List Of Subranges Of The Appalachian Mountains
The following is a list of subranges within the Appalachian Mountains, a mountain range stretching ~2,050 miles from Newfoundland and Labrador, Canada to Alabama, US. The Appalachians, at their initial formation, were a part of the larger Central Pangean Mountains along with the Scottish Highlands, the Ouachita Mountains, and the Anti-Atlas Mountains. The modern ranges were formed and/or deformed by the Acadian, Caledonian, Alleghenian, Mauritanide and Variscan orogenies with the Alleghenian orogeny being the most notable to the modern Appalachians. The Appalachians are also subdivided by a number of large plateaus and additional subplateus. These are commonly not considered subranges although they do contain some features referred to as mountains which are assigned to both their geographic "range" and the more general Appalachian Mountains. These plateaus, such as the Allegheny Plateau, are considered provinces of the Appalachian Highlands and the mountains assigned to them a ...

Appalachian Highlands
The Appalachian Mountains, often called the Appalachians, (french: Appalaches), are a system of mountains in eastern to northeastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion. The Appalachian chain is a barrier to east–west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east–west. Definitions vary on the precise boundaries of the Appalachians. The United States Geological Survey (USGS) defines the ''Appalachian Highlands'' physiographic division as consisting of 13 provinces: the Atlantic Coast Uplands, Eastern Newfoundland Atlantic, Maritime Acadian Highlands, Maritime Plain, Notre Dame and Mégantic Mountains, Western Newfoundland Mountains, Piedmont, Blue Ridge, Valley and Ridge, St. Lawrence Valley, Appala ...

Highland
Highlands or uplands are areas of high elevation such as a mountainous region, elevated mountainous plateau or high hills. Generally speaking, upland (or uplands) refers to ranges of hills, typically from up to while highland (or highlands) is usually reserved for ranges of low mountains. However, the two terms are sometimes interchangeable. Highlands internationally Probably the best-known area officially or unofficially referred to as ''highlands'' in the Anglosphere is the Scottish Highlands in northern Scotland, the mountainous region north and west of the Highland Boundary Fault. The Highland council area is a local government area in the Scottish Highlands and Britain's largest local government area. Other highland or upland areas reaching 400-500 m or higher in the United Kingdom include the Southern Uplands in Scotland, the Pennines, North York Moors, Dartmoor and Exmoor in England, and the Cambrian Mountains in Wales. Many countries and regions also have areas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upland And Lowland
Upland and lowland are conditional descriptions of a plain based on elevation above sea level. In studies of the ecology of freshwater rivers, habitats are classified as upland or lowland. Definitions Upland and lowland are portions of plain that are conditionally categorized by their elevation above the sea level. Lowlands are usually no higher than , while uplands are somewhere around to . On unusual occasions, certain lowlands such as the Caspian Depression lie below sea level. Upland habitats are cold, clear and rocky whose rivers are fast-flowing in mountainous areas; lowland habitats are warm with slow-flowing rivers found in relatively flat lowland areas, with water that is frequently colored by sediment and organic matter. These classifications overlap with the geological definitions of "upland" and "lowland". In geology an "upland" is generally considered to be land that is at a higher elevation than the alluvial plain or stream terrace, which are considered t ...

Stratigraphic Ridge
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for an extended distance. The sides of the ridge slope away from the narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either side, are called the ridgelines. Ridges are usually termed hills or mountains as well, depending on size. Smaller ridges, especially those leaving a larger ridge, are often referred to as spurs. Types There are several main types of ridges: ;Dendritic ridge: In typical dissected plateau terrain, the stream drainage valleys will leave intervening ridges. These are by far the most common ridges. These ridges usually represent slightly more erosion resistant rock, but not always – they often remain because there were more joints where the valleys formed or other chance occurrences. This type of ridge is generally somewhat random in orientation, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physiographic Region
Physiographic regions of the world are a means of defining Earth's landforms into distinct regions, based upon the classic three-tiered approach by Nevin M. Fenneman in 1916, that separates landforms into physiographic divisions, physiographic provinces, and physiographic sections. Originally used in North America, the model became the basis for similar classifications of other continents, and was still considered valid . Physiography During the early 1900s, the study of regional-scale geomorphology was termed "physiography". Physiography later was considered to be a contraction of "''physi''cal" and "ge''ography''", and therefore synonymous with physical geography, and the concept became embroiled in controversy surrounding the appropriate concerns of that discipline. Some geomorphologists held to a geological basis for physiography and emphasized a concept of physiographic regions while a conflicting trend among geographers was to equate physiography with "pure morphology," se ...

Appalachian Uplands
The Appalachian Uplands is a physiographic region in Canada. It is one of seven physiographic regions in Canada distinguished by its topography and geology. The region includes southern Quebec, Gaspésie, New Brunswick, Nova Scotia, Prince Edward Island and the island of Newfoundland. Physiographic regions and divisions Each physiographic region, subregion and division has its own subregions and divisions—distinguished by topography and geology. Distinctive features Features include Gros Morne National Park and the Newfoundland Highlands in Newfoundland, the Cobequid Mountains, Antigonish Highlands, Cape Breton Highlands The Cape Breton Highlands (french: Plateau du Cap-Breton, gd, Àrd-thalamh Cheap Bhreatainn), commonly called the Highlands, refer to a highland or mountainous plateau across the northern part of Cape Breton Island in the Canadian province of N ..., Nova Scotia Uplands, and the Annapolis Lowlands in Nova Scotia, the New Brunswick Highlands, Notre-Da ...

Physiographic Regions Of The United States
The physiographic regions of the contiguous United States The contiguous United States (officially the conterminous United States) consists of the 48 adjoining U.S. states and the Federal District of the United States of America. The term excludes the only two non-contiguous states, Alaska and Hawaii ... comprise 8 regions, 25 provinces, and 85 sections. The system dates to Nevin Fenneman's paper ''Physiographic Subdivision of the United States'', published in 1917. Fenneman expanded and presented his system more fully in two books, ''Physiography of western United States'' (1931), and ''Physiography of eastern United States'' (1938). In these works Fenneman described 25 provinces and 85 sections of the United States physiography. Physiographic divisions References {{DEFAULTSORT:United States Physiographic Region ...

Yew Mountains
The Yew Mountains are a mountain ridge in Southern West Virginia that locally forms the boundary between the Allegheny Plateau to the northwest and the Ridge-and-Valley Appalachians to the southeast. It is part of the Allegheny Mountains, and contains some of the highest peaks in West Virginia. Its highest point is at Red Spruce Knob near its northern edge, named for the stand of red spruce at its summit, which is also the highest point of the Highland Scenic Highway, and the ninth highest peak in West Virginia. Other peaks include Black Mountain, Jacox Knob, Briery Knob, and Blue Knob. The Cranberry Wilderness of Monongahela National Forest, and the Yew Mountain Center, are within the range. There is a proposal to create a Birthplace of Rivers National Monument in the area. To the southeast, it descends steeply to the Greenbrier River valley, while to the northwest it descends more slowly within the watershed of the Gauley River. At its northeastern end, the uppermost course ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
