Question

sand particles that blow with the wind are of different shapes and sizes give reason ​

Answer 1

Answer:

Dune sands are usually very uniform in size and shape. Particles are sand-sized, because larger particles are too heavy for the wind to transport by suspension. ... As the wind moves up and over the obstacle, it increases in speed. It carries the sand grains up the gently sloping, upwind side of the dune by saltation.
