Which consequence results when sand supply decreases forming dunes?

💡 Explanation

Increased dune migration occurs when sand supply decreases because the dune mass is reduced, therefore wind more easily moves a diminished volume with less cohesion via deflation, rather than maintaining stable positioning within space; other processes become locally constrained.
