Antarctica is for the most part a vast, icy emptiness, some 14 million square kilometers of which is almost completely covered by an ice sheet with an average thickness of over 2,000 meters. Only about 2% of the land mass is ice-free, and about half of this is in the Ross Dependency...

The eastern two thirds of Antarctica is covered by an ice sheet so large that if it melted the sea would rise by 52 metres [~yards]. Most scientists had once thought this ice sheet was largely invulnerable to climate change, but not any more. And our new research, published inNature, r...
The South Pole is covered in ice. The Antarctic icesheet (南极冰盖) covers thousands of miles. Antarctica is under 1.6miles of ice. That’s about 2 kilometers of ice.Recently, scientists have discovered that the land isn’t 100% flat; under the ice is a large hidden landscape (风景) ...
Antarctica is a place of extremes. It is the coldest, highest, driest and windiest continent on Earth. Antarctica is a continent 1 (cover) by an inland ice sheet up to 4.8km thick, 2 (hold) about 90% of the world’s fresh water. The ice sheet is 3 heavy that it has pushed the ...
根据后文的“Damage to the environment occurs as people come looking for resources beneath the ice, or carelessly leave their garbage behind.(当人们到冰下寻找资源,或不小心把垃圾留在那里时,环境就会受到破坏。)”可知,随着人类对南极洲的开发和探险,南极洲的环境遭到了破坏。D选项“Yet, Antarctica’s ...
Ice will deform under large stresses applied for extended periods of time. Consequently, all glaciers and ice sheets experience the flow of ice through deformation. Antarctica has the world’s largest ice sheet by an order of magnitude (Greenland’s being next-largest), and it has the highest...

For now, the ice melt and corresponding sea-level rise remains at a manageable level. In the past 40 years, Antarctica's contribution to global sea level rise has only been a half an inch. But that pace is increasing as theclimate warms faster. ...
