Answer 1

Depositional plains formed as a result of action of wind have irregular and undulating surface because of existence of sand dunes and hallows.

Explanation:

Depositional plains formed by the action of wind, such as sand deserts, have an irregular and undulating surface due to the formation of sand dunes (raised mounds of sand) and hollows (low areas between dunes). These features are shaped by the continuous movement of sand by the wind, creating a varied topography.
