Explanation:

Evidences in support of continental Drift:
(i) “Jig saw” fit- Wegener was struck by the geographical similarity between the opposite coasts of the atlantic ocean.the outlines of the two coasts appears to be the detached portion of the other ie. The east coast of north and South America can be exactly fit into the left coast of Africa and Europe.

(ii) Geological structure- there is remarkable similarity in geological structure along the two coasts of Atlantic. The best example is provided by the Appalachian mountains of north America which come right up to the coast and continue their trend across the ocean in old Hercynian mountains of south west Ireland, Wales and central Europe. The opposite coasts of Africa and Brazil display even greater resemblance in their structure and rocks.

(iii) Permo-carboniferous glaciations- it presents a strong proof that at one point of time these land masses were assembled together , since the evidences of this glaciation are found in Brazil, Falkland island, South Africa, Indian peninsula as well as Australia. It is difficult to explain these extensive glaciations on the basis of existing distribution of landmass and water. According to Wegener at the time of Pangaea, the South Pole was situated near Durban of the present coast of south Africa.
(iv) Similar Fossil remains of terrestrial animals are found on both coasts of the Atlantic. This cannot be possible if the two landmasses were not joined as it quite impossible for these animals to swim across the Atlantic.
