Question

Which of the following are the evidences of the phenomenon of continental drift?The belt of ancient rocks from Brazil coast matches with those from Western Africa.The gold deposits of Ghana are derived from the Brazil plateau when the two continents lay side by side.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:

Accepted Answer

Evidences of Continental Drift Theory: The radiometric dating methods developed in the recent period have facilitated correlating the rock formation from different continents across. the vast ocean. The belt of ancient rocks of 2,000 million years from Brazil coast matches with those from western Africa. The earliest marine deposits along the coastline of South America and Africa are of the Jurassic age. This suggests that the ocean did not exist prior to that time. Hence, statement I is correct. The Gondawana system of sediments from India is known to have its counterparts in six different landmasses of the Southern Hemisphere. At the base, the system has thick tillite indicating extensive and prolonged glaciation. Counterparts of this succession are found in Africa, Falkland Island, Madagascar, Antarctica and Australia. Overall resemblance of the Gondawana-type sediments clearly demonstrates that these landmasses had remarkably similar histories. The glacial tillite provides unambiguous evidence of palaeoclimates and also of drifting of continents. Hence, statement II is correct. The occurrence of rich placer deposits of gold in the Ghana coast and the absolute absence of source rock in the region is an amazing fact. The gold bearing veins are in Brazil and it is obvious that the gold deposits of the Ghana are derived from the Brazil plateau when the two continents lay side by side. Hence, statement III is correct.
