The mountain building in Himalayas began

  • A.about 45 million years ago
  • B.when the continental plates of India and Eurasia converged on each other
  • C.both (a) and (b)
  • D.None of the above

Answer: C

Both statements are true.

The Indian plate, drifting north after breaking from Gondwana, met the Eurasian plate roughly 45 to 50 million years ago. The sediments of the intervening Tethys Sea were crushed and folded upward, and the collision continues, which is why the Himalayas still rise by about a centimetre a year and the region is seismically active.
