What are two forces through which ocean waves cause erosion?
Abrasion and impact are two forces that lead to erosion by waves.
How do waves cause erosion?
Explanation: As waves reach shallow water near the ocean shore, they begin to break. As the breaking waves hit the shoreline, their force knocks fragments off existing rock formations. Another way waves causes erosion is by forcing water into cracks in the rocks at the shoreline.
What are the 4 main ways waves cause erosion?
Destructive waves erode through four main processes; Hydraulic Action, Compression, Abrasion and Attrition. Image credit: Jeff Hansen, U.S. Geological Survey. Hydraulic Action is the sheer force of water crashing against the coastline causing material to be dislodged and carried away by the sea.
How do ocean waves cause erosion quizlet?
The force of waves striking the shoreline breaks rocks apart into small pieces. Those rocks cause abrasion and wear down the rocks into sand and the sand is carried away by the ocean. 2.
What forces can cause waves to form?
Waves form as a result of the water's motion, gravitational forces, and winds. The most common waves we see are created by wind. However other waves include those created by gravitational forces (e.g. tidal waves) and those created by underwater disturbances, such as earthquakes (e.g. tsunamis).
What is the force of waves?
For sound waves, the medium is air and the restoring force is air pressure. For water waves, the medium is the water and the restoring force is either surface tension or gravity. A wave, or a disturbance of a medium does not stay localized.
What are the two types of ocean waves?
Three types of water waves may be distinguished: wind waves and swell, wind surges, and sea waves of seismic origin (tsunamis).
What are some examples of wave erosion?
Landforms From Wave Erosion
- Wave-cut cliffs form when waves erode a rocky shoreline. They create a vertical wall of exposed rock layers.
- Sea arches form when waves erode both sides of a cliff. They create a hole in the cliff.
- Sea stacks form when waves erode the top of a sea arch. This leaves behind pillars of rock.

What type of force is erosion?
Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.
What causes water erosion?
What causes water erosion? Erosion is caused by the impact of raindrops on bare soil and by the power of running water on the soil surface. Natural erosion rates depend on inherent soil properties, slope, and climate, which together determine the ability of the site to support vegetation.
What are two features formed by wave deposition?
Some features form by wave-deposited sand. These features include barrier islands and spits. A spit is sand connected to land and extending into the water. A spit may hook to form a tombolo.
What causes ocean waves quizlet?
Ocean waves get their energy from wind blowing across the surface of the water. When the wind contacts the water, some of its energy is transferred.
What are the 3 types of ocean waves?
Three types of water waves may be distinguished: wind waves and swell, wind surges, and sea waves of seismic origin (tsunamis).
How much force do ocean waves have?
According to physicists, a breaking wave can apply a pressure of between 250-6,000 pounds per square foot (1,220-29,294 kilograms per square meter), depending on its height.
What is wave erosion?
Waves erode sediments from cliffs and shorelines. The sediment in ocean water acts like sandpaper. Over time, they erode the shore. The bigger the waves are and the more sediment they carry, the more erosion they cause (Figure below).
What are ocean waves caused by?
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.
What are two ways waves erode land?
Waves erode land through simple processes like Corrosion, Hydraulic Action, Solution and Attrition.
How does water cause erosion?
Water erosion occurs when rain or snowmelt displaces the soil on the ground. The more water flowing over the land, the more soil particles are moved or transported away. Land that has no vegetation—including farm fields that are left barren after crop harvest—are especially vulnerable to water erosion.
What are 2 types of erosion?
The main forms of erosion are: surface erosion. fluvial erosion.
What are the two types of erosion?
Sheet erosion describes erosion caused by runoff. Rill erosion describes erosion that takes place as runoff develops into discrete streams (rills). Finally, gully erosion is the stage in which soil particles are transported through large channels.
What are the erosional work of sea waves?
Work of Sea Waves The erosion and deposition of the sea waves gives rise to coastal landforms. Seawaves continuously strike at the rocks. Cracks develop. Over time they become larger and wider.
Which of the following are produced by wave erosion?
An arch is produced when waves erode through a cliff. When a sea arch collapses, the isolated towers of rocks that remain are known as sea stacks.
What force generates surface ocean waves quizlet?
Wind blowing across the surface of the ocean is the major mechanism that generates most ocean surface waves.
What causes waves quizlet?
~A wave is caused by a disturbance in a solid, liquid, or gas as energy is transmitted through a medium.
What are two types of ocean waves?
Three types of water waves may be distinguished: wind waves and swell, wind surges, and sea waves of seismic origin (tsunamis).
What causes erosion?
Erosion by Water Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment. Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.
What are the 3 causes of waves?
Waves are dependent on three major factors – wind speed, wind time and wind distance.
What force causes tides?
Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996).
What are two ways in which waves erode the land quizlet?
what are two ways in which waves erode the land? impact and abrasion.
Does wave refraction cause erosion?
The effects of wave refraction also tend to concentrate wave energy on headlands or protrusions that stick out of the coastline and tend to defocus or diverge the energy in embayments. This is important for our purposes because the refraction of waves affects erosion, transportation, and deposition along the coastline.
