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.

What are the physical features of a coast?
Coasts have many different features, such as caves and cliffs, beaches and mudflats. Tides, waves, and water currents (flow) shape the land to form these coastal features. Some coasts are also changed by the flow of glaciers, which are huge rivers of ice, and lava from volcanoes.
Is beach a sea or ocean?
Unlike the ocean, beaches are landforms. They form a part of the shoreline of several bodies of water may it be a lake, a sea or even an ocean. As a landform, beaches have many particles of different rock types like pebbles, gravels, shingles, cobblestones, and of course sand.

What Are Geological Features? According to the study of topography, the definition of geological features is the details of the Earth’s surface, such as mountains, valleys, rivers, and lakes. The word topography originates from two Greek root words; topo meaning place or location, and graphia meaning to record.
How the beach is formed?
A beach forms when waves deposit sand and gravel along the shoreline. Some beaches are made up of rocks and pebbles. Over time, they are rolled around smooth by the waves.
How is a beach formed geography?
Beaches. Beaches are made up from eroded material that has been transported from elsewhere and then deposited by the sea. For this to occur, waves must have limited energy, so beaches often form in sheltered areas like bays . Constructive waves build up beaches as they have a strong swash and a weak backwash .
