Changing short description from "The portion of the total geologic uplift of the mean earth surface that is not attributable to an isostatic response to unloading" to "Geologic uplift of Earth's surface that is attributed to plate tectonics" (Shortdesc helper) |
Linked the word "isostatic" in the first paragraph to the Isostasy page. |

'''Tectonic uplift''' is the [[orogeny|geologic uplift]] of [[Earth#Surface|Earth's surface]] that is attributed to [[plate tectonics]]. While [[Isostasy|isostatic]] response is important, an increase in the mean elevation of a region can only occur in response to tectonic processes of [[crustal thickening]] (such as [[mountain building]] events), changes in the density distribution of the crust and underlying [[Mantle (geology)|mantle]], and flexural support due to the bending of rigid [[lithosphere]].
The effects of [[denudation]] (processes that wear away the earth's surface) should also be considered. Within the scope of this topic, uplift relates to denudation in that denudation brings buried rocks closer to the surface. This process can redistribute large loads from an elevated region to a topographically lower area as well – thus promoting an isostatic response in the region of denudation (which can cause local bedrock uplift). The timing, magnitude, and rate of denudation can be estimated by [[Geologist|geologists]] using pressure-temperature studies.
