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.
What directly causes surface ocean currents?
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 causes surface currents for kids?
Surface currents are caused mainly by wind blowing across the surface of the water and the friction causing waves. Deep water currents are caused by many things, such as temperature changes, salinity, gravity, and density. Deep water currents are also one factor in weather climates.
What are the causes of currents?
Ocean currents are driven by wind, water density differences, and tides….Oceanic currents are driven by three main factors:
- The rise and fall of the tides. …
- Wind. …
- Thermohaline circulation.

What are surface 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 Surface current?
surface current. A current which does not extend more than 8 or 10 feet below the surface. Also, fresh water running over salt at the mouths of great rivers.
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.
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 the 3 main causes of ocean currents?
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.
What causes surface currents and deep currents?
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.
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 are 4 factors that cause 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 an example of a surface current?
Two examples are the California Current (Cal) in the Pacific ocean basin and the Canary Current (Can) in the Atlantic ocean basin. The North Equatorial Current (NE) and the South Equatorial Current (SE) flow in the same direction. The SE turns south and behaves the opposite of the gyres in the Northern Hemisphere.

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.

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.
