Ribiana Sand Sea
The Rabyanah Sand Sea, Rabyanah, is a sand desert region spanning approximately 65,000 km2 in southeastern Libya. Geography The area of the Rabyanah Sand Sea is in the western part of the Libyan Desert in the Kufra District of the Cyrenaica region. It is named after the oasis town of Rabyanah located towards its eastern end. Together with the Calanshio Sand Sea and the Great Sand Sea, the Rabyanah Sand Sea is part of the greater Libyan Desert.Besler, Helga (2008).

Desert
A desert is a landscape where little precipitation occurs and, consequently, living conditions create unique biomes and ecosystems. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or Semi-arid climate, semi-arid. This includes much of the Polar regions of Earth, polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night strain the Rock (geology), rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting frag ...

Phoenix Dactylifera
''Phoenix dactylifera'', commonly known as the date palm, is a flowering-plant species in the palm family Arecaceae, cultivated for its edible sweet #Fruits, fruit called dates. The species is widely cultivated across North Africa, northern Africa, the Middle East, the Horn of Africa, Australia, South Asia, and the desert regions of Southern California in the United States. It is Naturalisation (biology), naturalized in many Tropics, tropical and Subtropics, subtropical regions worldwide. ''P. dactylifera'' is the type species of genus ''Phoenix (plant), Phoenix'', which contains 12–19 species of wild date palms. Date palms reach up to 60–110 feet in height, growing singly or forming a Clumping (biology), clump with several stems from a single root system. Slow-growing, they can reach over 100years of age when maintained properly. Date fruits (dates) are oval-cylindrical, long, and about in diameter, with colour ranging from dark brown to bright red or yellow, depen ...

Libyan Desert
The Libyan Desert (not to be confused with the Libyan Sahara) is a geographical region filling the northeastern Sahara Desert, from eastern Libya to the Western Desert (Egypt), Western Desert of Egypt and far northwestern Sudan. On medieval maps, its use predates today's Sahara, and parts of the Libyan Desert include the Sahara's most arid and least populated regions; this is chiefly what sets the Libyan Desert apart from the greater Sahara. The consequent absence of grazing, and near absence of waterholes or wells needed to sustain camel caravans, prevented Trans-Saharan trade between Kharga (the Darb al Arbein) close to the Nile, and Murzuk in the Libyan Fezzan. This obscurity saw the region overlooked by early European explorers, and it was not until the early 20th century and the advent of the motor car before the Libyan Desert started to be fully explored. Nomenclature The term ''Libyan Desert'' began to appear widely on European maps in the last decades of the 19th centu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sahara
The Sahara (, ) is a desert spanning across North Africa. With an area of , it is the largest hot desert in the world and the list of deserts by area, third-largest desert overall, smaller only than the deserts of Antarctica and the northern Arctic. The name "Sahara" is derived from , a broken plural form of ( ), meaning "desert". The desert covers much of North Africa, excluding the fertile region on the Mediterranean Sea coast, the Atlas Mountains of the Maghreb, and the Nile, Nile Valley in Egypt and the Sudan. It stretches from the Red Sea in the east and the Mediterranean in the north to the Atlantic Ocean in the west, where the landscape gradually changes from desert to coastal plains. To the south it is bounded by the Sahel, a belt of Tropical and subtropical grasslands, savannas, and shrublands, semi-arid tropical savanna around the Niger River valley and the Sudan (region), Sudan region of sub-Saharan Africa. The Sahara can be divided into several regions, including ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erg (landform)
An erg (also sand sea or dune sea, or sand sheet if it lacks dunes) is a broad, flat area of desert covered with wind-swept sand with little or no vegetative cover. The word is derived from the Arabic language, Arabic word ''ʿirq'' (), meaning "dune field". Strictly speaking, an erg is defined as a desert area that contains more than of aeolian processes, aeolian or wind-blown sand and where sand covers more than 20% of the surface. Smaller areas are known as "dune fields". The largest hot desert in the world, the Sahara, covers and contains several ergs, such as the Chech Erg and the Issaouane Erg in Algeria. Approximately 85% of all the Earth's mobile sand is found in ergs that are greater than , the largest being the Rub' al Khali, the ''Empty Quarter'' of the Arabian Peninsula. Ergs are also found on other celestial bodies, such as Venus, Mars, and Saturn's moon Titan (moon), Titan. Geography Sand seas and dune fields generally occur in regions downwind of copious sourc ...

Kufra District
Kufra, Kufrah or Kofra ( '), also spelled ''Cufra'' in Italian, is the largest district of Libya and the second largest such district in Africa. It is slightly smaller than the country of Turkmenistan. Its capital is Al Jawf, one of the oases in Kufra basin. There is a very large oil refinery near the capital. In the late 15th century, Leo Africanus reported an oasis in the land of the ''Berdoa'', visited by a caravan coming from Awjila. It is possible that this oasis in question was either the Al Jawf or the Taiserbo oasis, and on early modern maps, the Al Kufra region was often labelled as ''Berdoa'' based on this report. History The name ''Kufra'' (comes from Kufuh and Epher) itself is a derivation from ''kafir'', the Arabic term for disbeliever. Kufra did not fall under the dominion of either the Arabs or the Ottomans and was owned by the Arab Bedouin tribe of the Zuwayya only in the mid-19th century, and eventually by the Italians by the 1930s. In 1931, during the campaig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyrenaica
Cyrenaica ( ) or Kyrenaika (, , after the city of Cyrene), is the eastern region of Libya. Cyrenaica includes all of the eastern part of Libya between the 16th and 25th meridians east, including the Kufra District. The coastal region, also known as ''Pentapolis'' ("Five Cities") in antiquity, was part of the Roman province of Crete and Cyrenaica, later divided into ''Libya Pentapolis'' and ''Libya Sicca''. During the Islamic period, the area came to be known as ''Barqa'', after the city of Barca. Cyrenaica became an Italian colony in 1911. After the 1934 formation of Italian Libya, the Cyrenaica province was designated as one of the three primary provinces of the country. During World War II, it fell under British military and civil administration from 1943 until 1951, and finally in the Kingdom of Libya from 1951 until 1963. The region that used to be Cyrenaica officially until 1963 has formed several shabiyat, the administrative divisions of Libya, since 1995. ...

Great Sand Sea
The Great Sand Sea is an approximately sand desert (erg) in the Sahara that stretches from western Egypt to eastern Libya, in North Africa. Most of the area is covered by sand dunes. Geography The Great Sand Sea stretches about from north to south and from east to west. On satellite images, this desert shows a pattern of long sand ridges running in a roughly north-south direction. However, despite the apparent uniformity, the Great Sand Sea has two large areas with different types of megadunes.Besler, Helga (2008) ''The Great Sand Sea in Egypt: Formation, Dynamics and Environmental Change: A Sediment-Analytical Approach'' Elsevier, Amsterdampage 1 - 3 The Egyptian sand sea lies parallel to the Calanshio Sand Sea of Libya, with which it is contiguous in the north.
