What is the shape of a sand dune? While mountains are made of rock and their shape is fixed, why do you think sand dunes also have a similar shape, even though they are made of sand? Class 7

Answer:

Sand dunes have a curved, wave-like shape. Unlike mountains, which are solid and fixed, sand dunes change shape due to wind. The wind moves sand around, creating their unique forms, but they often settle into similar shapes over time.
