Exercise 11. Read the passage and answer the questions that follow.

 

For many years Antarctica was thought to be only an archipelago with islands tied together above sea level by ice. It was thought to be made up of two small subcontinents — East Antarctica, the larger, and West Antarctica, containing the Antarctic Peninsula. The two continents were supposed to be separated below sea level. Modern geophysical studies, however, have revealed a fairly complete picture of the Antarctic landform below its ice cover. Now we know that West Antarctica is connected to the main part of the continent by a chain of mountains well above the sea level. The bedrock of much of East Antarctica appears to be above sea level; some of it (in the Transantarctic Mountains) is far above sea level. Whether mineral wealth lies hidden by ice is unknown. No deposits rich enough to be economically useful have been found. Interpretation of continental structure is an important objective of any extensive geologic investigation, yet except for the earth's ocean basins, no area the size of Antarctica is so geologically unknown. With 98 percent of the continent covered by ice, it is extremely difficult to decipher the continent's general structure.
