GEOLOGY

Detailed explanation-1: -During the process of coastal erosion, waves pound rocks into pebbles and pebbles into sand. Waves and currents sometimes transport sand away from beaches, moving the coastline farther inland. Coastal erosion can have a huge impact on human settlement as well as coastal ecosystems.

Detailed explanation-2: -As such, wave shape may directly influence the potential of the impact to weaken rock and cause erosion. Measurements of impact pressure at coastal cliffs are limited, and the occurrence and influence of this phenomenon is currently poorly constrained.

Detailed explanation-3: -Breaking waves erode the coast by suspending sediment particles or dislodging rocks. Ice, chemical weathering, and mechanical abrasion also aid the erosion of some rocky headlands and sea cliffs. Beach cobbles and sand act as tools that repeatedly strike the rocks and gradually wear them down.

Detailed explanation-4: -Destructive Waves The swash is when a wave washes up onto the shoreline and the backwash is when the water from a wave retreats back into the sea. Destructive waves have stronger backwashes than swashes. This strong backwash pulls material away from the shoreline and into the sea resulting in erosion.

Detailed explanation-5: -If waves are large and frequent, the coastline will erode faster, whereas smaller, less frequent waves will result in a slower-eroding coast.
