AP human geography physical feature dictionary vocabulary. Rock samples from the Helan Mountains were subjected freeze-thaw cycles under various conditions in laboratory testing, and the mass, elastic wave velocity and unconfined compressive strength were tested. However, over time scales from the seconds it takes a sand grain to roll downhill to the tens of millions of years for a mountain to disappear by erosion, Earth's topography is highly dynamic. 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. Erosion is the process by which rocks, sediments, or soil are moved or carried away. The area is known as the Llano Uplift.

Mountain topography in convergent orogens is the result of the balance between tectonic uplift, subcidence by deposition of sediments and mountain erosionImage Credit: MBG. These processes continually shape the Earth's surface, and generate the sediments that circulate in the Rock Cycle. The main factors that affect deposition include "particle size, shape and density and the velocity of the transporting stream" (Carnicelli par. The Chappell Limestone and Barnett Shale represent episodic early Carboniferous inundations of the Llano region followed its submergence and formation of a carbonate platform within which the Marble Falls Limestone accumulated as a lateral equivalent to deeper water Smithwick Shale. 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.
