What are surface currents driven by quizlet?
What causes the two major types of ocean currents? surface currents are caused by wind while thermohaline currents are caused by density differences caused by salinity and temperatures.
Are surface currents wind driven?
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.
What is surface ocean circulation driven by?
The circulation of the surface ocean is driven primarily by surface winds. As we have seen, winds blow from areas of high atmospheric pressure to regions of low atmospheric pressure.
Are surface currents density driven?
Deep ocean currents are density-driven and differ from surface currents in scale, speed, and energy. Water density is affected by the temperature, salinity (saltiness), and depth of the water. The colder and saltier the ocean water, the denser it is.
What three controls surface currents quizlet?
List the three factors that control surface currents: Global winds, continental deflection and temperature, and the Coriolis effect.
What causes ocean surface currents quizlet?
What causes surface currents to move? It is caused by wind action, Earth's spin, and the shape of the continents. Also, the speed, direction, and volume of water can be affected by the uneven heating of the atmosphere. The force of wind blowing over the top of the Earth.
What are winds driven by?
These winds are subject to the Coriolis Effect, which creates their motion based on the rotation of the earth. Wind will rotate in a clockwise direction in the northern hemisphere and a counter clockwise direction in the southern hemisphere. Because of the Coriolis Effect, water will also rotate in this direction.
What is a wind driven current called?
A Wind generated current is a flow in a body of water that is generated by wind friction on its surface. Wind can generate surface currents on water bodies of any size.
What primarily drives the surface ocean currents quizlet?
What primarily drives the surface ocean currents? Coriolis forces.
What is surface ocean currents?
Surface currents are driven by global wind systems that are fueled by energy from the sun. These currents bring heat from the tropics to the polar regions; the Gulf Stream, for instance, brings warm water along the eastern coast of the US up to Northern Europe.
What is density-driven?
A wide variety of companies operate density-driven business models. Their business is predicated on physically visiting one customer after another to deliver a product or service, typically via vans driving a route from a warehouse or depot.
What three things cause 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.
What are three factors that drive ocean currents?
Oceanic currents are driven by three main factors:
- 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. …
- Wind. Winds drive currents that are at or near the ocean's surface. …
- Thermohaline circulation.

What causes ocean currents?
Ocean currents are driven by wind, water density differences, and tides. 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).
What is a surface current?
(′sər·fəs ‚kə·rənt) (oceanography) Water movement which extends to depths of 3-10 feet (1-3 meters) below the surface in nearshore areas, and to about 33 feet (10 meters) in deep-ocean areas. Any current whose maximum velocity core is at or near the surface.
What are the two main driving forces of ocean currents?
Oceanic currents are driven by three main factors:
- 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. …
- Wind. Winds drive currents that are at or near the ocean's surface. …
- Thermohaline circulation.

What is the driving force of deep ocean currents?
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 are wind driven currents called?
These ciruclating patterns are called gyres. They move in the same directions as the winds in their respective hemispheres: clockwise in the northern hemisphere, and counter- clockwise in the southern hemisphere.
How do surface currents move?
Surface currents are powered by the sun and driven by the wind. The sun drives the global wind systems on Earth. When this wind blows over the surface of the ocean, it causes waves to form and the water at the surface to move. The force of the wind pushing on the water results in what are known as surface currents.
What is the most common source of energy for surface currents?
Surface currents 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.
What factors control ocean currents?
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.
What causes surface waves?
Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. These types of waves are found globally across the open ocean and along the coast.
What is the primary driving force of surface ocean currents quizlet?
Wind is the primary driving force of surface currents. The Coriolis effect deflects the currents to the right (Northern Hemisphere) or left (Southern Hemisphere) of their path of motion (the prevailing wind direction).
What three factors control the path of a surface current?
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.
What primary driving force causes surface ocean water to move?
Wind is the primary force driving surface currents in the ocean. The sun heats the surface of the earth unevenly because of the shape and tilt of the earth. Warm air masses form where the sun's radiation is most intense, which is at the equator.
How is wind circulation driven?
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. These winds are subject to the Coriolis Effect, which creates their motion based on the rotation of the earth.
What causes water currents to move?
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. The currents then bend to the right, heading north.
What is the energy source for ocean surface waves?
Wind blows across the ocean, creating waves The sun heats up air at different places around the globe, which creates wind that blows over ocean surfaces. The wind creates surface waves, like those that crash on a beach.
What are 4 factors that drive ocean currents?
Four Factors That Create Ocean Currents
- Wind. Wind is the single biggest factor in the creation of surface currents. …
- Water Density. Another major factor in the creation of currents is water density, caused by the amount of salt in a body of water, and its temperature. …
- Ocean Bottom Topography. …
- Coriolis Effect.

What are three factors that affect surface ocean currents?
Explanation
- Continental deflections: The continents that rise above sea level cause the surface currents to change direction.
- Coriolis effect: This is the deflection of wind and ocean currents due to the Earth's rotation.
- Global winds: These are the wind patterns that circulate the warm and cold air around the globe.
