How does an ocean wave become a breaker at the shoreline? Report Abuse. As the wave approaches the shoreline the bottom part of the wave comes in contact with the bottom (ground) which causes friction and slows the water at the bottom of the wave causing the top of the wave to break as there is no longer the volume of water under it.Lee. Easygo · 6 years ago.Thumbs up.est Answer: The bottom of the wave slows down because it is hitting into the slope of the beach. The top of the wave continues on at the same speed and this causes it to roll over the bottom, hence the break. Source(s): Lozza_07 · 6 years ago.

Coastal Change Hazards: Hurricanes and Extreme Storms Beach Erosion. Beach erosion occurs when waves and currents remove sand from the beach system. The loss of sand causes the beach to become narrower and lower in elevation (Figure 1).Storm waves carry the sand offshore, depositing and storing the sediment in large sandbars.each erosion occurs when waves and currents remove sand from the beach system. The loss of sand causes the beach to become narrower and lower in elevation (Figure 1).

Oceanography Ch. 10 The deposit on the shore area. Consists of wave worked sediment that moves along the wave cut bench, (a flat, wave-eroded surface) It may continue from the coastline across the nearshore region to the line of breakers. The beach is the entire active area of a coast that experiences changes due to breaking waves.

- Diagram from above of a rip current: breakers are crossing a sand bar off the shore. the pushed-up water can most easily travel back out to sea through a gap in the sand bar. This creates a fast rip current.

Coasts of Erosion Coasts of Erosion. Coasts of erosion form as a result of high energy waves, large fetch, high exposure and limited deposition. They are also associated with drift alligned coasts that are influenced by longshore drift. This transfer of sediment along the coast limits the development of beaches and leads to greater cliff exposure, hence cliff retreat.

- Section 1. Shoreline Erosion and Deposition. Key Concept Beaches and shorelines are shaped largely by the action of ocean. waves. What You Will Learn. • Energy from waves crashing against rocks affects shorelines. • Shoreline features are created by wave erosion. • Waves deposit sediment at the shore to form beaches. Why It Matters. Waves erode and deposit materials along beaches and shorelines throughout. California and the world. Two ingredients are needed to make sand: rock and energy. Rock is usually. available on the shore.

Wave-cut platform The formation of a wave cut platform. Wave-cut platforms form when destructive waves hit against the cliff face, causing undercutting between the high and low water marks, mainly as a result of corrosion and hydraulic power, creating a wave-cut notch.

- Some shorelines are characterized by permanent rip currents which may be found in a fixed location such as a break in a reef or other hard structure. Some rip currents are persistent, lasting for many days or months in one location. Rip currents may also migrate along a stretch of coastline.

- Abrasion in coastal erosion. Coastal abrasion occurs as breaking waves which contain sand and larger fragments erode the shoreline or headland. This removes material resulting in undercutting and possible collapse of unsupported overhanging cliffs. Abrasion platform

Correct answer none response feedback question 9 5 Correct Answer: [None] Response Feedback:  Question 10 4 out of 10 points When you are at the beach, you notice that the waves seem to break at the same point as they come towards shore. Explain what is happening beneath the surface to cause the waves to break at this point. Selected Answer: Breakers form when orbital particle motion at the trough of the wave slows more rapidly than at the crest. The water at the crest of the wave will move forward and outrun the base of the wave.

Island Beach State Park Shoreline sand movement. The wind and the sea are constantly moving the sand you see on the beach. Sand is deposited on the beach by waves with a weak backwash. The material brought onto the beach either comes from the sandy bottom under the water or from other areas of the beach. A strong backwash has the opposite effect. A destructive wave pulls sand from the beach into the water.

- Soo-nam-ee (harbor wave). A tsunami has been called a tidal wave but has nothing to do with the tide. Rather, it is an unusual increase (sometimes preceded by a decrease before the first wave arrives) in sea level that floods low-lying areas and causes unusual currents in harbors and bays. tsunami is not a single wave but a series of long period waves that can cause havoc along the coastline, in harbors and bays, and move up coastal rivers. The unusual, wild oscillations of sea level caused by the tsunami can last for hours following arrival of the first wave.

- At this point the energy of the forward motion of the wave is expended in a brief moment when the breaking wave rushes up the beach (surf zone), as so called swash. When the energy is expended by moving up on the beach (friction, sediment transport), the water returns seaward as backwash (see above).

Longshore Currents, Shoreline, and Beach Drafts A shoreline is not static. As waves appoach shore and “feel the bottom”, water piles up and breakers form (see “Waves”). Primarily these waves, breaking at an angle to the shoreline, are what generate a “longshore current” that parallels the shore. Importantly, the longshore current not only moves water in the surf zon.

Ocean surface wave There is surprisingly little actual forward motion of individual water particles in a wave, despite the large amount of forward energy it may carry. The great majority of waves one sees on an ocean beach result from distant winds. Three factors influence the formation of wind waves: Windspeed; length of time the wind has blown over a given area; and distance of open water that the wind has blown over (called fetch).

Rip Currents: The Ocean's Deadliest Trick There are many different types of rip currents, and they form in several ways. Quickly changing wave heights, which occur when a large set of swells rolls in, can trigger a rip current. Rip currents can also occur at spots where there's a break in a sandbar; there, water is funneled out to sea. These channels in sandbars lie just off the beach. When water returns to the ocean, it follows the path of least resistance, which is typically through these channels.

- Killer Waves. Photograph by Deshakalyan Chowdhury/AFP/Getty Images. A tsunami is a series of ocean waves that sends surges of water, sometimes reaching heights of over 100 feet (30.5 meters), onto land. These walls of water can cause widespread destruction when they crash ashore.iller Waves. Photograph by Deshakalyan Chowdhury/AFP/Getty Images.

- The type of wave energy that Oceanlinx converts into electricity is a combination of the kinetic and potential energy of water particles. Waves cause the water particles to oscillate in elliptical paths, with the maximum kinetic energy happening as the height of the wave passes through the mean sea level.You can feel the constantly varying effect when floating in the surf zone, as it pulls you back and forward, and up and down.t is the ocean swell waves that are the best form of wave for Oceanlinx technology. Wave energy is not to be mistaken for tidal energy. Tides are caused by the gravitational pull of the moon and sun, and have a period of around 12 hours, whereas ocean waves have a period of around 10 seconds.

Rip current A rip current forms because breaking waves push water towards the land. Water that has been pushed up near the beach flows together (as feeder currents), and this water finds a place where it can flow back out to sea.he pull of the current also fades out completely at the head of the rip, outside the zone of the breaking waves, so there is a definite limit to how far the swimmer will be taken out to sea by the flow of a rip current.
