Mount Tahat
Mount Tahat ( ar, جبل تاهات) is the highest mountain peak in Algeria. It sits at an elevation of 2,908 metres (9,541 ft). Other sources indicate an elevation of . Tahat is also the highest peak in the Hoggar Mountains. Its nearest city is Tamanrasset which is located to the south. Mount Tahat is of volcanic origin. It is located in an arid, rocky high plateau area of the central Sahara Desert. The Tuareg inhabit this region. To the north lie the Tassili n'Ajjer mountains, which contain cave paintings dating from a period between 8000 and 2000 BC. The rock art is pastoral, showing cattle breeding and hunting of animals that are today exclusively found in the southern Sahara's climate.

Topographic elevation is the vertical distance above the reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface. Table }) is a salt lake on the border between Turkmenistan and Uzbekistan which dries into salt ponds and can eventually leave a salt flat with an elevation as low as in Turkmenistan.

Cave Painting
In archaeology, Cave paintings are a type of parietal art (which category also includes petroglyphs, or engravings), found on the wall or ceilings of caves. The term usually implies prehistoric origin, and the oldest known are more than 40,000 years old (art of the Upper Paleolithic), found in the caves in the district of Maros ( Sulawesi, Indonesia). The oldest are often constructed from hand stencils and simple geometric shapes.M. Aubert et al., "Pleistocene cave art from Sulawesi, Indonesia", ''Nature'' volume 514, pages 223–227 (09 October 2014). "using uranium-series dating of coralloid speleothems directly associated with 12 human hand stencils and two figurative animal depictions from seven cave sites in the Maros karsts of Sulawesi, we show that rock art traditions on this Indonesian island are at least compatible in age with the oldest European art. The earliest dated image from Maros, with a minimum age of 39.9 kyr, is now the oldest known hand stencil in the world. In ...

Mountains Of Algeria
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 terrain and ...

Volcanoes Of Algeria
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide pa ...

Atakor Volcanic Field
Atakor volcanic field ("Atakor" in Tuareg means "swollen part, knot at the end of something") is a volcanic field in Algeria. It lies in the Hoggar mountains and consists of a variety of volcanic features such as lava flows and about 450 individual vents which create a spectacular scenery. Atakor is one of several large volcanic fields in this mountain range, which sits atop of a domal uplift and has erupted basalt, trachyte and phonolite. Volcanism in Atakor took place in several different phases, beginning 20 million years ago and continuing into the Holocene. Presently there is fumarolic activity. Geography and geomorphology The field lies in the Hoggar and the terrain approaches elevations of although the volcanics form an only superficial cover. The ground has a desert-like appearance. The scenery of the volcanic field is considered to be spectacular, with the lava domes and volcanic necks rising above the surrounding terrain. The field consists of lava domes, lava flow ...

Tuareg People
The Tuareg people (; also spelled Twareg or Touareg; endonym: ''Imuhaɣ/Imušaɣ/Imašeɣăn/Imajeɣăn'') are a large Berber ethnic group that principally inhabit the Sahara in a vast area stretching from far southwestern Libya to southern Algeria, Niger, Mali, and Burkina Faso. Traditionally nomadic pastoralists, small groups of Tuareg are also found in northern Nigeria. The Tuareg speak languages of the same name (also known as ''Tamasheq''), which belong to the Berber branch of the Afroasiatic family. The Tuaregs have been called the "blue people" for the indigo dye coloured clothes they traditionally wear and which stains their skin. They are a semi-nomadic people who practice Islam, and are descended from the indigenous Berber communities of Northern Africa, which have been described as a mosaic of local Northern African (Taforalt), Middle Eastern, European (Early European Farmers), and Sub-Saharan African-related ancestries, prior to the Arab expansion.
