← GeographyFollowing subduction of the Juan de Fuca plate, which outcome characterizes deformation inland?
A)Crustal thickening via ductile shortening✓
B)Widespread normal-fault block subsidence
C)Extensive magma intrusion ceases entirely
D)Limited strike-slip and minimal uplift
💡 Explanation
Crustal thickening occurs because compression from plate convergence results in ductile shortening accommodated through folding and thrust faulting of the continental crust rather than widespread faulting. Therefore, crustal thickening dominates, rather than subsidence due to normal faults.
