Unreferenced date December 2007 In geology the term compression refers to a set of stresses directed toward the center of a rock mass. Compressive strength refers to the maximum compressive stress that can be applied to a material before failure occurs. When the maximum compressive stress is in a horizontal orientation, thrust fault ing can occur, resulting in the shortening and thickening of that portion of the crust geology crust . When the maximum compressive stress is vertical, a section of rock will often fail in normal fault s, horizontally extending and vertically thinning a given layer of rock. Compressive stresses can also result in fold geology folding of rocks. Because of the large magnitudes of lithostatic stress in tectonic plate s, tectonic scale deformation geology deformation is always subjected to net compressive stress.

Environmental geology , like hydrogeology , is an applied science concerned with the practical application of the principles of geology in the solving of environmental problems. It is a multidisciplinary field that is closely related to engineering geology and, to a lesser extent, to environmental geography . Each of these fields involves the study of the interaction of humans with the geologic environment, including the biosphere , the lithosphere , the hydrosphere , and to some extent the Earth s atmosphere atmosphere . Environmental geology includes managing geological and hydrogeological resources such as fossil fuel s, mineral s, water molecule water surface and ground water , and land use . studying the earth s surface through the disciplines of geomorphology , and edaphology defining and mitigating exposure of natural hazards on humans managing industrial and domestic waste disposal and minimizing or eliminating effects of pollution , and performing associated activities, often involving litigation.

In geology, eduction is a process in which the Earth crust spreads sideways, exposing deep seated rocks. It is prominent in middle layers of the Himalayas , where gravity pushes the mountains down. Together with a high grade of erosion, this activity brings deep rocks to the surface, many from more than a depth of 100 km.
