Quizplus · Accepted Answer

The exposed bedrock in the background of the figure is most likely the result of particularly resistant rock and/or thin ice left above the ice surface. As the glacier receded, this rock remained uncovered. Isostatic rebound (A) would have caused the land to rise, but would not have affected the formation of bedrock. A mantle hot spot (C) would have melted the glacier in a localized area, but wouldn't explain the specific location of the exposed bedrock in the background. Local wind-blown deposition (D) would have affected surface features, but not bedrock formation.
