Theoretically, a tectonic weapon functions by creating a powerful charge of elastic energy in the form of deformed volume of the Earth's crust in a region of tectonic activity. [2] This then becomes an earthquake once triggered by a nuclear explosion in the epicenter or a vast electric pulse. [2]
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 Canary Islands are on the African tectonic plate but they are far from the plate's edges; this controls the type of volcanic activity, known as intraplate volcanism, that has formed the islands. [1] The Canary Islands, and some associated underwater volcanic mountains on the ocean floor, are in the Canary Volcanic Province.
Mid-ocean ridge – Basaltic underwater mountain system formed by plate tectonic spreading; Oceanic basin – Geologic basin under the sea; Oceanic plateau – Relatively flat submarine region that rises well above the level of the ambient seabed; Oceanic ridge – An underwater mountain system formed by plate tectonic spreading
The Wilson cycle theory is based upon the idea of an ongoing cycle of ocean closure, continental collision, and a formation of new ocean on the former suture zone.The Wilson Cycle can be described in six phases of tectonic plate motion: the separation of a continent (continental rift), formation of a young ocean at the seafloor, formation of ocean basins during continental drift, initiation of ...
The Hanging Hills of Connecticut (Metacomet Ridge range); upfaulting visible from right to left. Horizontal movement between blocks along a strike-slip fault. Fault blocks are very large blocks of rock, sometimes hundreds of kilometres in extent, created by tectonic and localized stresses in Earth's crust.
Map of the later North Atlantic region after the closing of the Iapetus Ocean and the Caledonian/Acadian orogenies (Wilson 1966).Animals: Trilobites and graptolites. [1] [2] Euramerica in the Devonian (416 to 359 Ma) with Baltica, Avalonia (Cabot Fault, Newfoundland and Great Glen Fault, Scotland; cited in Wilson 1962) and Laurentia (Other parts: Iberian Massif and Armorican terrane).
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') is the scientific theory that Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
