南极是目前世界上惟一保存着“自然真面貌”的大陆。那里的环境基本上没有受到人类活动的影响,那里的空气和冰雪,也没有受到大工业的污染。南极是一个了解自然界的本来面目,研究地球的过去、现在和将来,理想的科学研究的“天然实验室”。几亿年以前的地球到底是什么样子?德国气象学家魏格纳提出了“大陆漂移”学说。他认为,在1.6亿年以前,现在地球上一块块分散的大陆是连在一起的一块超级大陆,称“冈瓦纳大陆”。后来由于板块运动,使这个大陆最终分离、解体。首先分裂出来的是 Antarctica is the only continent in the world that currently holds the “natural appearance.” The environment there has basically not been affected by human activities. The air and ice there have not been contaminated by large industries. Antarctica is a “natural laboratory” that understands the natural world and studies the past, present, and future of the earth and ideal scientific research. What did the Earth look like hundreds of millions of years ago? German meteorologist Wegener proposed the theory of “continent drifting”. He believes that 160 million years ago, the scattered continents on the Earth are now linked together as a super continent called the Gondwana Continent. Later, due to the plate movement, the continent was eventually separated and disintegrated. The first thing that splits up is
