Question

‘The world’s geological history is trapped in Antarctica.’ How is the study of this region used to us?

Answer 1

Antarctica used to have a tropical climate, it cooled down slowly over many millions of years for three main reasons:

1 - the continent  drifted south until it settled over the South Pole.

2 - carbon dioxide levels globally fell leading to a general cooling of the planet.

3 - a circumpolar current arose isolating Antarctica's weather systems from the rest of the world.
