Feb 13, 2024 · 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.

Jul 5, 2020 · What is a beach? The beach is the area between the lowest spring tide level and the point reached by the storm waves in the highest tides. Find out more about landforms of coastal deposition.
May 29, 2018 · A beach is a dynamic environment located where land, sea, and air meet. It may be defined as a zone of unconsolidated sediment (i.e., loose materials) deposited by water, wind, or glaciers along the coast, between the low tideline and the next important landward change in topography or composition.
Though they are often thought of simply as empty expanses of sand, beaches are actually lively ecosystems with most of the life hidden from the human eye. Beaches occur in areas where fairly strong wave action deposits sand, and a lack of strong currents prevents it from being carried away.
Aug 16, 2023 · A variety of factors—including wave energy, tidal range, sediment supply, beach materials, continental-shelf slope and width, and past geologic history (e.g., glaciation, volcanism, and plate movement)—characterize coastal environments.
