Q: Which of the following is a major tectonic plate?
  • A. Cocos plate
  • B. Arabian plate
  • C. Pacific plate
  • D. Nazca plate
Correct Answer: Option C - The theory of plate tectonics was formulated in the 1960. According to the theory, earth has, a rigid outer layer, known as the lithosphere, which is typically about 100km thick and over lies a plates layer called the asthenosphere. The lithosphere is broken up into seven very large continental- and ocean sized plates, six or seven medium sized plates, and several small ones. There are seven major plates- * Pacific Plate, North American Plate, Eursian Plate, African Plate, Antarctic Plate, Indo-Australia Plate and South American Plate.
