Most Fascinating Deserts

01. Taklamakan(Central Asia):a desert covered with snowfall

Taklamakan is one of the largest sandy deserts in the world, ranking 15th in size in a ranking of the world's largest non-polar deserts. It covers an area of 270,000 km2 (100,000 sq mi) of the Tarim Basin, 1,000 kilometres (620 mi) long and 400 kilometres (250 mi) wide. It is crossed at its northern and at its southern edges by two branches of the Silk Road as travelers sought to avoid the arid wasteland.
In 2008, China's biggest desert experienced its biggest snowfall and lowest temperature after 11 consecutive days of snow. Snow is rare in the desert that covered 337,600 square kilometers, never before had the whole desert been covered.

02. Lencois Maranhenses(Brazil):a desert' with lagoons

It seems incredible, but in a country that keeps around 30% of the fresh water and shelters the largest rain forest in the world, we can find a desert. Located in the State of MaranhAÐo, on the north shore of Brazil, the Lencois Maranhenses National Park is an area of about 300 square kilometers (155,000 ha) of blinding white dunes and deep blue lagoons, forming one of the most beautiful and unique places in the world. The dunes invade the continent over 50km (31 miles) from the cost, creating a landscape that reminds a white bed sheet, when seen from above.
But you may ask: -Lagoons?? You told me it was a desertaE| Yes, what defers this region from a desert is the amount of rain that drops over the dunes, creating ponds of crystal clear water on the depression between dunes. Despite its desert-like appearance, LenAÒA3is Maranhenses records an annual rainfall of 1,600mm (i.e. 62.9 inches), 300 times more than in the Sahara. During the period of drought, the lagoons evaporate and become completely dried. After the rainy season, the lagoons are home of many species of fish, turtles and clams. The mystery in this story lies in the fact that when the lagoons fill up, life comes back, as if theyhad never left the place. One of the hypotheses to explain the phenomenon is that the eggs of the fish and crabs are maintainedalive in the sand, exploding when rain comes back.

03. Salar de Uyuni(Bolivia):the world's largest salt desert

The Salar is one of the iconic images of Bolivia, a massive salt desert in the middle of the Altiplano. It is an expansive, virtually flat desert that reflects the sun in such a way as to create a mirror effect with the sky. There are several lakes in the desert with strange colours from the mineral deposits in the region.
Some 40,000 years ago, the area was part of Lake Minchin, a giant prehistoric lake. When the lake dried, it left behind two modern lakes, PoopA3 Lake and Uru Uru Lake, and two major salt deserts, Salar de Coipasa and the larger Uyuni. Uyuni is roughly 25 times the size of the Bonneville Salt Flats in the United States. It is estimated to contain 10 billion tons of salt, from which less than 25,000 tons is extracted annually.

04. Farafra(Egypt):the white desert

A main geographic attraction of Farafra is its White Desert (known as 'Sahara el Beyda,' with the word 'sahara' meaning a desert). The White Desert of Egypt is located 45 km (30 miles) north of Farafra. The desert has a white, cream color (it is truly white, in clear contrast with the yellow deserts elsewhere) and has massive chalk rock formations that have been created as a resultof occasional sandstorms in the area.

05. Atacama(Chile):the flourished desert

The Atacama Desert occupies the largest amount of the Chilean territory located north of the 29th parallel. The area located on the coast between Arica and Antofagasta appears in the Guinness Book of World Records as the driest place in the world. Nevertheless, to the south of the Tropic of Capricorn, the desert becomes kinder towards living beings. The coastal mists, "camanchacas", are more abundant south of Antofagasta and bring the humidity necessary for the maintenance of the coastal scenic vegetation. Many plants survive mainly because of the "camanchaca", and the harsh savings of water, in normal dry years, that causes them todelay important functions such as growth, to favor survival and reproduction.

06. Namib(Namibia):the only desert with elephants

South of Africa lies the Namib desert. which is less vast than the Sahara but just as impressive. It forms part of the Namib-Naukluft National Park with neighbouring Angola. The Sossusvlei sand dunes are the highest in the world, some towering at 300m highand if you are lucky enough, you can stumble across desert elephants-the Namib is the only desert in the world to have elephants. Apparently the oldest desert in the world, myriad species of plants and animals can only be found here. The Namib has fascinated geologists for years but it remains very little understood to this day. Off the coast, strong southerly winds with fogs and strong currents cause sailors to lose their way; the north coast has been named 'Skeleton Coast' due to the amount of shipwrecksfound there, some of which can be found as much as 50m inland, as the desert slowly takes over the ocean as it moves westwards.

07. Simpson Desert(Australia):the red sand desert

Australia is home to four large deserts, popularized by Mad Max: Sturt's Stoney Desert, Tanami Desert, the Great Victoria Desertand the Simpson Desert, which is also known as 'The Big Red' due to the presence of dunes of red sand. The Simpson Desert is anerg which contains the world's longest parallel sand dunes. These north-south oriented dunes are static, held in position by vegetation. They vary in height from 3 metres in the west to around 30 metres on the eastern side. The most famous dune, Nappanerica, or, more popularly, Big Red (named by Simpson Desert traveller Dennis Bartell), is 40 metres in height.

