listen to the pronunciation of orogeny
İngilizce - İngilizce
the process of mountain building by the upward folding of the Earth's crust
Mountain-building event, generally one that occurs in a geosyncline. Orogeny tends to occur during a relatively short geologic time frame. It is usually accompanied by folding and faulting of strata and by the deposition of sediments in areas adjacent to the orogenic belt. Orogenies may result from continental collisions, the underthrusting of continents by oceanic plates, the overriding of oceanic ridges by continents, and other causes. See also Acadian orogeny, Alleghenian orogeny, Alpine orogeny, Laramide orogeny, Taconic orogeny. Acadian orogeny Alleghenian orogeny Alpine orogeny Laramide orogeny Taconic Orogeny
A major episode of mountain building
The process of mountain making or upheaval
- the process of forming mountains through structural disturbance of the earth's crust by folding and/or faulting
the process of mountain formation (especially by the upward displacement of the earth's crust)
A period of mountain building
period of mountain-building
{i} formation of mountains, process of mountain formation
The process of formation of mountains, including thrusting, folding, and faulting in the outer and higher layers, and plastic folding, metamorphism and plutonism in the inner and deeper layer
the process of mountain building due to tectonic activity at  or aligned with convergent plate margins
a major mountain-building episode in geologic history
A geologic process which results in the formation of mountain belts
The deformation of the earth's crust to form mountains
An episode of mountain building resulting from the collision of two continents as the last of the oceanic crust between them is subducted and an ocean closes The name derives from the Greek 'Oros' (mountains) and 'Genesis' (birth)
The process of mountain building
In geological history, a period of building up resulting from movements in the earth's crust; creates folding, faulting, and intrusions such as batholiths (domes), dikes (vertical), and sills (horizontal)
A mountain-building period, during which continental crust is thickened by processes associated with the closing of oceans and subsequent collision between continents
the process of mountain building by the upward folding of the Earths crust
or orogenesis the formation of mountains orographic rainfall rainfall that occurs when an airstream is forced to rise over a mountain range outwash sands and gravels deposited by streams of meltwater (water produced by the melting of a glacier) Such material may be laid down ahead of the glacier's snout to form a large flat expanse called an outwash plain overland flow another term for surface runoff of water after rain overpopulation too many people for the resources available in an area (such as food, land, and water)
Acadian orogeny
Mountain-building event that affected the northern portion of the Appalachian Geosyncline from present-day New York to Newfoundland during the Devonian period. The orogeny was most intense in northern New England. Its origin has been ascribed to the collision of the northeastern portion of the North American Plate with western Europe. Evidence for the orogeny includes deformation of pre-Devonian and Devonian rocks
Alleghenian orogeny
formerly Appalachian Revolution Mountain-building event that affected the Appalachian Geosyncline in the late Permian period (c. 286-248 million years ago). The Alleghenian orogeny is most pronounced in the central and southern Appalachian Mountains and produced the different effects in various subregions: compressional folding and faulting of the Valley and Ridge Province, westward thrusting of the Blue Ridge, and folding and minor metamorphism and igneous intrusion in the Piedmont Province. It may have resulted from the collision (see plate tectonics) of the central and southern Appalachian continental margin with that of North Africa in the Permian period
Alpine orogeny
Mountain-building event that affected a broad segment of southern Europe and the Mediterranean region during the middle Tertiary period. It produced intense metamorphism, crumpling of rock strata, and uplift accompanied by faulting. It was responsible for the elevation of the present Alps, from which the name derives, the uplifting of plateaus in the Balkan Peninsula and in Corsica and Sardinia, and volcanic activity in England, France, Iceland, and parts of Italy
Caledonian orogeny
{i} formation of mountains event which took place during the Silurian and Devonian Periods of the Palaeozoic Era (this formation was recorded in the mountains of northern England, Wales, Scotland, Ireland and west Norway)
Laramide orogeny
Series of mountain-building events that affected much of western North America in Late Cretaceous and Early Tertiary time ( 65 million years ago). The Laramide orogeny originally was believed to mark the Cretaceous-Tertiary boundary. It is now considered to have consisted of many separate pulses of deformation that varied in intensity and age from place to place. Laramide rocks, however, were generally created around the Cretaceous-Tertiary time boundary
Taconic Orogeny
Mountain-building event that affected the Appalachian Geosyncline along the eastern coast of the U.S. Evidence for the orogeny is most pronounced in the northern Appalachian Mountains, but its effects can be noted as far away as Tennessee and Georgia. Events ascribed to it include the development of New York's Taconic Range and Vermont's Green Mountains. Originally thought to have occurred at approximately the Ordovician-Silurian boundary ( 443 million years ago), it is now generally considered to have consisted of several pulses from the mid-Ordovician to the early Silurian Period
