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.

What is the cause of a surface current?

Surface currents are created by three things: global wind patterns the rotation of the Earth and the shape of the ocean basins. Surface currents are extremely important because they distribute heat around the planet and are a major factor influencing climate around the globe.

What is the pattern of ocean currents?

Ocean currents are movements of surface water. … The currents set up circular loops or gyres. Gyres are spiral oceanic surface currents and are found in both the Northern and Southern Hemispheres. The pattern of current flow is clockwise in the Northern Hemisphere and anti-clockwise in the Southern Hemisphere.

What causes breakers to form quizlet?

As you walk toward the water you see several waves like those in the image in the shallow water. These waves are called breakers. What causes breakers to form? … Warm water replaces cool surface water.

What is the primary factor in the flow of the 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.

What causes ocean currents quizlet?

A directional movement of ocean water surface currents result from steady winds over the ocean surface deep ocean currents result from density variations due to temperature and salinity differences.

Which factors cause the 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 two factors affect the currents of the ocean?

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 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.

What are the reasons responsible for the formation of deep ocean currents?

Deep ocean currents are driven by density and temperature gradients. … Because the movement of deep water inocean basins is caused by density-driven forces and gravity deep waters sink into deep ocean basins at high latitudes where the temperatures are cold enough to cause the density to increase.

Are ocean currents caused by waves?

Most waves in the ocean are wind generated waves. Ocean surface currents are produced by major overall patterns of atmospheric circulation the Coriolis Effect and the shape of each ocean basin. … Deep ocean circulation is density driven circulation produced by differences in salinity and temperature of water masses.

What are the patterns of surface ocean circulation?

The three main patterns of ocean circulation are gyres upwelling and thermohaline circulation.

What causes warm and cold water to move in patterns?

The sun evenly heats the ocean’s surface. This heat causes the water to move. The sun causes uneven heating. The changes in temperature makes the cold water sink and warm water rise which moves water.

What is the Coriolis effect caused by?

The Coriolis effect is a natural event in which objects seem to get deflected while traveling around and above Earth. The planet Earth is constantly rotating or spinning from west to east. Every 24 hours it completes a full rotation. This rotation causes the Coriolis effect.

What are the forces that cause the ocean to circulate quizlet?

The ocean has an interconnected current or circulation system powered by wind tides the Earth’s rotation (Coriolis effect) the sun (solar energy) and water density differences. The topography and shape of ocean basins and nearby landmasses also influence ocean currents.

Which factor drives surface ocean currents Brainly?

Answer: Explanation: 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 two things that cause ocean waves Brainly?

Answer: Waves transmit energy not water and are commonly caused by the wind as it blows across the ocean lakes and rivers. Waves caused by the gravitational pull of the moon and the sun are called tides. The ebb and flow of waves and tides are the life force of our world ocean.

Which primary mechanism causes 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.

What affects ocean and atmospheric flow patterns?

Weather and Climate. Weather and climate are influenced by interactions involving sunlight the ocean the atmosphere ice landforms and living things. These interactions vary with latitude altitude and local and regional geography all of which can affect oceanic and atmospheric flow patterns.

Which of the following factors affects the flow of ocean currents?

There are four factors affecting the origin and flow of Ocean Currents i.e. Rotation and gravitational force of the Earth Oceanic factors (temperature salinity density pressure gradient and melting of ice) atmospheric factors (atmospheric pressure winds rainfall evaporation and insolation) factors that …

What causes ocean currents quizlet earth science?

The oceans contain streamlike movements of water. Ocean currents that occur at or near the surface of the ocean caused by wind.

How do the causes of surface and deepwater currents differ?

How do the causes of surface and deepwater currents differ? Surface currents are caused by wind deepwater currents are caused by differences in water density. Wind and ocean currents do not move in straight lines instead they curve as they move across the planet.

Which factor drives 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 influences the path that surface currents take?

The water starts flowing in the same direction as the wind. But currents do not simply track the wind. Other things including the shape of the coastline and the seafloor and most importantly the rotation of the Earth influence the path of surface currents.

List the three factors that control surface currents: Global winds continental deflection and temperature and the Coriolis effect.

What are the reasons responsible for the formation of deep ocean currents Class 8?

The difference in temperatures of various parts of the ocean is the major reason behind the deep-sea currents. Warm water has lower salinity and density. Such water comes to the surface of the sea. Cold water with high density goes down.

Which of the following is responsible for deep ocean circulation?

The answer is Option A. The differences in water temperature and salinity are responsible for deep water or ocean currents. Other inducing factors for water currents are wind cabbeling Coriolis effect and breaking waves.

What is the sequence that produces movement of ocean water?

Seawater motions are the result of waves tides and currents (Figure below). Ocean movements are the consequence of many separate factors: wind tides Coriolis effect water density differences and the shape of the ocean basins.

What causes ocean swells?

As wind blows across the water’s surface friction occurs and energy is transferred from wind to water. The result is a rising crest that forms into a wave. Over time and distance sustained wind strength and duration build up a large amount of energy beneath the ocean’s surface forming deeper waves known as swells.

What causes ocean waves and currents?

What causes ocean waves? Ocean waves are caused by wind moving across the surface of the water. The friction between the air molecules and the water molecules causes energy to be transferred from the wind to the water. This causes waves to form.

What are surface current patterns?

Surface ocean currents form large circular patterns called gyres. Gyres flow clockwise in Northern Hemisphere oceans and counterclockwise in Southern Hemisphere oceans because of the Coriolis Effect. creating surface ocean currents. Near the Earth’s poles gyres tend to flow in the opposite direction.
