See also:COAST (from See also:Lat. See also:costa, a See also:rib, See also:side) , the See also:part of the See also:land which meets the See also:sea in a See also:line of more or less See also:regular See also:form . The word is sometimes applied to the See also:bank of a See also:river or See also:lake, and sometimes to a region (cf . See also:Gold See also:Coast, Coromandel Coast) which may include the See also:hinterland . If the coast-line runs parallel to a See also:mountain range, such as the See also:Andes, it has usually a more regular form than when, as in the rias coast of See also:west See also:Brittany, it crosses the crustal folds . Again, a recently elevated coast is more regular than one that has been See also:long exposed to See also:wave See also:action . A recently depressed coast will show the irregularities that were impressed upon the See also:surface before submergence . Wave erosion and the action of marine currents are the See also:chief agents in coast See also:sculpture . A coast of homogeneous See also:rock exposed to similar action will See also:present a regular outline, but if exposed to See also:differential action it will be embayed where that action is greatest . A coast consisting of rocks of unequal hardness or of unequal structure will present headlands, " stacks " and " needles " of hard rocks, and bays of softer or more loosely aggregated rocks, when the wave and current action is similar throughout . The See also:southern See also:shore-line of the Isle of See also:Wight and the western coast of See also:Wales are See also:simple examples of this differential resistance . In See also:time the coast becomes " mature " and its outline undergoes little See also:change as it gradually recedes, for the hard rock being now more exposed is worn away faster, but the softer rock more slowly because it is protected in the bays and re-entrants . |
