GEOLOGY

Detailed explanation-1: -Beaches are wave-deposited accumulations of sediment located at the shoreline.

Detailed explanation-2: -The accumulation of sediment along a coast produces depositional landforms. A beach consists of sand, gravel, or crushed seashells that have been brought to the body of water by rivers and streams, carried by waves, and deposited on the coast.

Detailed explanation-3: -Sediment is carried by the waves along the coastline. The movement of the material is known as longshore drift . Waves approach the coast at an angle because of the direction of prevailing wind.

Detailed explanation-4: -A beach is a narrow, gently sloping strip of land that lies along the edge of an ocean, lake, or river. Materials such as sand, pebbles, rocks, and seashell fragments cover beaches. Most beach materials are the products of weathering and erosion. Over many years, water and wind wear away at the land.
