Inselberg
An inselberg or monadnock ( ) is an isolated rock hill, knob, ridge, or small mountain that rises abruptly from a gently sloping or virtually level surrounding plain. In Southern Africa, a similar formation of granite is known as a koppie, an Afrikaans word ("little head") from the Dutch diminutive word ''kopje''. If the inselberg is dome-shaped and formed from granite or gneiss, it can also be called a bornhardt, though not all bornhardts are inselbergs. An inselberg results when a body of rock resistant to erosion, such as granite, occurring within a body of softer rocks, is exposed by differential erosion and lowering of the surrounding landscape. Etymology Inselberg The word ''inselberg'' is a loan word from German, and means "island mountain". The term was coined in 1900 by geologist Wilhelm Bornhardt (1864–1946) to describe the abundance of such features found in eastern Africa. At that time, the term applied only to arid landscape features. However, it has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bornhardt
A bornhardt () is a dome-shaped, steep-sided, bald rock outcropping at least in height and several hundred metres in width. They are named after Wilhelm Bornhardt (1864–1946), a German geologist and explorer of German East Africa, who first described the feature. While ''bornhardt'' was originally used to sometimes denote a type of inselberg (literally island mountain—an isolated dome in an otherwise flat landscape), the term ''bornhardt'' is used in modern literature to refer to domed hills and mountains regardless of isolation; thus, not all bornhardts are inselbergs and not all inselbergs are bornhardts. Bornhardts are commonly composed of igneous rocks, often granites, but examples of gneiss, quartzite and arkose bornhardts exist. The Sugarloaf Mountain of Rio de Janeiro is a typical example of this landform and is the origin of the common bornhardt nickname "sugar loaf". Bornhardts are most easily seen in arid and semi-arid regions, but occur over a wide range ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shield (geology)
A shield is a large area of exposed Precambrian Crystallinity, crystalline igneous rock, igneous and high-grade metamorphic rock, metamorphic rocks that form tectonics, tectonically stable areas. These rocks are older than 570 million years and sometimes date back to around 2 to 3.5 billion years. They have been little affected by tectonic events following the end of the Precambrian, and are relatively flat regions where mountain building, faulting, and other tectonic processes are minor, compared with the activity at their margins and between tectonic plates. Shields occur on all continents. Terminology The term shield cannot be used interchangeably with the term craton. However, shield can be used interchangeably with the term basement (geology), basement. The difference is that a craton describes a basement overlain by a sedimentary rock, sedimentary platform (geology), platform while shield only describes the basement. The term ''shield'', used to describe this type of ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Monadnock
Mount Monadnock, or Grand Monadnock, is a mountain in the town of Jaffrey, New Hampshire. It is the most prominent mountain peak in southern New Hampshire and is the highest point in Cheshire County, New Hampshire, Cheshire County. It lies southwest of Concord, New Hampshire, Concord and northwest of Boston. At , Mount Monadnock is nearly higher than any other mountain peak within and rises above the surrounding landscape. Monadnock's bare, isolated, and rocky summit provides expansive views. It is known for being featured in the writings of Ralph Waldo Emerson and Henry David Thoreau. Mt. Monadnock has long been cited as one of the most frequently climbed mountains in the world. It bears a number of hiking trails, including the Metacomet-Monadnock Trail and the Monadnock-Sunapee Greenway.DeLorme Topo USA 6.0. (2006). Mapping software. Yarmouth, Maine: DeLorme. The summit is barren largely because of fires set by early settlers. The first major fire, set in 1800 to clear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are inselberg, isolated summits, but most occur in mountain ranges. mountain formation, Mountains are formed through tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosystems of mountains: different elevations hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Savannah
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. Four savanna forms exist; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests.Manoel Cláudio da S ...

Wilhelm Bornhardt
Friedrich Wilhelm Conrad Eduard Bornhardt (20 April 1864 Braunschweig - 2 December 1946 Goslar) was a German geologist, engineer and explorer, and was Director of the Berlin College of Mines (Bergakademie) from 1907 to 1916. He explored and set out the groundwork of the geology of German East Africa. His published work consisted of two parts – an account of his travels and his geological findings. In 1896 he set out from Lindi to Lake Malawi where he stayed for ten months undertaking eight exploratory trips of the region. Afterwards he returned to the coast to write up his geology journals. In 1897 he explored the protectorate of Dar es Salaam as far as the Ruvuma Region, the Zanzibar Archipelago and the Usambara Mountains, carrying out some thirteen journeys. In all he covered about and prepared maps of the geology and vegetation of the regions he traversed. Bornhardt documented the existence of coal reserves in present-day Tanzania in 1896 when he explored the Songwe Kiwira ar ...

Hill
A hill is a landform that extends above the surrounding terrain. It often has a distinct summit, and is usually applied to peaks which are above elevation compared to the relative landmass, though not as prominent as Mountain, mountains. Hills fall under the category of slope landforms. Terminology The distinction between a hill and a mountain is unclear and largely subjective, but a hill is universally considered to be not as tall, or as Grade (slope), steep as a mountain. Geographers historically regarded mountains as hills greater than above sea level. In contrast, hillwalkers have tended to regard mountains as peaks above sea level. The ''Oxford English Dictionary'' also suggests a limit of and Whittow states "Some authorities regard eminences above as mountains, those below being referred to as hills." Today, a mountain is usually defined in the UK and Ireland as any summit at least high, while the UK government's Countryside and Rights of Way Act 2000 defined mou ...

Abenaki Language
Abenaki (Eastern: ', Western: ), also known as Wôbanakiak, is an endangered Eastern Algonquian language of Quebec and the northern states of New England. The language has Eastern and Western forms which differ in vocabulary and phonology and are sometimes considered distinct languages. Western Abenaki was spoken in New Hampshire, Vermont, north-western Massachusetts, and southern Quebec. Odanak, Quebec is a First Nations reserve located near the Saint-François River—these peoples were referred to as Saint Francis Indians by English writers after the 1700s. The few remaining speakers of Western Abenaki live predominantly in Odanak and the last fully fluent speaker, Cécile (Wawanolett) Joubert died in 2006. A revitalization effort was started in Odanak in 1994; however, as of 2004 younger generations are not learning the language and the remaining speakers are elderly, making Western Abenaki nearly extinct. Eastern Abenaki languages are spoken by several peoples, incl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
