Lake Assal (Djibouti)
Lake Assal ( ar, بحيرة عسل , lit. “Honey Lake”) is a crater lake in central-western Djibouti. It is located at the western end of Gulf of Tadjoura between Arta Region, and Tadjoura Region, touching Dikhil Region, at the top of the Great Rift Valley, some west of Djibouti city. Lake Assal is a saline lake that lies below sea level in the Afar Triangle, making it the lowest point on land in Africa and the third-lowest point on Earth after the Sea of Galilee and the Dead Sea. No outflow occurs from the lake, and due to high evaporation, the salinity level of its waters is 10 times that of the sea, making it the third most saline body of water in the world behind Don Juan Pond and Gaet'ale Pond. The salt in the lake is exploited under four concessions awarded in 2002 at the southeast end of the lake; the major share of production (nearly 80%) is held by Société d’Exploitation du Lac and Société d’Exploitation du Salt Investment S.A de Djibouti. The lake is a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Tadjoura
The Gulf of Tadjoura (; ) is a gulf or basin of the Indian Ocean in the Horn of Africa. It lies south of the straits of Bab-el-Mandeb, or the entrance to the Red Sea, at . The gulf has many fishing grounds, extensive coral reefs, and abundant pearl oysters. Most of its coastline is the territory of Djibouti, except for a short stretch on the southern shore, which is part of the territory of Somaliland. The Gulf’s other marine habitats include sea grass beds, salt pans and mangroves. History In August 1840, the conclusion of a treaty of friendship and commerce between the Sultan Mohammed bin Mohammed of Tadjoura and Commander Robert Moresby of the Indian Navy is tracking the sale of Moucha Island to Great Britain for ten sacks of rice. The sale will however follow any occupation. In 1887, Britain cedes sovereignty of the island to France at the same time it recognizes the French sphere of influence in the Gulf of Tadjoura, in exchange for the abandonment by France of any right ...

Ardoukoba
Ardoukôba ( ar, أردوكوبا) is a fissure vents volcano in Djibouti. Located on the coast from Djibouti City, its summit is situated at above sea level. It last erupted in November 1978 following an earthquake, the area having been dormant for 3,000 years. The volcano's rift is in width, and has a depth of . The Government of Djibouti has initiated a proposal with UNESCO to declare the Lake Assal zone including the Ardoukoba volcano and its surroundings as a World Heritage Site. Geography Culminating at an altitude of 298 meters, the Ardoukôba is a volcano born from a volcanic fissure and composed of a pile of basaltic slag forming three cones emitting two flows of fluid basaltic lava. These eruptive characteristics classify the Ardoukôba among the red volcanoes fed by a rift magma. This northwest-southeast trending volcanic fissure is part of the Great Rift Valley fault system between the Danakil block in the northeast and the Afar depression in the southwest. Hist ...

Cove
A cove is a small type of bay or coastal inlet. Coves usually have narrow, restricted entrances, are often circular or oval, and are often situated within a larger bay. Small, narrow, sheltered bays, inlets, creeks, or recesses in a coast are often considered coves. Colloquially, the term can be used to describe a sheltered bay. Geomorphology describes coves as precipitously-walled and rounded cirque-like openings as in a valley extending into or down a mountainside, or in a hollow or nook of a cliff or steep mountainside. A cove can also refer to a corner, nook, or cranny, either in a river, road, or wall, especially where the wall meets the floor. A notable example is Lulworth Cove on the Jurassic Coast in Dorset, England. To its west, a second cove, Stair Hole, is forming. Formation Coves are formed by differential erosion Weathering is the deterioration of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gase ...

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 (topography), 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 Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, 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 Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

Cliff
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also fea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Shark
Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays. However, the term "shark" has also been used to refer to all extinct members of Chondrichthyes with a shark-like morphology, such as hybodonts and xenacanths. The oldest modern sharks are known from the Early Jurassic. They range in size from the small dwarf lanternshark (''Etmopterus perryi''), a deep sea species that is only in length, to the whale shark (''Rhincodon typus''), the largest fish in the world, which reaches approximately in length. Sharks are found in all seas and are common to depths up to . They generally do not live in freshwater, although there are a few known exceptions, such as the bull shark and the river shark, which can be found in both seawater and fresh ...

Continental Plates
Plate tectonics (from the la, label=Late Latin, tectonicus, from the grc, τεκτονικός, lit=pertaining to building) is the generally accepted scientific theory that considers the Earth's lithosphere to comprise a number of large tectonic plates which have been slowly moving since about 3.4 billion years ago. The model builds on the concept of ''continental drift'', an idea developed during the first decades of the 20th century. Plate tectonics came to be generally accepted by geoscientists after seafloor spreading was validated in the mid to late 1960s. Earth's lithosphere, which is the rigid outermost shell of the planet (the crust and upper mantle), is broken into seven or eight major plates (depending on how they are defined) and many minor plates or "platelets". Where the plates meet, their relative motion determines the type of plate boundary: '' convergent'', '' divergent'', or ''transform''.

Jacques Cousteau
Jacques-Yves Cousteau, (, also , ; 11 June 191025 June 1997) was a French naval officer, oceanographer, filmmaker and author. He co-invented the first successful Aqua-Lung, open-circuit SCUBA (self-contained underwater breathing apparatus). The apparatus assisted him in producing some of the first underwater documentaries. Cousteau wrote many books describing his undersea explorations. In his first book, '' The Silent World: A Story of Undersea Discovery and Adventure'', Cousteau surmised the existence of the echolocation abilities of porpoises. The book was adapted into an underwater documentary called ''The Silent World''. Co-directed by Cousteau and Louis Malle, it was one of the first films to use underwater cinematography to document the ocean depths in color. The film won the 1956 Palme d'Or at the Cannes Film Festival and remained the only documentary to do so until 2004, when '' Fahrenheit 9/11'' received the award. It was also awarded the Academy Award for Best Do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
