currents in the western boundary. The generation of this effect depends on the rotational phenomenon of the Earth. As currents flow westward the Coriolis force affects the currents thus deflecting it towards the right.
What are density driven currents?
Ocean currents are formed when water layers move. Gravitational currents are formed when water masses of different densities sink or rise due to the interactions of gravitational and buoyant forces.
What forces are responsible for the movement of ocean water in currents What forces and factors influence the direction and nature of ocean currents?
These currents are on the ocean’s surface and in its depths flowing both locally and globally. Winds water density and tides all drive ocean currents. Coastal and sea floor features influence their location direction and speed. Earth’s rotation results in the Coriolis effect which also influences ocean currents.
Why is ocean circulation important?

What is the main driving force of surface currents?
The major driving force of surface currents is the wind. The winds that drive the Gulf Stream are the Westerlies.
