Abstract

The earth has a very complex and variable surface. Its terrain shapes and compositional materials reflect rocky substrates and non-solid materials that are located in the lower part of the earth and always cause changes on the surface of the earth following changes in internal factors. Any type of rocks, cracks or fractures is caused by internal movements of the earth, and any erosive or sedimentary feature is a process that has led to their creation.
