The costal plain of an overlapping strata after the development of subsequent streams and the formation of an inner lowland. The remnant of the coastal plain now forms a cuesta ending landward in an inface, and transected by the consequent stream valley.

A coastal plain after elevation and renewed dissection. Two cuestas and two lowlands are now produced from the hard and weak strata, respectively.

A coastal plain after peneplanation. The strata are now beveled across by the peneplain, and the rivers are no longer controlled by the topography.

A coastal plain in the first cycle of erosion. The presence of two hard layers produces a terraced cuesta front. In exceptional cases the upper terrace may weather back with sufficient rapidity to constitute a second cuesta with a lowland of some width between it and the lower cuesta, if the weak stratum between the harder is of sufficient thickness.
