Forcing Variable: The Tectonic System. Breccias found at the base of the base of the pockets of Devonian strata likely represent a mixture of residuum developed by the subaerial, in situ dissolution of underlying limestones and dolomites and residuum eroded and redeposited by an advancing marine shoreline. Since that uplift, weathering, erosion and minor uplifting have been shaping the Black Hills. Barnes, V.E., Cloud Jr, P.E. 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. Post-fire geomorphic processes and associated risks are an important threat in Mediterranean environments. Transportation and deposition occur through the action of glaciers, streams, waves, wind, and other agents, and sediments are deposited in rivers, lakes, deserts, and the ocean. Under these conditions, gravity acts by erosion, redistributing mass from higher altitudes to lower elevations in search of equilibrium defined by the base level. The massive Enchanted Rock granite batholith is 1.083 billion years old (Precambrian). .
