The Rainbow Mountains In China

DANAXIA

Danaxia landforms are colourful rock formations at the Zhangye Danxia Landform Geological Park in Gansu Province, China. The landform is a unique type of petrographic geomorphology which is found only in China which consists of red-colored sandstones and conglomerates of largely Cretaceous age.


Research shows that about 100 million years ago, there used to be a huge inland basin here. Water carried silt from the surrounding mountains to the basin. As the result of global high temperatures the basin dried up and in these arid conditions the sediment oxidized and turned rust color. Then some 70 million years ago a 3,700-meter-thick red-colored layer formed on the basin, known as the chalk bed. On the top, there was a 1,300-meter-thick solid layer, i.e., layer of Cretaceous system, from which the peaks of Danxia Mountain gradually took shape.


Since 30 million years ago, orogenic movement has lifted the whole basin many times. Water flowing down through fissures cut through and eroded the sedimentary rock, the slope broke and receded, leaving behind the red fragmentary rocks we see now---Danxia landforms. According to experts, orogenic movement is still going on in the Danxia Mountain area, with an average rise of 0.87 meter every 10,000 years over the last 500,000 years. 


The area is fast becoming a popular tourist attraction for the sleepy town of Zhangye. A number of boardwalks and roads have been built to encourage visitors to explore the amazing rock formations. The World Heritage Committee decided to include China Danxia Landform in the World Heritage List at its 34th meeting being held in Brasilia, capital of Brazil, on August 1, 2010.

The Three Color Lakes of Indonesia

Mount Kelimutu, an active volcano is located in central Flores Island of Indonesia. The volcano contains three lakes filled with water of different colors, respectively burgundy red, pale green and dark blue. It is the only place on earth where this amazing color variation takes place.


Local people have for centuries believed that the lakes are the spiritual resting place of their ancestors. It is said the lakes change color according to the mood of the spirit – and if that is the case then the souls’ moods are constantly restless.


Tiwu Ata Mbupu (The Lake of Old People)

Tiwu Ata Mbupu (The Lake of Old People) at the western point of the volcano is typically blue. This is where it is said the spirits of the old who have led righteous lives go to rest. Tiwu Nuwa Muri Koo Fai (The Lake of Young Men and Maidens) is characteristically green. The third, Tiwu Ata Polo (the Enchanted Lake) is in dark blood red color. Flores indigenous people believe the souls of the dead people reside in the lakes.

In the last three to five years, the lakes of Kelimutu have changed in color, a phenomenon caused by the geological and chemical processes in the bottom and walls of the lakes. It could also have resulted from changes in the bacteria and microorganism populations due to changes in temperature.

Sea of Salt- The Dead Sea



The Dead Sea is also known as the Sea of Salt. This massive salt lake is spread between Israel and the West Bank to the west and Jordan on the east. The Dead Sea is 1,385 feet below sea level. Dead Sea has a salinity level of of 33.7%, which is 8.6 times saltier than the ocean.


The Dead  Sea water contains more than 35 different types of minerals including magnesium, calcium, potassium, bromine, sulfur, and iodine. The odd chemistry results in the appearance of some striking, but transient, salt crystal formations. In shallow lagoons at periodic intervals, these formations are natural works of art: billions of charged atoms in intricate geometrical formations shaped by nature into unique works of crystalline art.





The Dead Sea is 1,240 feet deep, which makes it the deepest hyper saline lake in the world. The total salinity content is 33.7 percent. Because of its high salinity content, fish and vegetation does not thrive, it does not exist at all, thus its name. The Dead sea is eight times saltier than the other oceans and it is 67 kilometer long and 18 kilometer wide. The main tributary of the sea is the Jordan River as it lies in the Jordan Rift Valley.



Visitors from all over the world come to the Dead Sea, especially those who come from the Mediterranean basin. Over thousands of years, visitors have been visiting this grand sea. Historically speaking, the place was a refugee camp for King David. The Dead Sea is also considered to be the first health resort in the world as it supplies a variety of products likes potash for fertilizers and balms. Moreover, the salt from the sea is used to create cosmetic and herbal packets.

The Mystery of Bermuda Triangle Finally Solved!

The Bermuda Triangle is a place where Hundreds of ships have been disappeared, leading to strange rumours of paranormal activity and alien invasions. The Bermuda Triangle is a region in the western part of the North Atlantic Ocean in which a huge number of aircraft and surface vessels were disappeared in a Mysterious manner that cannot be explained by human error, piracy, equipment failure, or natural disasters.



But the ships disappearances could simply been caused by methane bubbles escaping from the sea bed, according to a new report by Scientists. The principle phenomenon is - if you mix enough bubbles into water, it lowers the density of the water so that anything floating on its surface will sink. A group of American scientists came up with a simple way of putting this theory to the test.


They made bubbles in a beaker of water by feeding air into the bottom of it. Then they dropped in balls of different weights, to see which would float. Balls that floated in still water, sank when the bubbles were switched on. The same mechanism could explain why ships sink in the Bermuda Triangle. Michael Denardo, who led the team, said "If a phenomenon can be made to occur in a lab, it probably happens somewhere in the natural universe."

The Bermuda Triangle is a region in the western part of the North Atlantic Ocean in which a huge number of aircraft and surface vessels were disappeared in a Mysterious manner that cannot be explained by human error, piracy, equipment failure, or natural disasters.


The mysterious Devil's triangle covers boundary between the Straits of Florida, the Bahamas and the entire Caribbean island area and the Atlantic east to the Azores.The most of the accidents occurred along the southern boundary around the Bahamas and the Florida Straits.


The area is one of the most heavily-sailed shipping lanes in the world, with ships crossing through it daily for ports in the Americas, Europe, and the Caribbean Islands. Cruise ships are also plentiful, and pleasure craft regularly go back and forth between Florida and the islands. It is also a heavily flown route for commercial and private aircraft heading towards Florida, the Caribbean, and South America from points north.

The Moai of Easter Island

Easter Island

Easter Island is the world's most isolated inhabited island. It is also one of the most mysterious. Eastern Island is roughly midway between Chile and Tahiti. The triangular shaped island (Easter Island) is made mostly of volcanic rock.


The inhabitants of this charming and mysterious place called their land: Te Pito o TeHenua, 'the navel of the world.' It sits in the South Pacific Ocean 2,300 miles west of South America, 2,500 miles southeast of Tahiti, 4,300 miles south of Hawaii, 3,700 miles north of Antarctica.


When we think of Eastern Island we think of of huge stone carved figures -monoliths- that dot the coastline. They are called Moai and are carved from island rock.


The Moai are seen all over the island, and in different shapes, sizes, and stages of completion. Many Moaiare left unfinished at the quarry site. No one is sure yet as to what purposes did the Moai served, but outside scholarly research together with accumulated local knowledge, shows evidence that the Moai were carved by the ancestors of the present inhabitants.
