Firth – Scottish word used for various coastal inlets and straits; Fjard – Glacially formed, broad, shallow inlet; Fjord – Long, narrow inlet with steep sides or cliffs, created by glacial activity; Geo – Inlet, a gully or a narrow and deep cleft in the face of a cliff; Gulf – Large inlet from the ocean into the landmass List of gulfs
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 word "tectonic" comes from Ancient Greek: τεκτων, "carpenter, builder" that eventually led to master builder, ἀρχιτέκτων (now architect).First application to modern architecture belongs to Karl Otfried Müller, in Handbuch der Archaologie der Kunst (Handbook of the Archeology of Art, 1830) he defined the art forms that combine art with utility (from utensils to dwellings ...
This is a list of tectonic plates on Earth's surface. Tectonic plates are pieces of Earth's crust and uppermost mantle , together referred to as the lithosphere . The plates are around 100 km (62 mi) thick and consist of two principal types of material: oceanic crust (also called sima from silicon and magnesium ) and continental crust ( sial ...
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 ...
It is important to know if the tectonic phase was a longer event or if it was local or regional. Tectonic phases can be important events that affected large areas. The Alleghenian orogeny in North America (during the Carboniferous period) for example can be found as an angular unconformity between rock layers in large parts of that continent.
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.
Large crustal blocks broken off from tectonic plates are called terranes. [1] Those terranes which are the full thickness of the lithosphere are called microplates. Continent-sized blocks are called variously microcontinents, continental ribbons, H-blocks, extensional allochthons and outer highs.
