Weathering and Erosion | Geology | | Course Hero (A heretical view hereabouts). Uplift (as vertical motion of the surface with respect to a reference level, for example the geoid) and exhumation (defined as vertical motion of rocks with respect to the surface) may follow different patterns in time and that the difference between the two evolutions may be a useful indicator of the exhumation process. The removal by erosion of large volumes of rock from high altitude and its deposition elsewhere can result in a lightening of the load on the lower crust and mantle that can cause isostatic uplift. These hills are the dissected edge of the Edwards Plateau, which consist of overlying Cretaceous sedimentary strata. [20], By the time that the regions of the Llano Uplift was slowly covered by Cretaceous sedimentary deposits, it had been reduced by erosion to a low relief erosion surface termed the Wichita paleoplain. local vegetation.
