Consider the following statements regarding continental drift theory Continental drift theory had been propounded by Alfred Wegner All the landmasses were once part of the super continent or Pangaea. As a support to the theory, Wegener presented jig-saw-fit Select the correct answer using the following codes. Correct Answer 1, 2 and 3

The correct answer is Option C, i.e 1, 2 and 3.

  • Continental Drift Theory had been proposed by Alfred Wegener (1912) and F. B. Taylor (1908). Hence, Statement 1 is correct.
  • As per this theory the earth crust was once made of two parts: Pangaea (unified form of all the landmasses), and Panthalassa (huge water body surrounding Pangaea). Hence, Statement 2 is correct.
  • During the carboniferous period, this Pangaea was started to break apart into two parts: Laurasia (Angaraland), Gondwanaland.
  • As the support to the theory, Wegener had presented several pieces of evidence like jig-saw-fit (opposite coast of Atlantic can be fitted together as two cut off pieces of wood can be refitted), identical species of plants and animals found on many parts of the world, evidence of paleoglaciation in Brazil, India, Australia, Antarctica, etc. Hence, Statement 3 is correct.
