Folded limestones that are exposed high elevations in the Himalayas were originally deposited as sediments in a ________.

D)late Paleozoic syncline north of the Tibetan Plateau.

Question

Quizplus · Accepted Answer

The Himalayas were formed by the collision of the Indian and Eurasian tectonic plates. Folded limestones that are exposed in the Himalayas were originally deposited as sediments in a marine basin between India and Eurasia, which was later uplifted and folded during the collision. Choice B is incorrect because the Cenozoic fault basin is located between Africa and Arabia, not the Himalayas. Choice C is incorrect because the deep ocean trench along the southern margin of India is now subducted beneath the Eurasian plate and therefore cannot have folded limestones exposed at high elevations. Choice D is incorrect because the late Paleozoic syncline north of the Tibetan Plateau is too old to have folded limestones that are exposed in the Himalayas.
