Agents of Erosion - transporting materials together with the force of gravity move sediments. 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. Deposition of Cambrian through Cretaceous sediments occurred on the eroded PreCambrian metamorphic and igneous rock of the Texas Hill Country.

It consists of an island-like exposure of Precambrian igneous and metamorphic rocks surrounded by outcrops of Paleozoic and Cretaceous sedimentary strata. By the late Middle Cambrian, the Proterozoic crystalline rocks formed an arid, low-relief landscape, not unlike the topography of the Llano Uplift today. The Cambrian sea spread northward across the eroded surface an area of Precambrian rocks that had a local relief as great as 240 meters (790ft). Sediments produced by the erosion filled some valleys within the park and spilled outside the Hills to the east, forming the layers now visible at Badlands National Park.

During metamorphism, new mineral grains can form that are not found in the protolith. Match. Uplift replaces rocks on Earth's surface lost the process of erosion. 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. What is an example of weathering erosion and deposition in Texas? They will destrog the excess topography of a mountain belt, converting rocks into sediment. As a result, sediments composed of locally derived residuum, often wind-abraded accumulated as a thin, discontinuous cobble conglomerate overlying Precambrian strata at the base of the Moore Hollow Group.

The process is classified into three major categories including: Biological weathering Chemical weathering Physical weathering Biological Weathering . Furthermore, this area has been interpreted as the largest upland bedrock area of the Llano Uplift and the source of siliciclastic flux to earlier Hickory Sandstone deposition (McBride et al., 2002, p. 3). Both are examples of erosion. [23][24], The Llano Uplift region is also called the Central Mineral region of Texas because of the occurrence of the great variety of minerals found in and the numerous ore prospecting pits dug into exposed Precambrian rocks and Lower Paleozoic strata. The term erosion refers to the group of natural processes, including weathering, dissolution, abrasion, corrosion, and transportation, by which material is worn away from Earth's surface to be transported and deposited in other locations. Weathering and erosion are two important geologic processes in the rock cycle that play a major role in modifying the geologic expression of orogenic processes.
