D)Extensive playas ringed by large sand dunes

Question

Quizplus · Accepted Answer

A geologically recent fault block mountain uplift would have a flat upland surface due to recent uplift, steep slopes created from the uplift, and small alluvial fans due to the lack of time for significant erosion and deposition. Large, broad bajadas with many inselbergs are more commonly associated with longer-term erosion processes. Small playas and large alluvial fans are associated with arid environments, but not specifically with fault block mountains. Extensive playas ringed by large sand dunes are more commonly found in desert regions with strong wind patterns.
