INDIAN GEOGRAPHY

Detailed explanation-1: -A dune is a mound of sand formed by the wind, usually along the beach or in a desert. Dunes form when wind blows sand into a sheltered area behind an obstacle. Dunes grow as grains of sand accumulate.

Detailed explanation-2: -A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes with little or no vegetation are called ergs or sand seas.

Detailed explanation-3: -A sand dune is a hill or ridge beyond the reach of the tides, formed from sand over many years. They are ever-changing structures. Dunes usually form in bands parallel to the beach, getting taller and more chaotic the further away you get.

Detailed explanation-4: -A hill or. ridge of sand piled up by the wind is called a sand dune. Dunes may form wherever there is a lot of loose sand and enough wind to move it. Beaches and deserts are common places for dunes.

Detailed explanation-5: -Sand dunes are created when wind deposits sand on top of each other until a small mound starts to form. Once that first mound forms, sand piles up on the windward side more and more until the edge of the dune collapses under its own weight.
