Coriolis effect
The Coriolis force acts in a direction perpendicular to the rotation axis and to the velocity of the body in the rotating frame and is proportional to the object’s speed in the rotating frame (more precisely to the component of its velocity that is perpendicular to the axis of rotation).

What are 3 causes of 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.

What causes surface currents and deep ocean currents?

What causes surface 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.

What are the 5 causes of oceanic current?

Causes of Ocean Currents
  • Solar heating. it causes water to expand. …
  • Wind. The Wind is responsible for ocean currents as it blows the water on the surface causing the currents. …
  • Gravity. Gravity tends to pull items towards the surface of the earth. …

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.

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.

How are surface currents created?

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 causes convection currents to form in the ocean?

The sun causes uneven heating which leads to differences in air pressure. This causes wind which moves the water at the surface of the ocean. … Uneven heating causes density differences in the water which causes convection currents.

What causes wave?

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. … The gravitational pull of the sun and moon on the earth also causes waves.

What are the four factors 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 are the primary causes of two types of ocean currents?

There are two main types of ocean currents: currents driven mainly by wind and currents mainly driven by density differences. Density depends on temperature and salinity of the water.

What causes the movement of water?

There is a lot of water movement in the ocean. … There currents are set in motion by variations in water density caused by differences in temperature and salinity a process called convection.

What causes a surface current 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 is the primary cause of surface currents in the ocean quizlet?

1. 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). The location of the continents also affects the pattern of surface currents.

Why are surface currents at the surface of the ocean quizlet?

Surface currents occur at the surface of the ocean and are caused by global winds the Gulf Stream is an example. Deep currents occur deep in the ocean and are influenced by water density salinity and temperature.

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. … So they can keep water moving in the same direction.

What are surface currents in the ocean?

The water of the ocean surface moves in a regular pattern called surface ocean currents. … The water at the ocean surface is moved primarily by winds that blow in certain patterns because of the Earth’s spin and the Coriolis Effect. Winds are able to move the top 400 meters of the ocean creating surface ocean currents.

How are surface currents connected to deep ocean currents?

As the seawater gets saltier its density increases and it starts to sink. Surface water is pulled in to replace the sinking water which in turn eventually becomes cold and salty enough to sink. This initiates the deep-ocean currents driving the global conveyer belt.

How are the surface and deep ocean currents different?

Surface ocean currents can occur on local and global scales and are typically wind-driven resulting in both horizontal and vertical water movement. … Deep ocean currents are density-driven and differ from surface currents in scale speed and energy.

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 are the three main sources of convection?

I Heat Production and Heat Transfer in the Mantle

The primary sources of thermal energy for mantle convection are three: (1) internal heating due to the decay of the radioactive isotopes of uranium thorium and potassium (2) the long-term secular cooling of the earth and (3) heat from the core.

What are three factors that influence 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 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 are the 3 causes of waves?

Waves are dependent on three major factors – wind speed wind time and wind distance.

Why does brushing your hair give you waves?

Brush the back of your head straight down. The heat from the blow dryer and the tension from the hard side of the wave brush cause the spiral hair to flatten out into an S shape. The continuous reoccurring S shape is what gives the hair the wave pattern.

What is one factor in the creation of surface ocean currents?

Wind is the single biggest factor in the creation of surface currents. Strong winds moving across an expanse of water move the surface of the water.

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.

How many major surface currents are found in the Earth’s oceans?

There are five major ocean-wide gyres—the North Atlantic South Atlantic North Pacific South Pacific and Indian Ocean gyres. Each is flanked by a strong and narrow “western boundary current ” and a weak and broad “eastern boundary current” (Ross 1995).

What is the movement of water in the oceans called?

The horizontal motion refers to the ocean currents and waves. The vertical motion refers to tides. Ocean currents are the continuous flow of huge amount of water in a definite direction while the waves are the horizontal motion of water.

What causes the movement of water through a plant?

Osmosis plays a central role in the movement of water between cells and various compartments within plants. In the absence of transpiration osmotic forces dominate the movement of water into roots. … Root pressure results when solutes accumulate to a greater concentration in root xylem than other root tissues.
