Tell Atlas
The Tell Atlas ( ar, الاطلس التلي, Latn, ar, al-ʾaṭlas al-tlī) is a mountain chain over in length, belonging to the Atlas mountain ranges in North Africa, stretching mainly across northern Algeria, with ends in both north-eastern Morocco and north-western Tunisia. The ranges of this system have an average elevations of about and form a natural barrier between the Mediterranean and the Sahara. Its highest summit is the high Lalla Khedidja in the Jurjura Range. Several large cities such as the Algerian capital, Algiers, with ~1,500,000 residents (2005) and Oran with ~770,000 residents (2005) lie at the base of the Tell Atlas. The Algerian city Constantine with approximately 505,000 residents (2005) lies 80 km inland and directly in the mountains at 650 meters in elevation. A number of smaller towns and villages are situated within the Tell; for example, Chiffa is nestled within the Chiffa gorge. Geography The Tell Atlas runs parallel to the Mediterranean c ...

Abies Numidica
''Abies numidica'', the Algerian fir, is a species of fir found only in Algeria, where it is endemic on Djebel Babor, the second-highest mountain (2,004 meters) in the Algerian Tell Atlas.Farjon, A.

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean Climate
A Mediterranean climate (also called a dry summer temperate climate ''Cs'') is a temperate climate sub-type, generally characterized by warm, dry summers and mild, fairly wet winters; these weather conditions are typically experienced in the majority of Mediterranean-climate regions and countries, but remain highly dependent on proximity to the ocean, altitude and geographical location. This climate type's name is in reference to the coastal regions of the Mediterranean Sea within the Mediterranean Basin, where this climate type is most prevalent. The "original" Mediterranean zone is a massive area, its western region beginning with the Iberian Peninsula in southwestern Europe and coastal regions of northern Morocco, extending eastwards across southern Europe, the Balkans, and coastal Northern Africa, before reaching a dead-end at the Levant region's coastline. Mediterranean climate zones are typically located along the western coasts of landmasses, between roughly 30 and 45 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seybouse River
Seybouse (in arq, rtl=yes, وادي سيبوس, Oued Seybouse) is a river in northeastern Algeria, near the border with Tunisia. In Roman times, it was called the ''Ubus''.

Salt Pan (geology)
Natural salt pans or salt flats are flat expanses of ground covered with salt and other minerals, usually shining white under the sun. They are found in deserts and are natural formations (unlike salt evaporation ponds, which are artificial). A salt pan forms by evaporation of a water pool, such as a lake or pond. This happens in climates where the rate of water evaporation exceeds the rate of that is, in a desert. If the water cannot drain into the ground, it remains on the surface until it evaporates, leaving behind minerals precipitated from the salt ions dissolved in the water. Over thousands of years, the minerals (usually salts) accumulate on the surface. These minerals reflect the sun's rays (through radiation) and often appear as white areas. Salt pans can be dangerous. The crust of salt can conceal a quagmire of mud that can engulf a truck. The Qattara Depression in the eastern Sahara Desert contains many such traps which served as strategic barriers during World ...

Hautes Plaines
The Hautes Plaines ("High Plains", ar, الهضاب العليا), also known as Hauts Plateaux, is a steppe-like natural region located in the Atlas Mountains in northern Algeria. It stretches more than in an east northeast – west southwest direction from northeastern Morocco to the Aures. It is a high plateau area consisting of undulating, steppe-like alluvial plains lying between the Tell and Saharan Atlas ranges. Geography The ''Hautes Plaines'' region averages between 1,100 and 1,300 m in elevation in the west, dropping to 400 m in the east. The climate is characterized by very dry summers and cold winters. Generally the climate is so dry that these plains are sometimes thought of as part of the Sahara. The plateau area is covered by alluvial debris formed when the mountains eroded. An occasional ridge projects through the alluvial cover to interrupt the monotony of the landscape. Water collects during the wet season on its level terrain, forming large shallow salt ...

Physiographic
Physical geography (also known as physiography) is one of the three main branches of geography. Physical geography is the branch of natural science which deals with the processes and patterns in the natural environment such as the atmosphere, hydrosphere, biosphere, and geosphere. This focus is in contrast with the branch of human geography, which focuses on the built environment, and technical geography, which focuses on using, studying, and creating tools to obtain,analyze, interpret, and understand spatial information. The three branches have significant overlap, however. Sub-branches Physical geography can be divided into several branches or related fields, as follows: * Geomorphology is concerned with understanding the surface of the Earth and the processes by which it is shaped, both at the present as well as in the past. Geomorphology as a field has several sub-fields that deal with the specific landforms of various environments e.g. desert geomorphology and fluvial ...
