Endogenic and Exogenic Factors
Endogenic (or endogenetic) factors are agents supplying energy for actions that are located within the earth. Endogenic factors have origins located well below the earth’s surface. The term is applied, for example, to volcanic origins of landforms, but it is also applied to the original chemical precipitates. Exogenic (or exogenetic) factors are agents supplying energy for actions that are located at or near the earth’s surface. Exogenic factors are usually driven by gravity or atmospheric forces. The term is commonly applied to various processes such as weathering, denudation, mass wasting, etc. In coastal science, these factors may be illustrated in two significant applications. One is the classification of coastlines and the other is the discussion of sea-level variations.
Factors in coastline classification
As early as 1885, Suess (as cited in Kennet, 1982) described the fundamental difference between the coastlines of the Atlantic and those of the Pacific Ocean. This distinction...
