The difference between weathering and erosion is based on whether a rock's location has changed: Weathering degrades a rock without moving it, while erosion carries rocks and soil away from their original locations. This . Enchanted Rock was exposed when tectonic activity initiated the Llano Uplift. Which type of metamorphism is most likely produced in this environment? Deposition is the dropping of sediment by wind, water, ice, or gravity. During that time, different processes alter the minerals of the protolith into a new metamorphic rock. Consult the figure below. 4.9. Mass Wasting - is the downhill movement of sediments under the influence of gravity. Uplift and Subsidence. The area is part of Llano Uplift, a geologic phenomenon packed with a variety of mineral deposits that took more than 1.5 billion years to form. [2][5][6], Within and around the Llano uplift are erosional remnants and down-faulted blocks of Lower Paleozoic sedimentary strata. . consumed or transformed by processes in the rock cycle. They stood well above the surrounding plains long before any . erosion in the llano uplift makes the cliffs look chiseled to were it looks worn away or flat. [16][18][19], The only Mesozoic rocks that are known in the Llano region are those of the Cretaceous system. 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. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This work applies a debris flow generation likelihood model to evaluate the probability of mass movement . Located in the center of the state.

Select the type of lymphatic vessel which consists solely of an endothelium and has one-way flaps that allow interstitial fluid to enter. and Warren, L.E., 1947. Where the Cretaceous rocks rim the Llano uplift, a sharp topographic rise or escarpment is common. They will destrog the excess topography of a mountain belt, converting rocks into sediment. Uplift and Subsidence. Alluvial fans -when a stream flows down hill onto a flat land surface, the sediment forms a fan-shaped deposit. An island of rock excitement adrift in a sea of Cretaceous limestones whose only redeeming value is the oil in them. At their widest, the exposed Precambrian rocks extend about 65 miles (105km) westward from the valley of the Colorado River and beneath a broad, gentle topographic basin drained by the Llano River.
