Question

Give a geographical reason for the following:

Migratory sand dunes are uncertain and dangerous.

Answer 1

Migratory sand dunes are uncertain and dangerous because they are constantly moving in the direction of the wind. As they shift, they can bury vegetation, towns, and villages, leading to the destruction of agricultural land, homes, and other infrastructure. This unpredictability makes them a hazard to desert life, as their movement is not easily controlled. The migration of sand dunes can be checked by planting vegetation on their windward slope, but without such intervention, they remain a significant threat to the environment and human settlements in desert areas.
