The Greenland plate is a tectonic microplate bounded to the west by Nares Strait, a probable transform fault; on the southwest by the Ungava transform underlying Davis Strait; on the southeast by the Mid-Atlantic Ridge; [1] and the northeast by the Gakkel Ridge, with its northwest border still being explored. [2]
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] 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.
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]
Map of the principal tectonic plates of the Earth. The sixteen major pieces of crust and uppermost mantle of the Earth, called the lithosphere, and consisting of oceanic and continental crust.
Fault block – Large blocks of rock created by tectonic and localized stresses in Earth's crust; Fault scarp – Small vertical offset on the ground surface; Joint – Type of fracture in rock; Mitigation of seismic motion; Mountain formation – Geological processes that underlie the formation of mountains; Orogeny – The formation of ...
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 ...
Megathrust earthquakes are almost exclusive to tectonic subduction zones and are often associated with the Pacific and Indian Oceans. [5] These subduction zones are also largely responsible for the volcanic activity associated with the Pacific Ring of Fire. [12] Since these earthquakes deform the ocean floor, they often generate strong tsunami ...
