← GeographyWhich mineral enrichment results when desert deflation lowers elevation?
A)Relative concentration of heavy minerals✓
B)Increased precipitation of carbonate minerals
C)Greater oxidation of iron compounds
D)Decreased cation exchange capacity
💡 Explanation
Heavy minerals accumulate because selective particle removal via deflation leaves larger dense materials; therefore, heavy minerals increasingly compose surface lag deposits, rather than smaller grains enriched by leaching or chemical weathering processes.
