A study of maps of the world's coastlines suggests that the apparently unlimited variety of coastal configurations falls into a relatively small number of repeating patterns. Considerable thought has gone into coastal classifica- tion, and the reader is referred to the excellent summary of existing classifications presented by C. A. M. King (1972; also Chapter 15) .The operational classification that is used in this text is presented in Table 2 and Fig. 19. The most basic practicable division appears to be into coasts with substrates of crystalline or lithified sedimen- tary rock versus coasts bordering coastal plains, with substrates of unlithified sediment. Both lithified and un- lithified coasts may adjust their configurations in re- sponse to the coastal wave climates but they do so at different rates, and in response to somewhat different mechanisms. Patterns of sedimentation may be relatively simple on straight rocky coasts, but coasts of structured rock may be so deeply embayed as to greatly complicate the pattern (crenulate rocky coasts). Unconsolidated coasts are floored by easily eroded and flat-lying strata, and the surficial sediment tends to be both abundant in quantity and continuous in extent. On such coasts, wave-driven currents in the littoral zone and wind- or tide-driven currents farther offshore tend to build straight coastal segments of the sediment avail- able to them. A b
