Question

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.

1. A. I and III only
2. B. I and II only
3. C. I, II and III (Correct answer)
4. D. II and III only

Correct Answer

Option C — I, II and III

Detailed Solution & Explanation

The correct answer is I, II and III.

Key Points

• All three are classical evidences of continental drift: the geological rock belt continuity between Brazil and West Africa (I), the hypothesis that Ghana's gold deposits share origin with the Brazilian plateau (II), and the presence of Gondwana flora/fauna (especially Glossopteris) across six Southern Hemisphere landmasses (India, Africa, South America, Antarctica, Australia, Madagascar) (III). All three are correct.
