’The worlds geological history is trapped in Antarctica. ‘How is the study of this region useful to us?    

Answer:

The world's geological history is trapped in Antarctica. This is because the modern world is battling with increasing population and excessive burning of fossil fuels has created a:blanket of carbon dioxide around the world which is increasing the average global temperature. The concretization of land has worsened the situation. But Antarctica is relatively untouched in this respect since it has never had human population.   Antarctica is a crucial element in the debate on climate change because it is relatively 'pristine'. More importantly, it holds in its ice-cores half-a million-year-old carbon records, trapped in its layers of ice. It embodies all that is prehistory: cordilleran folds, pre-Cambrian granite shields, ozone and carbon; evolution and extinction. Hence, to study and examine the earth's past, present and future, Antarctica is the best place to go. These are the factors that make Antarctica very important, geologically.
