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:
Answer
I, II and III
I. Correct. Geological evidence supports continental drift: the ancient rock belts on the Brazil coast closely match those of Western Africa in age and structure.
II. Correct. The Ghana gold deposits are cited as a classic correlation with the Brazil plateau, suggesting the two landmasses were once joined.
III. Correct. Gondwana sediments of India have clear counterparts across multiple Southern Hemisphere landmasses such as Africa, South America, Australia, Antarctica and Madagascar, supporting a former unified Gondwanaland.
Hence, all three statements are correct.
