Desert

MOST AMAZING DESERT PEACE Sahara - the largest and hottest desert on the planet Sahara ("The greatest desert") is the largest hot desert of the world, an area of ??more than 9,000,000 sq km (3,500,000 sq mi) and she takes most of North Africa (Algeria, Chad, Morocco, Libya, Egypt, Mali, Niger, Mauritania, Sudan, Tunisia and Western Sahara). On the west by the Atlantic Ocean Sahara and to the east - the Red Sea, in the north it is bordered by the Atlas Mountains and the Mediterranean Sea. About 15% of the desert are sand dunes, 70% are stony plains, and the remainder is composed of limestone and shale plateau. Sahara - the largest and hottest desert in the world have the greatest desert subtropical climate in the northern and tropical - in the south. Winter in the north is cool enough in the south - in moderation. Summer is hot throughout the desert. The highest temperature, which was fixed for all time of observations, is 57.7 degrees Celsius or 135.9 Fahrenheit. Record belongs to the Libyan city of Azizia. This figure is also the highest on record temperatures on the Earth's surface. According to archaeologists, before the Sahara was inhabited by a much denser. It was more than twenty thousand years ago, when the desert climate was not so arid as today. Once this area was a paradise, lush, but the climate gradually became drier and drier, and the fertile landscape into a barren area that we see today. Nevertheless, some studies and surveys show that the desert is not formed without human intervention, because of its agricultural and irrigation activities. For centuries, traveled through the Sahara desert caravan. And, although many of the oases in the Sahara, the desert is so vast that travelers might need more than one day to reach them. Atacama - the driest desert in the world the Atacama Desert - the driest desert of the Earth, is 1000 km (600 miles) north of Chile, located between the Pacific Ocean and the Andes, stretching to the border with Peru. The average annual rainfall in the desert is about 25 mm (1 inch), and in some places deep in the desert the rain does not fall out ever. The range of average temperatures ranging from zero to 25 degrees Celsius, or from 32 to 75 Fahrenheit. Atacama - the driest desert in the world This desert is located in South America between the Andes and the Pacific Ocean, northern Chile. Most of the precipitation in the Atacama is in the form of fog (in a certain place, such as Komanchake) brought in by wind from the Pacific Ocean. Mist nourishes plant community called a crowbar. They are separate islands of vegetation that may include many species of cactus to ferns. The reason that the Atacama is not getting enough rain, lies in a phenomenon called rain shadow area. Warm, moist tropical air that brings the east trade winds, flood the rainforest of South America, has been delayed in the eastern part of the Andes and reaches the territory of the desert. The Gobi Desert The Gobi Desert - the largest desert in Asia, are also involved in part of southern Mongolia and northwestern China. The desert stretches over 1600 km (900 miles) south-west to north-east and 800 km (500 miles) from north to south, it lies at an altitude of 1,520 m above sea level. The climate of the Gobi Desert extremely diverse due to its long-haul and drop heights above sea level, extreme temperature variations in nature: in some desert areas in summer maximum temperature in July is 45 degrees Celsius (113 Fahrenheit) and minimum in winter, in January , reaches -40 Celsius (-40 Fahrenheit). The Gobi Desert in contrast to an idealized view of the desert stretching to the horizon, with sand dunes, much of the landscape of the Gobi is a stony, dense terrain. Despite the fact that the solid earth underfoot facilitate the crossing of the desert, thereby giving the Gobi, the status of a viable trade route to the stage of history, until now there were almost no permanent human activity. Despite the extreme and very harsh climatic conditions and the Gobi desert is one of the most attractive places in the world for paleontologists, the leading search of dinosaur fossils. Salar de Yuni - the world's largest solonchak desert desert Salar de Yuni (or Salar de Tunupa), the size of 10,582 square kilometers (4,085 square miles), is the largest saline desert in the world. It is located in the district of Potosi in southwest Bolivia, near the ridge of the Andes. Estimated reserves of salt in the Salar de Yuni is 10 billion tons. Salar de Yuni - the world's largest desert solonchak About 40 000 years ago this area was part of a giant lake of Lago Minchin. After the lake dried up, it was under two modern lakes, Lagos Uru Uru and Pupo, and two major brackish deserts Koipassa and bigger Uni. Despite the dryness of the scorching sun, here the case of negative (Celsius) night temperatures and the landscape is not devoid of life. In the Salar de Yuni live pink flamingos, ancient and rare species of cacti hummingbirds. Death Valley Death Valley Desert, is one of the hottest places on Earth's surface, it is located in California, USA. 10 July 1913 the temperature in the Valley rose to 56 degrees Celsius (134 Fahrenheit) and annual (potential) evaporation is the highest in the world and is 325 centimeters (128 inches). In addition, the desert is the driest place in North America: the average annual rainfall is less than 5 centimeters (2 inches) per year. Death Valley is one of the most interesting places on earth for geologists, and in terms of diversity of minerals, and in terms of configuration of sediment rocks. There are salt and alkali deposits, unique rock formations and salt ponds. Death Valley, California, USA Valley got its English name in 1849 during the Gold Rush in California. Death valley nicknamed her gold miners and all those who tried to cross it, making his way to the gold fields. I must say that the miners are greatly exaggerated, choosing a name for this valley, for in those days there was killed just one person. In the 50 years of the XIX century. in the valley of gold and silver mines. Despite the harsh and arid climate in Death Valley manage to survive about 900 different plant species. In addition, there is found a lot of small desert insects, lizards, snakes, rodents and coyotes. The most surprising occupant of Death Valley is a fish called karpozubikom Devil's Hole. This species has managed to survive here for thousands of years, despite dramatic changes in its habitat. Taklamakan Desert - a desert, snow-covered Taklamakan Desert (also known as Taklimakan) is located in Central Asia, in Xinjiang Uygur Autonomous Region of China. She is known as one of the largest sand deserts in the world. In the Tarim Basin, it covers an area of ??270,000 sq km (100,000 sq mi): 1000 km (620 miles) long and 400 km (250 miles) wide. Taklamakan is a desert with a cold climate. In February 2008, in the desert was the biggest snowfall, and there was recorded the lowest temperature, -32 degrees Celsius (-25.6 Fahrenheit), the first time the earth's surface was completely covered with a thin layer of snow, which reaches a thickness of 4 cm (1.6 inches).
