Extensional tectonics is associated with the stretching and thinning of the crust or the lithosphere.This type of tectonics is found at divergent plate boundaries, in continental rifts, during and after a period of continental collision caused by the lateral spreading of the thickened crust formed, at releasing bends in strike-slip faults, in back-arc basins, and on the continental end of ...
The Vasquez Rock formations, located in the Sierra Pelona Mountains, were formed by tectonic activity along an offshoot of the San Andreas Fault.. Morphotectonics (from Ancient Greek: μορφή, morphḗ, "form"; [1] and τεκτονικός, tektonikos, "pertaining to building" [2]), or tectonic geomorphology, is a branch of geomorphology that studies how landforms are formed or affected by ...
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 ...
The word is derived from the Greek διαστροϕή diastrophḗ 'distortion, dislocation'. [1] Diastrophism covers movement of solid (plastic) crust material, as opposed to movement of molten material which is covered by volcanism. Movement causes rock to be bent or broken.
Tectonophysics is concerned with movements in the Earth's crust and deformations over scales from meters to thousands of kilometers. [2] These govern processes on local and regional scales and at structural boundaries, such as the destruction of continental crust (e.g. gravitational instability) and oceanic crust (e.g. subduction), convection in the Earth's mantle (availability of melts), the ...

This word refers to a wedge-shaped block that's placed against a wheel to prevent it from moving. It's commonly used on larger vehicles. OK, that's it for hints—I don't want to totally give it ...
Tectonic plates are able to move because of the relative density of oceanic lithosphere and the relative weakness of the asthenosphere. Dissipation of heat from the mantle is the original source of the energy required to drive plate tectonics through convection or large scale upwelling and doming.
