Abstract

The movements of the earth's crust can be divided into two general categories of orogenic and epeirogenic movements. The orogeny movement refers to those crust movements that cause rapid deformation of large masses of rocks with short duration of its impact on a geological scale and high intensity; these movements cause faults, folds and mountains. The epeirogenic movements include movements of the earth's crust whose duration of impact is long and whose severity is low, such as downward movement of crust and formation of basins, as well as rise of parts of the crust. The epeirogenic movements cause the seas’ receding and advancing.
