← GeographyWhich crustal extension results when strike-slip faults unlock?
A)Pull-apart basin subsidence Forms✓
B)Orogenic system Thrust Increases
C)Subduction zone Accretion Accelerates
D)Transverse range Uplift Reduces
💡 Explanation
Extensional unlocking generates crustal thinning; normal faulting forms pull-apart basins because the released stress changes fault dynamics rather than simply stopping frictional lock alone. The strain release creates basins, therefore subsidence occurs; rather than compression which creates increased uplift around those faults.
