What is the primary energy source that drives 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.
How does wind cause surface currents quizlet?
How do global winds work? Winds that blow across the Earth's surface pushes the water causing surface currents to form.
What is the term for the turbulent water created by breaking waves *?
The turbulent water created by breaking waves is called surf. true. A baymouth bar is a manmade feature designed to control wave erosion.

How do prevailing winds produce ocean currents?
In the Northern Hemisphere, for example, predictable winds called trade winds blow from east to west just above the equator. 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.
What causes surface ocean 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.
How are surface ocean currents produced?
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 causes ocean 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 ocean currents form?
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 is wave refraction?
NARRATOR: Refraction is the change in direction of a wave as it passes from one medium to another. Refraction is caused by the wave's change of speed.

Which of the following is correct regarding a wave in the open ocean group of answer choices?
Which of the following is correct regarding a wave in the open ocean? Water particles move vertically in circular orbital motion.
What do the prevailing winds do?
Prevailing winds are important for determining locations of wind farms in order to generate electricity. Prevailing winds also determine the amount of rainfall that different regions get. In Southeastern Asia, these winds result in the formation of monsoons and deserts.
How are ocean surface currents formed?
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 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.
What causes 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.
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.
What is reflection refraction and diffraction?
Reflection involves a change in direction of waves when they bounce off a barrier; refraction of waves involves a change in the direction of waves as they pass from one medium to another; and diffraction involves a change in direction of waves as they pass through an opening or around a barrier in their path.
How does diffraction of light occur?
More specifically when applied to light, diffraction of light occurs when a light wave passes by a corner or through an opening or slit that is physically the approximate size of, or even smaller than that light's wavelength.
What are ocean landforms created by?
Coastal landforms are the landforms along the coastline that are mostly formed by erosion and sediments from waves, longshore currents, rip currents, tides, and climatic factors like wind and rainfall, and temperature include headlands, cliffs, bays, spits, salt marshes, and beaches.
How are ocean and sea landforms created?
Erosion by water and wind can wear down land and create landforms like valleys and canyons. Both processes happen over a long period of time, sometimes millions of years.
Where does the prevailing wind come from?
Winds occur where high-pressure air masses seek low-pressure areas. Prevailing winds are largely predictable and named for broad areas of the Earth over which they form. Convection cells circulate air flow and help regulate temperature around the globe.
What are prevailing winds?
Prevailing winds are winds that blow from a single direction over a specific area of the Earth. Areas where prevailing winds meet are called convergence zones. Generally, prevailing winds blow east-west rather than north-south. This happens because Earth's rotation generates what is known as the Coriolis effect.
What do we mean by prevailing wind?
Definition of prevailing wind : the usual wind in an area or region —used to refer to the direction of the wind The prevailing wind in this region is from the east.
How are dispersion scattering interference and diffraction different from one another?
Light scattering is the ability of particles to absorb light and scatter it in all directions. Diffraction is the bending of light when it encounters an obstacle or an opening. Interference is the result of the superposing of waves from different sources.
What is diffraction and dispersion?
Diffraction is where light spreads out after passing through a gap or going around an obstacle, and can lead to interference patterns. And dispersion is the process by which light of different frequencies, or colors, refracts by different amounts.
What is diffraction and refraction?
Refraction is the change in direction of waves that occurs when waves travel from one medium to another. Refraction is always accompanied by a wavelength and speed change. Diffraction is the bending of waves around obstacles and openings.
What is diffraction wave?
Wave diffraction is the process by which wave energy spreads perpendicularly to the dominant direction of wave propagation. Wave diffraction is specifically concerned with sudden changes in boundary conditions such as at breakwater roundheads, where wave energy is transferred into the shadow zone by diffraction.
What landforms are created by wind?
Dunes are mounds of loose sand created by wind and are the most well known aeolian features.
How do currents and waves produce landforms?
The role of tides in molding coastal landforms is twofold: (1) tidal currents transport large quantities of sediment and may erode bedrock, and (2) the rise and fall of the tide distributes wave energy across a shore zone by changing the depth of water and the position of the shoreline.
