Landforms that indicate faulting: (a) tilted block, blocked drainage of dip-slip fault; (b) truncated landform of
strike-dip fault; (c) triangular facets along scrap of dip-slip fault; (d) horst (A) and graben (B) block faulting
forming rift valleys; (e) offset drainage shows recent horizontal movement of strike-slip fault; (f) lineation in
landform caused by differential erosion along fault zone of strike-slip fault.
