Explanation

Inselberg (German for 'island mountain') is a residual hill that stands isolated in a desert landscape, resistant to erosion while surrounding material weathers away. These are typically hard rock outcrops (often granite) that remain after softer material erodes. Inlier (A) is younger rock surrounded by older; playa (C) is a desert lake bed; pediment (D) is a sloping plain at mountain base.
