Climate Of Qatar
Qatar is a peninsula in the east of Arabia, bordering the Persian Gulf and Saudi Arabia, in a strategic location near major petroleum deposits. The State of Qatar occupies on a peninsula that extends approximately to north into the Persian Gulf from the Arabian Peninsula. Varying in width between , the land is mainly flat (the highest point is ) and rocky. Notable features include coastal salt pans, elevated limestone formations (the Dukhan anticline) along the west coast under which lies the Dukhan oil field, and massive sand dunes surrounding Khawr al Udayd, an inlet of the Persian Gulf in the southeast known to local English speakers as the Inland Sea. General topography The peninsula of Qatar is low-lying. Its shape is the surface expression of the Qatar Arch, one of the largest structural characteristics of the Arabian Plate. It is enveloped by loose sand and pebbles broken off the outcropping limestone. Smooth plains are found in the east, where the surface is covered b ...

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Fuwayrit
Fuwayrit ( ar, فويرط; also spelled as Fuwairat) is a coastal village in Qatar, located in the municipality of Ash Shamal approximately 90 km north of the capital Doha. It is an important site for Qatar's oil industry. Archaeological evidence suggests that it may have been settled as early as the 16th century. Previously, it was one of the most important towns in the northern sector of Qatar, having served as the seat of power for the Al Thani who had migrated to it during the 18th century, prior to relocating to Al Bidda (presently Doha) in 1847. Etymology Fuwayrit is derived from the Arabic word 'farat' (or 'fart'), meaning to advance or to progress. This name was chosen in reference a man who left his tribe in Fuwayrit by boat. History 18th century According to family tradition, the Al Thani family migrated from Zubarah, previously Qatar's largest town, to Fuwayrit some time in the late 1700s. 19th century First British survey In the 1820s, George Barnes Brucks car ...

Bay Of Zekreet
The Bay of Zekreet ( ar, دَوْحَة زِكْرِيت, Dawḩat az Zikrīt) is a half-moon shaped bay on the Zekreet Peninsula in western Qatar. The Zekreet Peninsula is a rocky, sandy desert, with numerous rock formations and gypsum plateaux. The bay is situated to the north of the industrial city of Dukhan and to the southwest of the village of Zekreet. It is located to the north of the Dukhan Sabkha, and is separated by a straight depression known as Rawdat Jarrah. Geologists have theorized that this depression was an extension of the Bay of Zekreet prior to the drop in sea levels c. 3,000 years ago. Geology The area spanning from Dukhan to the upper part of the Bay of Zekreet is the only surface of Qatar where an entire section of the Eocene Dammam Formation is exposed. History A settlement dating to the early 19th century was discovered at the southern end of the bay, and was possibly presided over by the pirate ruler of Qatar, Rahmah ibn Jabir al-Jalahimah. Another ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dukhan Sabkha
Dukhan Sabkha, located in the northern section of the Dukhan region in western Qatar, is the largest inland sabkha (salt-flat) ecosystem found in the Persian Gulf. The sabkha runs for approximately 20 km, occupies an area of 73 km², has a width of 2 to 4 km and a depth of between 6 and 7 meters below sea level. Consequently, the sabkha holds the distinction of accommodating the lowest point of Qatar. It is situated roughly 10 km east of the city of Dukhan and 2 km from Dukhan Highway. The Dukhan Field is to its immediate west. Description Studies suggest that the sabkha is fed by seawater from the Bay of Zekreet, north by approximately 3 km. Geologists have theorized that Rawdat Jarrah, the depression separating Dukhan Sabkha from the Bay of Zekreet, was an extension of the bay prior to the drop in sea levels c. 3,000 years ago. Various species of algae are found on the sabkha surface. As a result of high uranium content, the sabkha has very high levels of radioactivity, r ...

Sawda Natheel
Sawda Natheel ( ar, سودا نثيل, Sawdā’ Nathīl) is an area in Qatar, located in the municipality of Al Rayyan. It used to be part of the Jariyan al Batnah municipality before the municipality was incorporated into Al Rayyan. It is a highly undeveloped area, consisting mainly of open desert. Of the 566.7 square km area of its zone, only 3 square km of land is under use. Farmland occupies 2 square km and cultural establishments account for the remaining 1 square km. The district itself only accounts for 49.6 km2 of the zone. Noteworthy features in the area are a border post separating the southern part of the municipality from Saudi Arabia, a well which the area was named after, and several farms. Etymology The area derived its name from the local well, which in turn had been named after dark precipitates found in its water. Sawda translates to 'black', while Natheel is an Arabic term used to denote soil deposits found in water obtained from a well. It is also known as ' ...

Mesaieed
Mesaieed ( ar, مسيعيد, also transliterated as ''Musay'id'' and ''Umm Sa'id'') is an industrial city in Al Wakrah Municipality in the State of Qatar, approximately south of Doha. It was one of the most important cities in Qatar during the 20th century, having gained in recognition as a prime industrial zone and tanking center for petroleum received from Dukhan. Both Mesaieed and its industrial area are administered by a subdivision of QatarEnergy called "Mesaieed Industry City Management", which was established in 1996. Etymology According to The Centre for Geographic Information Systems of Qatar, the city derives its name from a plant known locally as "sead" which previously grew in bountiful quantities in the area. History Mesaieed was established in 1949 as a tanker terminal by QatarEnergy on a previously uninhabited site along the coast. It was chosen by the company because of its proximity to the working population in Doha and Al Wakrah and because of the depth of it ...

Sabkha
A sabkha ( ar, سبخة) is a coastal, supratidal mudflat or sandflat in which evaporite-saline minerals accumulate as the result of semiarid to arid climate. Sabkhas are gradational between land and intertidal zone within restricted coastal plains just above normal high-tide level. Within a sabkha, evaporite-saline minerals sediments typically accumulate below the surface of mudflats or sandflats. Evaporite-saline minerals, tidal-flood, and aeolian deposits characterize many sabkhas found along modern coastlines. The accepted type locality for a sabkha is at the southern coast of the Persian Gulf, in the United Arab Emirates.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, eds.

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 ...

Coral Reefs
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of Colony (biology), colonies of coral polyp (zoology), polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the Class (biology), class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fis ...

Emergent Coastline
An emergent coastline is a stretch along the coast that has been exposed by the sea by a relative fall in sea levels by either isostasy or eustasy. Emergent coastline are the opposite of submergent coastlines, which have experienced a relative rise in sea levels. The emergent coastline may have several specific landforms: * Raised beach or machair * Wave cut platform * Sea cave such as King's Cave, Isle of Arran The Scottish Gaelic word ''machair'' or ''machar'' refers to a fertile low-lying raised beach found on some of the coastlines of Ireland and Scotland (especially the Outer Hebrides). Hudson Bay, in Canada's north, is an example of an emergent coastline. It is still emerging by as much as 1 cm per year. Another example of emergent coastline is the Eastern Coastal Plains of the Indian Subcontinent The Indian subcontinent is a list of the physiographic regions of the world, physiographical region in United Nations geoscheme for Asia#Southern Asia, Southern Asia.
