Answer 1

They cover all surfaces with thick layers of sand.

Explanation:

Migratory dunes are sand dunes that move due to the action of wind. As they shift, they can cover large areas with thick layers of sand, which can damage towns and villages by burying homes, roads, and other infrastructure. This process can disrupt daily life, damage crops, and make the area uninhabitable.
