Explain the process of thermoluminescence dating
another group of geologists propose crustal thinning theory, block faulting and a ridge formed in the region owing to thinning and asserts that development of this ridge augmented the coral growth in the region and in turn coral cover acted as a `sand trapper’.
Back in 2002, there were unsuccessful attempts by actual scientists to debunk the “ancient civilization” theory and inject some needed common sense and real science into the discussion.
It’s simply a natural tombolo: “a deposition landform in which an island is attached to the mainland by a narrow piece of land such as a spit or bar.” The conspiracy theorists and some religious fundamentalists disagree.
It’s been called the Adam bridge, the Rama, Sethu (also Rama Setu – setu is Sanskrit for bridge), Ramar and the Hanuman bridge, and Setubandhanam.
Studies have variously described the structure as a chain of shoals, coral reefs, a ridge formed in the region owing to thinning of the earth’s crust, a double tombolo, a sand spit, or barrier islands.
It has been reported that this bridge was formerly the world’s largest tombolo before it was split into a chain of shoals by the rise in mean sea level a few thousand years ago.
The final paragraph of this tale claims, This information may not be of much importance to the archeologists who are interested in exploring the origins of man, but it is sure to open the spiritual gates of the people of the world to have come to know an ancient history linked to the Indian mythology. Homo sapiens – them back then: they were Homo erectus, a much more primitive version of our species, which existed even before Neanderthals!During the Paleolithic, humans grouped together in small societies such as bands, and subsisted by gathering plants and fishing, hunting or scavenging wild animals.The Paleolithic is characterized by the use of knapped stone tools, although at the time humans also used wood and bone tools.Another NASA mission in 2002 produced a second photograph of the region (photo here) which, of course, spun the online conspiracy theorists off on a wild goose chase trying to “prove” it was the remains of a human-made structure connecting Sri Lanka with India. Wikipedia tells us it’s long been known as a natural formation, but that geologists differ in their views as to how it formed: In the 19th century, there were two prevalent theories explaining the structure.One considered it to be formed by a process of accretion and rising of the land, while the other surmised that it was formed by the breaking away of Sri Lanka from the Indian mainland.
