← GeographyWithin desert ecosystems, which outcome results when surface cohesion decreases and wind velocity increases?
A)Increased ventifact formation by abrasion✓
B)Parabolic dune formation by vegetation
C)Formation of alluvial fans diminishes
D)Rain shadow shifts toward leeward slopes
💡 Explanation
Increased 'deflation' occurs, because winds erode less consolidated surfaces via particle detachment and transport; therefore ventifact formation increases, rather than dune formation, which is a depositional process occurring with vegetation influence or deposition slowdown.
