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 ...
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 ...
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 ...
One example of these areas is in the western Pacific, where the presence of a submerged plate should be impossible, as there’s been no subduction zone nearby in recent geologic history. And yet ...
Thrust tectonics or contractional tectonics is concerned with the structures formed by, and the tectonic processes associated with, the shortening and thickening of the crust or lithosphere. It is one of the three main types of tectonic regime, the others being extensional tectonics and strike-slip tectonics.
Tectonic–climatic interaction is the interrelationship between tectonic processes and the climate system. The tectonic processes in question include orogenesis , volcanism , and erosion , while relevant climatic processes include atmospheric circulation , orographic lift , monsoon circulation and the rain shadow effect .
Despite their appearance, in these instances the fundamental plate-tectonic structure is still an oceanic trench. Some troughs look similar to oceanic trenches but possess other tectonic structures. One example is the Lesser Antilles Trough, which is the forearc basin of the Lesser Antilles subduction zone. [8]
Mauna Loa is the classic example, with a slope of 4°-6°. (The relation between slope and viscosity falls under the topic of angle of repose . [ 12 ] ) A composite volcano or stratovolcano has a more steeply rising cone (33°-40°), [ 13 ] because of the higher viscosity of the emitted material, and eruptions are more violent and less frequent ...
