b. Arctic
c. European
d. African
ANSWER: Antarctica
Geologists have found evidence supporting the hypothesis that an Indian subcontinent was part of Antarctica a billion years ago but were separated and re-united several times due to tectonic movement of plates prior to the evolution of mankind.
- Geologists from India and Switzerland researching on evolution of the earth’s crust studied ancient rocks of the continental crust of the Eastern Ghats and discovered important clues regarding the formation of continents.
- This marks the first time researchers have been able to prove the hypothesis that a content of Antarctica and subcontinent India were once a single large continent breaking apart 1.5 billion years ago.
- With the movement of the two continents against each other at one billion years ago to form an Eastern Ghats mountain belt, there was yet another collision in 600 million years where another mountain range was created.
- Following this collision, the crust broke apart again separating India from Antarctica and there is a big ocean between the two land masses that combined several times in the history of the earth.
