← GeographyWhich outcome is directly enhanced due to differential cementation?
A)Formation of petrified deflation surfaces✓
B)Ventifact abrasion resistance gradient
C)Enhanced loess deposit stability
D)Barchan dune migration velocity
💡 Explanation
The formation of petrified deflation surfaces follows directly via differential cementation; varied mineral precipitation binds exposed sediments while less-cemented sediment erodes, due to selective weathering. Therefore, resistant layers form a protective cap rather than uniformly eroding surfaces.
