Normal faults are found in a variety of sizes: some are small, having displacements of only a meter or so, like the one shown in the road cut in Figure 10.10. Others extend for tens of kilometers where they may sinuously trace the boundary ofa mountain front. Most large, normal faults have relatively steep dips that tend flatten out with depth. Vertical displacements along dip-slip faults may produce long, low cliffs called scarps (Figure 10.12).
