Question

Select the correct location on the map.
Scientists have found ancient rock formations dating to the late Proterozoic eon in South America. These ancient rocks can be found from the eastern edge of South America's continental shelf, which extends just off the coast of Brazil, to the interior of the continent. This general location is indicated by a green circle on the map below.

Scientists have also found rock formations made out of the same type of rock and from the very same eon at another location. The location of this second group of rock formations strongly supports the current theory of plate tectonics.

Where is the second rock formation most likely located?

Answer 1

Based on the information provided, the second rock formation made from the same type of rock and from the late Proterozoic eon is likely to be located at a site that aligns with the current theory of plate tectonics, which includes the movement of continents and the presence of similar rock formations across different geographic locations.

Considering this, the second rock formation is most likely found in West Africa. This is because the geological formations and rock types present in South America match those found on the west coast of Africa, particularly due to the historical connection of these continents when they were part of the supercontinent Gondwana.

Therefore, the second rock formation, which shares characteristics with the ancient formations found in Brazil, would likely be located in a region of Africa that is aligned with that tectonic history.