08. The Black Desert(Egypt):the desert with black stones

Located 100km northeast of the White desert, the Black Desert is a region of volcano-shaped mountains with large quantities of small black stones. The stones lie out across the orange-brown ground, so that it is not quite as black as many people may hope for. Especially after visiting the White Desert, which has formations that are really white, many will imagine a desert as dramatic as this. Climbing one of the many soft peeks, the view from the top is really nice, with similar peeks continuing on into thehaze. The Black Desert is uninhabited.

09. Antarctica:world's driest and wettest desert

Antarctica is a land of extremes. It's not inhabited year round by humans because it's simply too freezing cold. In 1983 scientists recorded extreme cold temperatures as low as -129 Fahrenheit. It's also the wettest place on Earth, but simultaneously the driest. The reason it's the aEswettestaEt is not because of rainfall; since Antarctica is covered by 98% ice, it's technically very wet. However since it's also the aforementioned coldest place in the world, it gets very little precipitation aE" less than 2 inches a year. Which makes Antarctica a desert. A brutally cold ice desert with a massive trench full of even moreaE|ice. Three for theprice of one!

10. Sahara(North Africa):world's largest desert

The Sahara, with a size of 8.6 million kmA2, is the world's largest desert, covering large parts of North Africa. Around 4 million people live there. Its maximum length is 4,800 km, running from west to east, and up to 1,200 km from north to south. Sahara covers most of Mauritania, Western Sahara, Algeria, Libya, Egypt, Sudan, Chad, Niger and Mali, and touches Morocco and Tunisia.
Sahara is very dry but there is an annual rainfall in most regions, although just a few dozen millimetres.

Who do u Blame ??

Building Collapsed In Shanghai(06/27/2009)(Daqi)
At around 5:30am on June 27, an unoccupied building still under construction at Lianhuanan Road in the Minhang district of Shanghai city toppled over. One worker was killed. According to information, a 70 meter section of the flood prevention wall in nearby Dianpu River and that may have something to do with this building collapse.
But the high-resolution photos are really amazing.
(China Daily)
Improper construction methods are believed to be the reason of last Saturday's building collapse in Shanghai, according to a report from the investigation team. The investigation team's report said that workers dug an underground garage on one side of the building while on the other side earth was heaped up to 10 meters high, which was apparently an error in construction, according to a report on eastday.com, Shanghai's official news website. "Any construction company with common sense would not make such a mistake," said an expert from the investigation team.
Earlier this week, there were also reports saying that cracks on the flood-prevention wall near the building, as well as the special geological condition in the water bank area, may be part of the reason for the collapse. "These factors are not the basic reason of this accident," said the expert.
Nine people linked to the building collapse, including the real estate developer, contractor and the supervisor for the project, have been put "under appropriate control", said the official Xinhua News Agency Sunday evening.
Firm's ignorance led to toppling of Shanghai building, report says By Will Clem and Lillian Zhang. July 4, 2009.
An official investigation into the collapse of an unfinished building in Shanghai has said that the accident was due to the construction company's "ignorance", rather than flaws in the design or building materials. However, the report stopped short of apportioning blame, and has been criticised for failing to address key issues.
The report said the collapse was caused by earth, excavated to make a 4.6-metre deep pit for an underground car park alongside the building, being piled to depths of up to 10 metres on the other side of the structure. The weight of the pile created a "pressure differential" which led to a shift in the soil structure, eventually weakening the foundations and causing them to fail. This situation "may" have been aggravated by several days of heavy rain leading up to the collapse, but investigators would not say whether this was a crucial factor. The report said the construction company - Shanghai Zhongxin Construction - "did not consider clearly" that the earth pile could have such a devastating effect.
Investigators stopped short of saying whether the company's errors were negligent or easily avoidable. However, they stressed that the building's foundations and construction materials all complied with the city's building regulations.
Huang Rong , director of the Shanghai Urban Construction and Communications Council, said inspections had shown that none of the remaining 10 apartment blocks was in immediate danger. "The surrounding buildings are now stable," he said. "The safety inspection of these homes will be the second phase of our professional team's work."
Jiang Huancheng , an architect and a lead investigator for the report, said it had been an "enormous shock" to see the site for the first time. "In my 46 years in the industry, I have never seen or heard of this," he said. "To put it simply this was ignorance leading to rashness.. We need to take this accident as an important lesson ... and ensure that it does not happen again."
Several days before the release of the report, Wu Hang , Mr Jiang's assistant, accused the construction company of incompetence and lacking "common sense". Mr Wu said the investigation had found there had been no structures to support the walls of the car park pit, and this had been a key factor contributing to the accident.

(1) An underground garage was being dug on the south side, to a depth of 4.6 meters
(2) The excavated dirt was being piled up on the north side, to a height of 10 meters
(3) The building experienced uneven lateral pressure from south and north
(4) This resulted in a lateral pressure of 3,000 tonnes, which was greater than why the pilings could tolerate. Thus the building toppled over in the southerly direction.

First, the apartment building was constructed

Then the plan called for an underground garage to be dug out
The excavated soil was piled up on the other side of the building.

Heavy rains resulted in water seeping into the ground.

The building began to shift and the concrete pilings were snapped
due to the uneven lateral pressures

The building began to tilt.

And thus came the eighth wonder of the world.
