Which of the following are the evidences of the phenomenon of continental drift?
I. The belt of ancient rocks from Brazil coast matches with those from Western Africa.
II. The gold deposits of Ghana are derived from the Brazil plateau when the two continents lay side by side.
III. The Gondwana system of sediments from India is known to have its counterparts in six different landmasses of the Southern Hemisphere.
Select the correct answer using the code given below.
- A.I and III only
- B.I and II only
- C.I, II and III
- D.II and III only
▶ Answer & Explanation
Correct answer: C. I, II and III
Alfred Wegener's theory of continental drift presented several lines of evidence. The matching geological formations, such as the ancient rock belts of Brazil and West Africa, support the idea of a once-connected landmass. Similarly, the distribution of mineral resources, like gold deposits in Ghana, can be explained by their original position on the Brazilian plateau before continental separation. Furthermore, the presence of similar sedimentary rock sequences, like the Gondwana system, across continents in the Southern Hemisphere provides strong evidence for their former adjacency.
