Question
The Blue Ridge Mountain range is located in the eastern United States, starting at its southernmost portion in Georgia, then ending northward in Pennsylvania. To the west of the Blue Ridge, between it and the bulk of the Appalachians, lies the Great Appalachian Valley, bordered on the west by the Ridge and Valley province of the Appalachian range. The Blue Ridge is an assembly of several stacked thrust sheets, each with distinctive rock types. A thrust sheet in the continental crust is a large slice of rock that has been pushed up and over other rocks along a thrust fault. Thrust faults form in response to compression during mountain building, and once formed, they provide the break along which thrust sheets move.
Consider the information in the passage above. If this is accurate, what type of rocks should dominate the Blue Ridge area to confirm this scenario?
Responses
A metamorphicmetamorphic
B sedimentarysedimentary
C igneous extrusiveigneous extrusive
D extrusive granite

To confirm the scenario described in the passage about the Blue Ridge Mountain range being an assembly of several stacked thrust sheets formed due to compression during mountain building, the dominant type of rocks should be:
A) metamorphic
Metamorphic rocks are typically formed from existing rock types through heat and pressure, which aligns with the geological processes described in the formation of thrust sheets in mountainous regions like the Blue Ridge.
