How are currents formed?
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 causes 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.
How do surface currents form and flow?
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.
How are surface ocean currents made?
How are Ocean Currents Formed? 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.
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.
Which factors cause the ocean currents?
The movement of ocean waters or ocean currents takes place due to the effect of earth's rotation, wind difference, salinity and density of seawater, etc. The current in the ocean is originated due to the combined effect of all these factors acting internally as well as externally.
Which factor causes surface ocean currents quizlet?
Wind direction, the spin of Earth, and differences in temperature contribute to currents. Currents occur at the surface of and deep within the ocean. The Coriolis effect contributes to the direction of current flow. Wind direction, the spin of Earth, and differences in temperature contribute to currents.
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 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.
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 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 factors affect 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 surface currents quizlet?
surface currents. ocean currents that occur at or near the surface of the ocean, caused by wind.
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.
Why ocean currents are formed?
What makes ocean currents flow? Tides contribute to coastal currents that travel short distances. 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 water starts flowing in the same direction as the wind.
What is a surface wave made of?
Surface waves are caused when P waves and S waves come to the surface. Examples are the waves at the surface of water and air (ocean surface waves). Another example is internal waves, which can be transmitted along the interface of two water masses of different densities.

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.
Which best describes how ocean currents are created?
The main reason by which the ocean currents are formed is the rotation of earth. The earth rotates on its own axis and due to this reason there is a huge mixing of the water from the equator and poles which is termed as ocean currents.
How is surface waves formed?
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.
How are surface waves generated?
Surface waves are typically generated when the source of the earthquake is close to the Earth's surface. As their name suggests, surface waves travel just below the surface of the ground.

What consists of a surface wave?
Surface waves are caused when P waves and S waves come to the surface. Examples are the waves at the surface of water and air (ocean surface waves). Another example is internal waves, which can be transmitted along the interface of two water masses of different densities.
Where do surface waves start?
Surface waves are similar in nature to water waves and travel just under the Earth's surface. They are typically generated when the source of the earthquake is close to the Earth's surface.
Are surface waves produced by P and S waves?
After both P and S waves have moved through the body of Earth, they are followed by surface waves, which travel along Earth's surface. Surface waves travel only through solid media. They are slower-moving than body waves but are much larger and therefore more destructive.
How are surface waves formed?

What type of waves are surface waves?
Surface waves travel only through solid media. They are slower-moving than body waves but are much larger and therefore more destructive. The two types of surface waves are named Love waves and Rayleigh waves, after the scientists who identified them.
What are LP and S waves?
Primary (P) and secondary (S) waves are two types of waves caused by earthquakes. They are defined based on when they arrive and are felt on the surface. P waves, or primary waves, arrive first while S waves, or secondary waves, arrive second. Both waves cause the ground to shake when an earthquake occurs.
What are the surface waves called?
The two types of surface waves are named Love waves and Rayleigh waves, after the scientists who identified them. Love waves have a horizontal motion that moves the surface from side to side perpendicular to the direction the wave is traveling.
What is Rayleigh and Love waves?
Love and Rayleigh waves Some earthquake waves move only along the surface of the earth. Love waves shake the surface side-to-side. Rayleigh waves move the surface of the earth around in a circle, forward and down then back and up. This is the same as the motion in an ocean wave.
