"Sand dunes are never stationary."Explain this statement giving reasons

Answer»

Because sand does not transmit ENERGY to adjacent sand particles when wind BLOWS over it, the wind must rise over a stationary hump. In so doing, it is COMPRESSED vertically, so it must speed up. Continued, strong winds can change these rises into undulating dunes that often go far inland.Thank you ❤️Mark as brainliest please ❤️
