  • Descrição: Mountains are shaped by the movement of tectonic plates under the earth's surface, and by the power of climate and erosion. Together, these forces shape the mountain itself and determine the time frame in which a range is built or eroded. Erosion, once considered a lesser force than tectonics, is now considered of greater impact. The Geographic Cycle model of mountain evolution, developed in 1899, was replaced by the plate-tectonics model in the 1960s. This model still best explains the distribution of mountains across the world, and the constructive results of mass and heat applied to the earth's crust. A systems model of mountains adds the effects of climate and erosion, which explain the removal and transport of sediment, and the conditions which accelerate this process. This model requires that both the components of the system and their interaction be considered. Feedback within the system occurs through isostasy, among other loops.
