Indias major land clays It is forthwith generally accepted that Indias geographic position, Continental outline, and basic geologic structure resulted from the shifting of enormous, rigid, crustal slabs called tectonic plates. These plates, which form the entire surface layer of the Earth, collide or fall behind by one another as they move across the underlying layer of molten material. India forms the northwesterly portion of the Indian-Australian photographic plate. The land Hundreds of megs of geezerhood ago, ofttimes of Indias landmass was a fragment of an ancient southern-hemispheric supercontinent cognize as Gondwana, or Gondwanaland (which to a fault included what are now South America, Africa, Australia, and Antarctica). With the shifting of tectonic plates, Gondwanaland began to break up, and the Indian fragment, carried by the Indian-Australian Plate, began to drift s humbledly due north toward the much larger Eurasian Plate. When they finally collided ( approximately 50 million years ago), the northern move on of the Indian-Australian Plate was flip under the Eurasian Plate at a low angle. The collision reduced the speed of the onset plate, but up to now today the underthrusting, or subduction, of the plate continues. The cause of the collision and go along subduction are numerous and extremely complicated.

An burning(prenominal) consequence, however, was the slicing off of crustal quaver from the top of the underthrusting plate. These slices were thrown punt onto the northern edge of the Indian landmass and came to form much of the Himalayan mountain sy stem. The advanced mountains-to arouseher w! ith vast amounts of sediment decay from them-were so heavy that the Indian-Australian Plate just south of the lean was forced downward, creating a govern of crustal subsidence, or geosyncline. Continued rapid erosion of the Himalayas added to the sediment accumulation, which was subsequently carried by mountain streams to touch the geosyncline and cause it to sink more.
