Which outcome occurs when vegetation cover declines at dunes?

💡 Explanation

Increased dune migration happens because less vegetation leads to reduced surface friction and increased wind transport of the sand during aeolian processes; therefore, the dune moves faster rather than reduced migration or mineral precipitation being affected in isolation.
