Texas Ecoregions and Weathering, Deposition, and Erosion Edwards Plateau and Llano Uplift What factors about climate, soil, geography, or vegetation, could affect weathering, . Q. . Mass Wasting - is the downhill movement of sediments under the influence of gravity. The term topography is used to describe the changes in elevation over a particular area and is, generally speaking, the result of two processes: deposition and erosion. Physical Weathering Enchanted Rock in the Llano Uplift Ecoregion Exfoliation-warming and cooling of rocks over time causes rocks to peel into sheets . What Texas state park in the Llano . 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). The Influence of Bedrock on a Landscape. Weathering, Erosion, and Deposition: Post Oak Savannah. 515 Ma). 9 . The Enchanted Rock experiences a type of physical weathering called exfoliation. An unusual landform in this ecoregion is a dome of granite called Enchanted Rock. The Llano Uplift is a rock hound's wonderland. The massive Enchanted Rock granite batholith is 1.083 billion years old (Precambrian). 42 terms. What type of land formation would you expect to find where the river deposits sediments as it. A relatively large unit of land or water that is characterized by a distinctive climate, ecological features, and plant and animal communities Regions of Texas rock deposition. 42 terms.

Since the Edwards Plateau is composed of large amounts of limestone rock formations with a vast underground cave system. The Llano Uplift is a geologically ancient, low geologic dome that is about 90 miles (140 km) in diameter and located mostly in Llano, Mason, San Saba, Gillespie, and Blanco counties, Texas. Hurricanes and other strong storm systems are main culprits behind coastal flooding. Uplift of the Black Hills and the Central Texas Uplift began as the continental interior was raised and the last Cretaceous sea was displaced, 65 to 70 million years ago.
