← GeographyWhich environmental outcome occurs when dust deflation impacts soil?
A)Regolith armor formation✓
B)Clay mineral aggregation
C)Increased soil carbon sequestration
D)Enhanced soil water retention
💡 Explanation
Dust storms lead to regolith armor formation because deflation selectively removes fine particles, causing the concentration of larger, wind-resistant pebbles and rocks on the surface via armoring; therefore, it forms a protective crust rather than altering the mineral assembly.
