Resumen: From the moment a granitic magma begins to cool until it is solidified it is\nsubjected to stress and strain, producing the various discontinuities that can be\nseen in the finally exposed rock. When as a result of the erosion of superincumbent\nrocks the granite is at or near the land surface these discontinuities are exploited\nby weathering. Such features, and particularly those related to fractures or\ndiaclases, outline forms that are considered here as primary endogenous forms.\nOnce the rock is in the earth surface, various external agencies first soil\nweathering and later others as gravity, rivers, waves, glaciers, frost, wind, attack\nthe rock to produce new suites of forms that are considered here as primary\nexogenous either etched or subaerial features. Such primary forms, both\nendogenous and exogenous, can evolve morphologically further as a result of\nsubaerial weathering and erosion, becoming secondary endogenous or secondary\nexogenous forms. Exceptionally, some primary, either exogenous or endogenous,\nfeatures can survive to successive morphogenetic episodes either below\nsedimentary burial or just subaerially without appreciable modification by\nexternal agencies being considered as inherited forms. Only the discernment of\nall these types of landforms allows the complete understanding of the\ngeomorphological history of the area in which they occur.
