The United Arab Emirates is situated in Middle East/southwest Asia, bordering the Gulf of Oman and the Persian Gulf, between Oman and Saudi Arabia; it is on a strategic location along northern approaches to the Strait of Hormuz, a vital transit point for world crude oil.
 The UAE lies between 22°50′ and 26° north latitude and between 51° and 56°25′ east longitude.
 It shares a 19-kilometer border with Qatar on the northwest, a 530-kilometer border with Saudi Arabia on the west, south, and southeast, and a 450-kilometer border with Oman on the southeast and northeast.
 The land border with Qatar in the Khawr al Udayd area is a source of ongoing dispute (in fact, whether it even shares a land border with Qatar is in dispute).
 The total area of the UAE is approximately 83,600 square kilometers.
 The country's exact size is unknown because of disputed claims to several islands in the Persian Gulf, because of the lack of precise information on the size of many of these islands, and because most of its land boundaries, especially with Saudi Arabia, remain undemarcated.
 The largest emirate, Abu Dhabi, accounts for 87 percent of the UAE's total area (72,732 square kilometers).
 The smallest emirate, Ajman, encompasses only 259 square kilometers.
Chelemys delfini, also known as the Magellanic long-clawed akodont, is a species of rodent in the genus "Chelemys" of family Cricetidae.
 It is endemic to the areas of Punta Arenas and Torres del Paine National Park in southern Chile, where it lives in the grassland and scrub of the Magellanic steppe.
Awash National Park is one of the national parks of Ethiopia.
 Spanning across the southern tip of the Afar Region and the northeastern corner of the Misraq Shewa Zone of Oromia, this park is 225 kilometers east of Addis Ababa (and a few kilometers west of Awash), with its southern boundary along the Awash River, and covers 756 square kilometers of acacia woodland and grassland.
 The Addis Ababa - Dire Dawa highway passes through this park, separating the Illala Saha Plains to the south from the Kudu Valley to the north.
 In the south of the park the Awash River gorge has amazing waterfalls.
 In the upper Kudu Valley at Filwoha are hot springs amid groves of palm trees.
Marj Sanur (Arabic: مرج صانور‎ ‎ , translation: "Sanur Valley"; also called Marj al-Ghuruq, translation: "Drowning Valley") is a closed basin within the northern mountains of the West Bank, located entirely in the southern Jenin Governorate, in between the cities of Jenin (to the north) and Nablus (to the south).
 Its total area is roughly 20 square kilometers, while its drainage basin is about 55 square kilometers, most of which is in the Jenin Governorate, with two square kilometers extending into the Tubas Governorate.
 Marj Sanur abuts the Qabatiya Mountains to the north, the Zawiya Hills to the west and the Musheirif Highlands to the south.
 Further to the northwest is the Sahl Arraba valley and further to the east, past the towns of Aqqaba and Tubas, is the Jordan Valley.
Kellia ("the Cells"), referred to as "the innermost desert", was a 4th-century Egyptian Christian monastic community spread out over many square kilometers in the Nitrian Desert.
 It was one of three centers of monastic activity in the region, along with Nitria and Scetis (Wadi El Natrun).
 It is called al-Muna in Arabic and was inhabited until the 9th century.
 Only archaeological sites remain there today.
The Patagonian Desert, also known as the Patagonia Desert, Patagonian Steppe, or Magellanic Steppe, is the largest desert in Argentina and is the 8th largest desert in the world by area, occupying 673,000 square kilometers (260,000 mi).
 It is located primarily in Argentina with small parts in Chile and is bounded by the Andes, to its west, and the Atlantic Ocean to its east, in the region of Patagonia, southern Argentina.
 To the north the desert grades into the Cuyo Region and the Pampas.
 The central parts of the steppe are dominated by shrubby and herbaceous plant species albeit to the west, where precipitation is higher, bushes are replaced by grasses.
 Topographically the deserts consist of alternating tablelands and massifs dissected by river valleys and canyons.
 The more western parts of the steppe host lakes of glacial origin and grades into barren mountains or cold temperate forests along valleys.
Chelemys is a genus of South American rodents in the tribe Abrotrichini of family Cricetidae.
 Three species—"Chelemys delfini", "Chelemys macronyx", and "Chelemys megalonyx"—are known, all found in central and southern Chile and Argentina.
The Comoros archipelago consists of four main islands aligned along a northwest-southeast axis at the north end of the Mozambique Channel, between Mozambique and the island of Madagascar.
 Still widely known by their French names, the islands officially have been called by their Swahili names by the Comorian government.
 They are Grande Comore (Njazidja), Mohéli (Mwali), Anjouan (Nzwani), and Mayotte (Mahoré).
 The islands' distance from each other—Grande Comore is some 200 kilometers from Mayotte, forty kilometers from Mohéli, and eighty kilometers from Grande Comore—along with a lack of good harbor facilities, make transportation and communication difficult.
 The islands have a total land area of 2,236 square kilometers (including Mayotte), and claim territorial waters of 320 square kilometers.
 Mount Karthala (2316 m) on Grande Comore is an active volcano.
 From April 17 to 19, 2005, the volcano began spewing ash and gas, forcing as many as 10,000 people to flee.
The Ordos Desert, also known as the Muu-us (bad water) Desert, () is a desert and steppe region lying on a plateau in the south of the Inner Mongolian Autonomous Region of the People's Republic of China (centered ca. )
.
 The soil of the Ordos is a mixture of clay and sand and, as a result, is poorly suited for agriculture.
 It extends over an area of approximately 90,650 km².
 It comprises two large deserts: the 7th largest desert in China, the Kubuqi Desert (库布其沙漠 /庫布齊沙漠; "pinyin": KùbùqíShāmò ) in the north, and the 8th largest desert in China, the Muu-us Desert (毛乌素沙漠 /毛烏素沙漠; "pinyin": MáowūsùShāmò ), in the south.
A microclimate is a local set of atmospheric conditions that differ from those in the surrounding areas, often with a slight difference but sometimes with a substantial one.
 The term may refer to areas as small as a few square meters or square feet (for example a garden bed or a cave) or as large as many square kilometers or square miles.
 Because climate is statistical, which implies spatial and temporal variation of the mean values of the describing parameters, within a region there can occur and persist over time sets of statistically distinct conditions, that is, microclimates.
 Microclimates can be found in most places.
