be terraced, indicating differential weathering due to differences in rock type. Interbedded sedimentary rocks
made up of thin horizontal layers are less likely to exhibit this stair-stepped topography, although very narrow
terraces may follow the hillside contours in arid regions. In any case, the more resistant rock types, such as
sandstone (and limestone in arid environments) comprise the caprock of the hills, while the weaker rocks, such as
shale, occupy the lowlands. Figure 1-14 shows landforms developed on the flat-lying interbedded sedimentary
rocks of the Colorado Plateau.
