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.
What three drives 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.
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 are surface currents and deep currents driven by?
Deep currents are driven by temperature and water density/salinity. Of course, deep currents impact surface currents, which carry warm water to the poles. Surface currents are also driven by global wind systems fueled by energy from the sun. Factors like wind direction and the Coriolis effect play a role.
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?
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.
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 are surface currents?
A current is a stream of moving water that flows through the ocean. Surface currents are caused mainly by winds but not daily winds. Surface currents are caused by the major wind belts. These winds blow in the same direction all the time. So they can keep water moving in the same direction.
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 are two major drivers of surface ocean current and deep ocean current?
There are two main types of ocean currents: currents driven mainly by wind and currents mainly driven by density differences.
What is the primary driving force for surface ocean currents?
The major driving force of surface currents is the wind. The winds that drive the Gulf Stream are the Westerlies. They blow in an eastwards direction and penetrate to a depth of approximately 200 metres, dragging the surface water at high velocity over a long distance.
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 winds drive ocean currents?
Prevailing winds are examples of prolonged winds that produce large-scale ocean basin currents. The simplified map in Fig. 3.13 shows the surface winds that flow from regions of high atmospheric pressure over the world's oceans. These are winds that drive the system of surface currents in the ocean.
How are currents caused?
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.
Whats 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 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 are surface currents mainly caused by?
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.
What energy sources drive the ocean surface?
There are two major sources of energy for driving ocean currents: the sun (via wind) and density (via salt content and temperature).
What primarily drives the surface ocean currents quizlet?
What primarily drives the surface ocean currents? Coriolis forces.
What is the main driver for the direction that surface ocean currents flow?
Wind 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.
What are 4 factors that drive ocean currents?

What is the primary force that drives ocean waves?
What is the primary force that drives ocean waves? Waves are most commonly caused by wind. 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.
What are the forces 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 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.

There are two major sources of energy for driving ocean currents: the sun (via wind) and density (via salt content and temperature).
What is the main driver of near surface ocean 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 is the dominant driving force that creates surface ocean currents?
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.
