Beaches can experience both deposition and erosion. Deposition occurs when sand and sediment are deposited on the beach by waves and currents, building up the beach. Erosion occurs when waves and currents remove sand and sediment from the beach, causing it to shrink or erode.
Waves can erode coastlines by wearing away rocks and cliffs, leading to beach erosion. They also deposit sediments, helping to build up beaches and shorelines. In extreme cases, large storm waves can cause significant damage to coastal infrastructure.
Waves erode a coast by their continuous and repeated actions of swarsh\uprush and retreats\backwash.
Mechanical action.
Waves affect a shoreline by carrying and depositing sediments, which can contribute to erosion or accretion depending on the wave energy and direction. Strong waves can erode the shoreline by carrying away sediments, while gentler waves may deposit sediments, leading to beach formation.
A cave is sometimes created when waves erode a headland.
A beach is formed by both erosion and deposition. Waves erode the coastline by picking up and moving sand and sediment, which then gets deposited along the shoreline to create a beach. Erosion and deposition processes continually shape beaches over time.
The waves and storm surge of a hurricane can cause severe beach erosion. Heavy rain from hurricanes can cause flooding, which can erode river channels and trigger landslides.
A way waves cause erosion: waves wear away the land and erode the surface.
