List Of Rivers By Age
This is a selected list of the oldest rivers on Earth for which there is knowledge about their existence in past times. Determination of age Generally, the age is estimated based primarily upon the age of any mountains it dissects; the age of the sea or ocean to which it eventually outflows can be irrelevant; for example, several rivers of the east side of the Appalachian Mountains are thought to be older than the Atlantic Ocean into which they flow. If a river fully dissects a mountain range, then this generally indicates that the river existed at least at the time that the mountain range rose.

River
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, spr ...

Meuse River
The Meuse ( , , , ; wa, Moûze ) or Maas ( , ; li, Maos or ) is a major European river, rising in France and flowing through Belgium and the Netherlands before draining into the North Sea from the Rhine–Meuse–Scheldt delta. It has a total length of . History From 1301 the upper Meuse roughly marked the western border of the Holy Roman Empire with the Kingdom of France, after Count Henry III of Bar had to receive the western part of the County of Bar (''Barrois mouvant'') as a French fief from the hands of King Philip IV. In 1408, a Burgundian army led by John the Fearless went to the aid of John III against the citizens of Liège, who were in open revolt. After the battle which saw the men from Liège defeated, John ordered the drowning in the Meuse of suspicious burghers and noblemen in Liège. The border remained stable until the annexation of the Three Bishoprics Metz, Toul and Verdun by King Henry II in 1552 and the occupation of the Duchy of Lorraine by ...

Hudson River
The Hudson River is a river that flows from north to south primarily through eastern New York. It originates in the Adirondack Mountains of Upstate New York and flows southward through the Hudson Valley to the New York Harbor between New York City and Jersey City, eventually draining into the Atlantic Ocean at Lower New York Bay. The river serves as a political boundary between the states of New Jersey and New York at its southern end. Farther north, it marks local boundaries between several New York counties. The lower half of the river is a tidal estuary, deeper than the body of water into which it flows, occupying the Hudson Fjord, an inlet which formed during the most recent period of North American glaciation, estimated at 26,000 to 13,300 years ago. Even as far north as the city of Troy, the flow of the river changes direction with the tides. The Hudson River runs through the Munsee, Lenape, Mohican, Mohawk, and Haudenosaunee homelands.

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 befor ...

French Broad River
The French Broad River is a river in the U.S. states of North Carolina and Tennessee. It flows from near the town of Rosman in Transylvania County, North Carolina, into Tennessee, where its confluence with the Holston River at Knoxville forms the beginning of the Tennessee River. The river flows through the counties of Transylvania, Buncombe, Henderson, and Madison in North Carolina, and Cocke, Jefferson, Sevier, and Knox in Tennessee. It drains large portions of the Pisgah National Forest and the Cherokee National Forest. Course The headwaters of the French Broad River are near the town of Rosman in Transylvania County, North Carolina, just northwest of the Eastern Continental Divide near the northwest border of South Carolina. They spill from a 50-foot waterfall called Courthouse Falls at the terminus of Courthouse Creek near Balsam Grove. The waterfall feeds into a creek that becomes the North Fork, which joins the West Fork west of Rosman. South of Rosman, t ...

Chesapeake Bay
The Chesapeake Bay ( ) is the largest estuary in the United States. The Bay is located in the Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula (including the parts: the Eastern Shore of Maryland / Eastern Shore of Virginia and the state of Delaware) with its mouth of the Bay at the south end located between Cape Henry and Cape Charles. With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others surrounding within its watershed. More than 150 major rivers and streams flow into the Bay's drainage basin, which covers parts of six states (New York, Pennsylvania, Delaware, Maryland, Virginia and West Virginia) and all of District of Columbia. The Bay is approximately long from its northern headwaters in the Susquehanna River to its outlet in the Atlantic Ocean. It is wide at its narrowest (between Kent C ...

Alleghenian Orogeny
The Alleghanian orogeny or Appalachian orogeny is one of the geological mountain-forming events that formed the Appalachian Mountains and Allegheny Mountains. The term and spelling Alleghany orogeny was originally proposed by H.P. Woodward in 1957. The Alleghanian orogeny occurred approximately 325 million to 260 million years ago over at least five deformation events in the Carboniferous to Permian period. The orogeny was caused by Africa's collision with North America. At the time, these continents did not exist in their current forms: North America was part of the Euramerica super-continent, while Africa was part of Gondwana. This collision formed the super-continent Pangaea, which contained all major continental land masses. The collision provoked the orogeny: it exerted massive stress on what is today the Eastern Seaboard of North America, forming a wide and high mountain chain. Evidence for the Alleghanian orogeny stretches for many hundreds of miles on the surface from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kanawha River
The Kanawha River ( ) is a tributary of the Ohio River, approximately 97 mi (156 km) long, in the U.S. state of West Virginia. The largest inland waterway in West Virginia, its valley has been a significant industrial region of the state since early in the 19th century. It is formed at the town of Gauley Bridge in northwestern Fayette County, approximately 35 mi (56 km) SE of Charleston, by the confluence of the New and Gauley rivers. It flows generally northwest, in a winding course on the unglaciated Allegheny Plateau, through Fayette, Kanawha, Putnam, and Mason counties, past the cities of Charleston and St. Albans, and numerous smaller communities. It joins the Ohio at Point Pleasant. Paleo-Indians, the earliest indigenous peoples, lived in the valley and the heights by 10,000 BC as evidenced by archaeological artifacts such as Clovis points. A succession of prehistoric cultures developed, with the Adena culture beginning the construction o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New River (Kanawha River)
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 spre ...

Hercynian
The Variscan or Hercynian orogeny was a geologic mountain-building event caused by Late Paleozoic continental collision between Euramerica (Laurussia) and Gondwana to form the supercontinent of Pangaea. Nomenclature The name ''Variscan'', comes from the Medieval Latin name for the district ''Variscia'', the home of a Germanic tribe, the Varisci; Eduard Suess, professor of geology at the University of Vienna, coined the term in 1880. (Variscite, a rare green mineral first discovered in the Vogtland district of Saxony in Germany, which is in the Variscan belt, has the same etymology.) ''Hercynian'', on the other hand, derives from the Hercynian Forest. Both words were descriptive terms of strike directions observed by geologists in the field, ''variscan'' for southwest to northeast, ''hercynian'' for northwest to southeast. The ''variscan'' direction reflected the direction of ancient fold belts cropping out throughout Germany and adjacent countries and the meaning shifted ...
