Exhumation by tectonic processes refers to any geological mechanism that brings rocks from deeper crustal levels to shallower crustal levels. While erosion or denudation is fundamental in eventually exposing these deeper rocks at the Earth's surface, the geological phenomenon that drive the rocks to shallower crust are still considered exhumation processes.
The displacement of rocks with respect to the surface is called exhumation. This simple equation relates the three kinds of displacement: Surface uplift = uplift of rock – exhumation. The term geoid is used above to mean mean sea level and makes a good frame of reference. A given displacement within this frame of reference allows one to ...
Advanced Placement (AP) Human Geography (also known as AP Human Geo, AP Geography, APHG, AP HuGe, APHug, AP Human, HuGS, AP HuGo, or HGAP) is an Advanced Placement social studies course in human geography for high school, usually freshmen students in the US, culminating in an exam administered by the College Board.

Ultra-high-pressure metamorphism refers to metamorphic processes at pressures high enough to stabilize coesite, the high-pressure polymorph of SiO 2.It is important because the processes that form and exhume ultra-high-pressure (UHP) metamorphic rocks may strongly affect plate tectonics, the composition and evolution of Earth's crust.
Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...
[1] [2] It is crucial in the early stage of a geological mapping as it is less time-consuming and offers important data at a minimal price. [1] It is also commonly used in other industries such as forest management , environmental science , disciplines of engineering, and investigating aviation accidents .
Subsidence frequently causes major problems in karst terrains, where dissolution of limestone by fluid flow in the subsurface creates voids (i.e., caves).If the roof of a void becomes too weak, it can collapse and the overlying rock and earth will fall into the space, causing subsidence at the surface.
Tectonic Burial is the deformation of rocks caused by extreme pressure over millions of years. [1] It often causes temperature evolutions and deep burials. [2] Tectonic burial is usually the result of continental collisions or subduction in a region. [3]
