Dallol, Ethiopia
Dallol ( am, ዳሎል) is a locality in the Dallol woreda of northern Ethiopia. Located in Kilbet Rasu, Afar Region in the Afar Depression, it has a latitude and longitude of with an elevation of about below sea level. The Central Statistical Agency has not published an estimate for the 2005 population of the village, which has been described as a ghost town. Dallol currently holds the official record for record high average temperature for an inhabited location on Earth, and an average annual temperature of 35 °C (95 °F) was recorded between 1960 and 1966. Dallol is also one of the most remote places on Earth, but paved roads to the nearby village of Hamedela are being built. Still, the most important mode of transport besides jeeps are the camel caravans that travel to the area to collect salt. In the region is the highly active hydrothermal system of Dallol, with numerous springs, terrace systems and fumaroles. History A railway from the port of Mersa Fatma in ...

Danakil Depression
The Danakil Depression is the northern part of the Afar Triangle or Afar Depression in Ethiopia, a geological depression that has resulted from the divergence of three tectonic plates in the Horn of Africa. Geology The Danakil Depression lies at the triple junction of three tectonic plates and has a complex geological history. It has developed as a result of Africa and Asia moving apart, causing rifting and volcanic activity. Erosion, inundation by the sea, the rising and falling of the ground have all played their part in the formation of this depression. Sedimentary rocks such as sandstone and limestone are unconformably overlain by basalt which resulted from extensive lava flows. IUGS geological heritage site In respect of it demonstrating 'the ongoing birth of an ocean witnessed through tectonics and volcanism in an extreme evaporite arid environment', the International Union of Geological Sciences (IUGS) included 'The Danakil Rift depression and its volcanism' in its asse ...

Danakil Desert
The Danakil Desert is a desert in northeast Ethiopia, southern Eritrea, and northwestern Djibouti. Situated in the Afar Triangle, it stretches across of arid terrain. It is inhabited by a few Afar, who engage in salt mining. The area is known for its volcanoes and extreme heat, with daytime temperatures surpassing . Less than of rainfall occurs each year. The Danakil Desert is one of the lowest and hottest places on Earth. Climate Dallol (92 metres below sea level), has the hottest average temperature recorded on earth: Geology Local geology is characterized by volcanic and tectonic activity, various climate cycles, and discontinuous erosion. The basic geological structure of this area was caused by the movement of tectonic plates as Africa moved away from Asia. Mountain chains formed and were eroded again during the Paleozoic. Inundations by the sea caused the formation of layers of sandstone, and limestone was deposited further offshore. As the land rose again, furt ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hot Desert Climate
The desert climate or arid climate (in the Köppen climate classification ''BWh'' and ''BWk''), is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive. Covering 14.2% of earth's land area, hot deserts are the second most common type of climate on earth after the polar climate. There are two variations of a desert climate according to the Köppen climate classification: a hot desert climate (''BWh''), and a cold desert climate (''BWk''). To delineate "hot desert climates" from "cold desert climates", there are three widely used isotherms: most commonly a mean annual temperature of , or sometimes the coldest month's mean temperature of , so that a location with a ''BW'' type climate with the appropriate temperature above whichever isotherm is being used is classified as "hot arid subt ...

Going To Extremes
''Going to Extremes'' and ''Surviving Extremes'' were television programmes made for Channel 4 by Nick Middleton. In each episode of the two series, Middleton visited an extreme area of the world to find out how people have adapted to life there. Both ''Going to Extremes'' and ''Surviving Extremes'' were accompanied by books of the same name, except in the USA where the latter was titled ''Extremes: Surviving the World's Harshest Environments''. There was also a third series, titled ''Going to Extremes: The Silk Routes''. ''Going to Extremes'' In this series, Middleton visited the coldest, hottest, driest and wettest permanent settlements in the world. ;Coldest: Oymyakon in Siberia, where the average winter temperature is −47 °F (− 44 °C). ;Driest: Arica in Chile, where there had been fourteen consecutive years without rain. Fog is the only local source of water. ;Wettest: Mawsynram in India, where average annual rainfall is 14 meters, falling within a fou ...

Geological Survey
A geological survey is the systematic investigation of the geology beneath a given piece of ground for the purpose of creating a geological map or model. Geological surveying employs techniques from the traditional walk-over survey, studying outcrops and landforms, to intrusive methods, such as hand augering and machine-driven boreholes, to the use of geophysical techniques and remote sensing methods, such as aerial photography and satellite imagery. Such surveys may be undertaken by state, province, or national geological survey organizations to maintain the geological inventory and advance the knowledge of geosciences for the benefit of the nation. A geological survey map typically superimposes the surveyed extent and boundaries of geological units on a topographic map, together with information at points (such as measurements of orientation of bedding planes) and lines (such as the intersection of faults with the land surface). The maps and reports created by geological surv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, By ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asmara
Asmara ( ), or Asmera, is the capital and most populous city of Eritrea, in the country's Central Region. It sits at an elevation of , making it the sixth highest capital in the world by altitude and the second highest capital in Africa. The city is located at the tip of an escarpment that is both the northwestern edge of the Eritrean Highlands and the Great Rift Valley in neighbouring Ethiopia. In 2017, the city was declared as a UNESCO World Heritage Site for its well-preserved modernist architecture. The site of Asmera was first settled in 800 BC with a population ranging from 100 to 1,000. The city was then founded in the 12th century AD after four separate villages unified to live together peacefully after long periods of conflict. Under Italian rule the city of Asmara was made capital of Eritrea in the last years of the 19th century.
