Detailed explanation-1: -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.

Detailed explanation-2: -Coastal erosion is the breaking down and carrying away of materials by the sea. Deposition is when material carried by the sea is deposited or left behind on the coast. Coastal erosion takes place with destructive waves. These destructive waves are very high in energy and are most powerful in stormy conditions.

Detailed explanation-3: -Beach erosion occurs when wind and water remove sand from the beach and move it to other locations. Severe erosion leads to flooding, building loss, and road damage.

Detailed explanation-4: -There are four main processes of coastal erosion. These are corrasion, abrasion, hydraulic action and attrition.

Detailed explanation-5: -The erosion and alteration of beach geology occurs through natural processes, such as wave action and extreme weather events. Where the wind conditions are correct, the beaches can be supported by coastal dunes that provide protection and uplift for the coastline.
