Key Points

• The boundary line between the land and the sea is called a beach.
• A beach is a landform alongside a body of water which consists of loose particles, typically composed of rock, such as sand, gravel, shingle, pebbles, or cobblestones.
• Beaches can be found along the coastlines of oceans, seas, lakes, and rivers.
• They are formed by the action of waves and currents, which deposit and rework sediments along the shore.
• Beaches play a crucial role in coastal ecosystems and are popular recreational areas for human activities such as swimming, sunbathing, and beach sports.

Additional Information

• Coastal Erosion: Beaches are dynamic environments that are subject to erosion and deposition processes. Coastal erosion can lead to the loss of beach areas and can be influenced by natural factors such as storms and human activities like construction.
• Beach Conservation: Efforts to conserve and protect beaches often involve measures to prevent pollution, manage human activities, and restore natural processes. Beach nourishment, where sand is added to eroding beaches, is one method used to combat erosion.
• Ecological Importance: Beaches provide habitat for various species of plants and animals, including nesting sites for sea turtles and breeding grounds for shorebirds. The intertidal zone of beaches is rich in biodiversity.
• Tourism and Economy: Beaches are major attractions for tourism, contributing significantly to the local and national economies. They offer opportunities for various water sports, relaxation, and cultural activities.
