Read the passage and answer the following questions:
Since 1981, the Indian Antarctica Programme has been exploring Antarctica, a
continent with a very cold climate and harsh environment (see the white expanse at
the bottom of Fig. 2.1, which is mostly ice). In 1983, India established its first scientific
base station there, called ‘Dakshin Gangotri’ (two more bases were established later).
About 40 teams of Indian scientists have conducted research in this faraway region,
especially on the evolution of climate and environment. The settlement where the
scientists live has a library and even a post office!

2. What does the white expanse at the bottom of the map of Antarctica mostly consist
of?
