Just like rivers deposit sand and rocks, the sea also deposits materials (sand, pebbles, and rock debris) when waves and currents slow down.
What Are Marine Depositional Landforms? Just like rivers deposit sand and rocks, the sea also deposits materials (sand, pebbles, and rock debris) when waves and currents slow down. This creates different coastal landforms over time. 1️⃣ Beach – The Shoreline of Sand and Pebbles When waves bring sand and small rocks and deposit them on the coast, a beach is formed. This is a temporary landform because strong waves can wash away the sand. Example: Goa Beaches (India), Miami Beach (USA) . 2️⃣ Bar – A Submerged Sandbank in the Sea Sometimes, waves and tides deposit sand and pebbles under the water, forming a long ridge away from the shore. This remains underwater and is called a bar . The water trapped between the bar and the coast forms a lagoon (a shallow waterbody). Example: Chilika Lake (India), Pulicat Lake (India) (both are lagoons formed due to bars). 3️⃣ Barrier – A Bar That Stays Above Water If a bar rises above water , it is called a barrier . It acts like a natural wall , protecting the land fro…
