Massif
In geology, a massif ( or ) is a section of a planet's crust that is demarcated by faults or flexures. In the movement of the crust, a massif tends to retain its internal structure while being displaced as a whole. The term also refers to a group of mountains formed by such a structure. In mountaineering and climbing literature, a massif is frequently used to denote the main mass of an individual mountain. The massif is a smaller structural unit of the crust than a tectonic plate, and is considered the fourth-largest driving force in geomorphology. The word is taken from French (in which the word also means "massive"), where it is used to refer a large mountain mass or compact group of connected mountains forming an independent portion of a range. One of the most notable European examples of a massif is the Massif Central of the Auvergne region of France. The Face on Mars is an example of an extraterrestrial massif. Massifs may also form underwater, as with the Atlanti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marojejy National Park
Marojejy National Park () is a national park in the Sava region of northeastern Madagascar. It covers and is centered on the Marojejy Massif, a mountain chain that rises to an elevation of . Access to the area around the massif was restricted to research scientists when the site was set aside as a strict nature reserve in 1952. In 1998, it was opened to the public when it was converted into a national park. It became part of the World Heritage Site known as the Rainforests of the Atsinanana in 2007. "Unique in the world, a place of dense, jungly rainforests, sheer high cliffs, and plants and animals found nowhere else on earth", Marojejy National Park has received plaudits in the ''New York Times'' and ''Smithsonian Magazine'' for its natural beauty and rich biodiversity that encompasses critically endangered members of the silky sifaka. To that end, a global consortium of conservation organizations, including the Lemur Conservation Foundation, Duke Lemur Center and Madagas ...

Aïr Mountains
The Aïr Mountains or Aïr Massif ( tmh, Ayăr; Hausa: Eastern ''Azbin'', Western ''Abzin'') is a triangular massif, located in northern Niger, within the Sahara. Part of the West Saharan montane xeric woodlands ecoregion, they rise to more than and extend over . Lying in the midst of desert north of the 17th parallel, the Aïr plateau, with an average altitude between , forms an island of Sahel climate which supports a wide variety of life, many pastoral and farming communities, and dramatic geological and archaeological sites. There are notable archaeological excavations in the region that illustrate the prehistoric past of this region. The endangered African wild dog (''Lycaon pictus'') once existed in this region, but may now be extirpated due to human population pressures in this region. Geology The Precambrian to Cenozoic Aïr Mountains consist of peralkaline granite intrusions which appear dark in colour (unusual since most granitic masses are lig ...

Massif Central
The (; oc, Massís Central, ; literally ''"Central Massif"'') is a highland region in south-central France, consisting of mountains and plateaus. It covers about 15% of mainland France. Subject to volcanism that has subsided in the last 10,000 years, these central mountains are separated from the Alps by a deep north–south cleft created by the Rhône river and known in French as the ' (literally "Rhône furrow"). The region was a barrier to transport within France until the opening of the A75 motorway, which not only made north–south travel easier, but also opened access to the massif itself. Geography and geology The is an old massif, formed during the Variscan orogeny, consisting mostly of granitic and metamorphic rocks. It was powerfully raised and made to look geologically younger in the eastern section by the uplift of the Alps during the Paleogene period and in the southern section by the uplift of the Pyrenees. The massif thus presents a strongly a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantis Massif
The Atlantis Massif is a prominent undersea massif in the North Atlantic Ocean. It is a dome-shaped region approximately across and rising about from the sea floor. It is located at approximately 30°8′N latitude 42°8′W longitude; just east of the intersection of the Mid-Atlantic Ridge with the Atlantis Transform Fault. The highest point of the massif is around beneath the surface. Description It is believed that the massif was formed underneath the nearby Mid-Atlantic Ridge, but pulled from underneath the ridge during the movement of the plates, about 1.5 to 2 million years ago. Geologic studies of the massif have indicated that it is not composed of the black basalt typical of the ocean floor, but rather of dense green peridotite usually found in the mantle. The central dome is corrugated and striated in a way that is representative of an exposed ultramafic oceanic core complex. An expedition to the area in 1996 made an important advance in the study of the ocean flo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ennedi Plateau
The Ennedi Plateau is located in the northeast of Chad, in the regions of Ennedi-Ouest and Ennedi-Est. It is considered a part of the group of mountains known as the Ennedi Massif found in Chad, which is one of the nine countries that make up the Sahelian belt that spans the Atlantic Ocean to Sudan. The Ennedi is a sandstone bulwark in the middle of the Sahara, which was formed by erosion from wind and temperature. Many people occupied this area, such as hunters and gatherers (5,000-4,000 cal BC) and pastoralists (beginning 4,000 cal BC). The Ennedi area is also known for its large collection of rock art depicting mainly cattle, as these animals were the main source of financial, environmental, and cultural impact. This art dates back nearly 7,000 years ago. Today, two semi-nomadic groups, mainly of the Muslim religion, have permanent villages in the Ennedi during the rainy months and pass through the area during the dry season. They rely on their herds of camels, donkeys, shee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mulanje Massif
The Mulanje Massif, also known as Mount Mulanje, is a large inselberg in southern Malawi. Sapitwa Peak, the highest point on the massif at 3,002 m, is the highest point in Malawi. It lies 65 km east of Blantyre, rising sharply from the surrounding plains of Phalombe and the Mulanje district. Geography Much of the Massif consists of rolling grassland at elevations of 1800–2200 m, intersected by deep forested ravines. It has many individual peaks reaching heights of over 2500 m, including Chambe Peak, the West Face of which is the longest rock climb in Africa. The Massif was formed by the intrusion of magma into the Earth's crust about 130 million years ago. The surrounding rock eroded away over time, leaving behind the erosion-resistant igneous rock of the Mulanje Massif. The first European to report seeing the Massif was David Livingstone in 1859, but archeological investigation reveals evidence of human visits to the Massif from the Stone Age onwards. The el ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Madagascar (the fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of its wildlife is endemic. Human settlement of Madagascar occurred during or before the mid first millennium AD by Austronesian peoples, presumably arriving on outrigger cano ...

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 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through 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 slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable ter ...

French Language
French ( or ) is a Romance languages, Romance language of the Indo-European languages, Indo-European family. It descended from the Vulgar Latin of the Roman Empire, as did all Romance languages. French evolved from Gallo-Romance, the Latin spoken in Gaul, and more specifically in Northern Gaul. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French (Francien) largely supplanted. French was also substratum, influenced by native Celtic languages of Northern Roman Gaul like Gallia Belgica and by the (Germanic languages, Germanic) Frankish language of the post-Roman Franks, Frankish invaders. Today, owing to France's French colonial empire, past overseas expansion, there are numerous French-based creole languages, most notably Haitian Creole language, Haitian Creole. A French-speaking person or nation may be referred to as Francophone in both English and French. French is an official language in ...
