The Antarctic landmass dates back to 650 million years. It was an amalgamated southern supercontinent called Gondwana. This landmass centered around the present-day Antarctica. Human beings did not exist as their civilization is only 12,000 years old. The climate at that time was warm and landmass flourished with a vast variety of flora and fauna. The study of this region shows that Gondwana prospered for 500 million years. But then the dinosaurs got wiped out and mammals began to appear. The landmass disintegrated into countries and India, the Himalayas and South America was formed. This left Antarctica frigid at the bottom of the earth. Today, it stores the key to the significance of coridelleran folds and pre- Cambrian granite shields, ozone and carbon layers as well as a study of the evolution and extinction. This can help us to understand in a better way the formation of continents and mountains like the Himalayas as we find them in the modem world. Its ice-folds hold over half-million-year-old carbon records that are so crucial for the study of the Earth’s past, present and future, thus trapping the world’s geological history in Antarctica.

Answer 2

$\huge\underline\mathfrak\pink{♡Answer♡}$

The study of this region of Antarctica gives us insight into the world's geological history. It gives an idea, how the earth was like, before it drifted into continents and countries. It shows how slight changes in the climate can change the shape of the region. It gives explanation how the climatic conditions of the earth were not favourable for life. All secrets are embedded in the layers of ice in the form of half million year old carbon records.
