Physical Geology
A beach is a landform along the shoreline of an ocean, sea, lake, or river that is made up of loose particles such as sand, gravel, pebbles, or cobblestones. Beaches are dynamic environments shaped by the action of waves, tides, and coastal currents, which influence sediment transport and deposition. These factors play a crucial role in determining the beach's shape, size, and stability, making them important features in coastal geography.
