This is an example of. June 8, 2022 llano uplift weathering, erosion, and deposition. Sedimentation occurs when eroded material that is being transported by water, settles out of the water column onto the surface, as the water flow slows. Emphasis is on how the appearance of land features (such as mountains, valleys, and plateaus) and sea-floor features (such as trenches, ridges, and seamounts) are a result of both constructive forces (such as volcanism, tectonic uplift, and orogeny) and destructive mechanisms (such as weathering, mass wasting, and coastal erosion). Under these conditions, gravity acts by erosion . The subdued topographic basin is underlain by Precambrian rocks and bordered by a discontinuous rim of flat-topped hills. The Enchanted Rock experiences a type of physical weathering called exfoliation. Understanding the idea of Uplift is the key to making sense of the rock cycle, as it allows us to see rocks that were once deeply buried beneath the surface.
