New River (Kanawha River Tributary)
The New River is a river which flows through the U.S. states of North Carolina, Virginia, and West Virginia before joining with the Gauley River to form the Kanawha River at the town of Gauley Bridge, West Virginia. Part of the Ohio River watershed, it is about long. The origins of the name are unclear. Possibilities include being a new river that was not on the Fry-Jefferson map of Virginia, an Indian name meaning "new waters", or the surname of an early settler. It was once called Wood's River for Colonel Abraham Wood, an English explorer from Virginia, who explored the river in the mid-17th century. Despite its name, the New River is one of the five oldest rivers in the world geologically. However this claim is disputed by the West Virginia Geological and Economic Survey and the National Park Service. This low-level crossing of the Appalachians, many millions of years old, has long been a biogeographical corridor allowing numerous species of plants and animals to spread ...

Tennessee River
The Tennessee River is the largest tributary of the Ohio River. It is approximately long and is located in the southeastern United States in the Tennessee Valley. The river was once popularly known as the Cherokee River, among other names, as the Cherokee people had their homelands along its banks, especially in what are now East Tennessee and northern Alabama. Additionally, its tributary, the Little Tennessee River, flows into it from Western North Carolina and northeastern Georgia, where the river also was bordered by numerous Cherokee towns. Its current name is derived from the Cherokee town, ''Tanasi'', which was located on the Tennessee side of the Appalachian Mountains. Course The Tennessee River is formed at the confluence of the Holston and French Broad rivers in present-day Knoxville, Tennessee. From Knoxville, it flows southwest through East Tennessee into Chattanooga before crossing into Alabama. It travels through the Huntsville and Decatur area before rea ...

Tennessee Valley Divide
The Tennessee Valley Divide is the boundary of the drainage basin of the Tennessee River and its tributaries. The Tennessee River drainage basin begins with its tributaries in southwestern Virginia and flows generally west to the confluence of the Tennessee with the Ohio River at Paducah, Kentucky. The Tennessee Valley Divide forms a loop surrounding the drainage basin, beginning and ending at the river's mouth in Paducah. Following the Divide in a clockwise direction, it leads east and southeast through western Kentucky through the Land Between the Lakes, a narrow area between the Tennessee River and Cumberland River, then passes into Tennessee, where it continues southeast, passing south of the Nashville Basin on top of Duck River Ridge. Turning more to the east, the Divide climbs onto the low plateau of The Barrens, and then onto the higher Cumberland Plateau. The Divide turns northeast along the crest of the Cumberland Plateau, then follows the ridgecrest of Cumberland Mount ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...

Paleozoic
The Paleozoic (or Palaeozoic) Era is the earliest of three geologic eras of the Phanerozoic Eon. The name ''Paleozoic'' ( ;) was coined by the British geologist Adam Sedgwick in 1838 by combining the Greek words ''palaiós'' (, "old") and ''zōḗ'' (), "life", meaning "ancient life" ). It is the longest of the Phanerozoic eras, lasting from , and is subdivided into six geologic periods (from oldest to youngest): # Cambrian # Ordovician # Silurian # Devonian # Carboniferous # Permian The Paleozoic comes after the Neoproterozoic Era of the Proterozoic Eon and is followed by the Mesozoic Era. The Paleozoic was a time of dramatic geological, climatic, and evolutionary change. The Cambrian witnessed the most rapid and widespread diversification of life in Earth's history, known as the Cambrian explosion, in which most modern phyla first appeared. Arthropods, molluscs, fish, amphibians, reptiles, and synapsids all evolved during the Paleozoic. Life began in the ocean ...

NatureServe Conservation Status
The NatureServe conservation status system, maintained and presented by NatureServe in cooperation with the Natural Heritage Network, was developed in the United States in the 1980s by The Nature Conservancy (TNC) as a means for ranking or categorizing the relative imperilment of species of plants, animals, or other organisms, as well as natural ecological communities, on the global, national or subnational levels. These designations are also referred to as NatureServe ranks, NatureServe statuses, or Natural Heritage ranks. While the Nature Conservancy is no longer substantially involved in the maintenance of these ranks, the name TNC ranks is still sometimes encountered for them. NatureServe ranks indicate the imperilment of species or ecological communities as natural occurrences, ignoring individuals or populations in captivity or cultivation, and also ignoring non-native occurrences established through human intervention beyond the species' natural range, as for example w ...
