Rocher De Sel
Rocher de Sel ("Salt Rock"), known in Arabic as Khanguet-el-Melah ("Parade of Salt"), is a large geological formation in the Ouled Naïl Range, near the town of Djelfa. Rocher de Sel is composed of a mixture of salt and clay Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4). Clays develop plasticity when wet, due to a molecular film of water surrounding the clay par ..., and is nearly in diameter and tall. Due to its composition, Rocher de Sel is distinctly whitish-gray, and entirely barren of plant life. Rocher de Sel was formed when the earth's crust folded upwards, pushing a previously-buried layer of salt and clay upwards in a bulge. Later precipitation would erode the surface into its current scarred and furrowed state. It is unknown why the formation has not eroded completely, despite the susceptibility of its materials. It has been suggested that the clay repels the area ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Arabic
Arabic (, ' ; , ' or ) is a Semitic languages, Semitic language spoken primarily across the Arab world.Semitic languages: an international handbook / edited by Stefan Weninger; in collaboration with Geoffrey Khan, Michael P. Streck, Janet C. E.Watson; Walter de Gruyter GmbH & Co. KG, Berlin/Boston, 2011. Having emerged in the 1st century, it is named after the Arabs, Arab people; the term "Arab" was initially used to describe those living in the Arabian Peninsula, as perceived by geographers from ancient Greece. Since the 7th century, Arabic has been characterized by diglossia, with an opposition between a standard Prestige (sociolinguistics), prestige language—i.e., Literary Arabic: Modern Standard Arabic (MSA) or Classical Arabic—and diverse vernacular varieties, which serve as First language, mother tongues. Colloquial dialects vary significantly from MSA, impeding mutual intelligibility. MSA is only acquired through formal education and is not spoken natively. It is ...

Ouled Naïl Range
The Ouled Naïl Range ( ar, سلسلة جبال أولاد نايل, french: Monts des Ouled Naïl) is a mountain range in Algeria, part of the Saharan Atlas of the greater Atlas Mountain System. The range is named after a confederation of nomadic and semi-nomadic tribes, all of which claim to hail from Berber ancestors whose origin are lost to history. Geography The Ouled Naïl mountain range is formed by parallel ridges rising between the level 850 m high terrain of the Hodna region of the ''Hautes Plaines'' in the north and the 600 m of the southern plain of the ''Dayas''. It is located in the eastern zone of the Saharan Atlas, with the Amour Range in the western and the Zab Range at the eastern end. The range is formed by mountains created by folds of the early Tertiary which remained relatively undisturbed after formation but have been heavily eroded. Their altitude is relatively moderate, the highest point of the range, Djebel Lazrag (جبل الأزرق), not even reac ...

Djelfa
Djelfa ( ar, الجلفة, link=no, al-Ǧilfah) is the capital city of Djelfa Province, Algeria and the site of ancient city and former bishopric Fallaba, which remains a Latin catholic titular see. It has a population of 490,248 (2018 census). The city lies at the junction of the N1 and the N46 roads. Geography Djelfa is located at an elevation of 3,734 feet (1,138 m) in the Ouled Naïl Range of north-central Algeria, between the towns of Bousaada and Laghouat. It is situated in a transitional zone between the dry, steppe-like Hautes Plaines (high plateaus) of the north, characterized by chotts (intermittent salt lakes), and the Sahara to the south. The town was founded in 1852 as a French military post on a geometric plan. It serves as an important livestock market centre for the semi-nomadic Ouled Naïl confederation. Djelfa is on the 12,000 mile-long Africa Trail. The surrounding region for centuries has been the meeting place of the Ouled Naïl people, who live in black ...

Salt
Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in the form of a natural crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater. The open ocean has about of solids per liter of sea water, a salinity of 3.5%. Salt is essential for life in general, and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and is known to uniformly improve the taste perception of food, including otherwise unpalatable food. Salting, brining, and pickling are also ancient and important methods of food preservation. Some of the earliest evidence of salt processing dates to around 6,000 BC, when people living in the area of present-day Romania boiled spring water to extract salts; a salt-works in China dates to approximately the same period. Salt was also prized by the ancient Hebrews, Greeks, Romans, Byzantines, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4). Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clay is the oldest known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been dated to around 14,000 BC, and clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often ...

Landforms Of Algeria
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
