  南极洲(Antarctica)全境为平均海拔2350米的大高原,是世界上海拔最高的大洲。

  

南极洲

 

  南极洲位于地球南端,四周为太平洋、印度洋和大西洋所包围,边缘有别林斯高晋海、罗斯海、阿蒙森海和威德尔海等。包括大陆、陆缘冰和岛屿,总面积1405.1万平方千米,约占世界陆地总面积的9.4%。

  横贯南极的山脉将南极大陆分为两部分。东南极洲,面积较大,为一古老的地盾和准平原,横贯南极山脉绵延于地盾的边缘;西南极洲面积较小,为一褶皱带,由山地、高原和盆地组成。东西两部分之间有一沉陷地带,从罗斯海一直延伸到威徳尔海。

  

南极洲

 

  南极洲大陆平均海拔近几千米,最高点玛丽·伯德地的文森山海拔5140米。大陆几乎全部被冰雪所覆盖,冰层平均厚度 有1880米,最厚达4000米以上。大陆周围的海洋上有许多高大的冰障和冰山。全洲仅2%的土地无长年冰雪覆盖,被称为南极冰原的“绿洲”,是动植物主要生息之地。“绿洲”上有高峰、悬崖、湖泊和火山。南极大陆共有两座活火山,那就是欺骗岛上的欺骗岛火山和罗斯岛上的埃里伯斯火山(又译埃拉波斯火山)。欺骗岛火山在1969年2月曾经喷发过,使设在那里的科学考察站顷刻间化为灰烬,直到现在,人们仍然对此心有余悸。

  Antarctica (Antarctica) throughout for an average altitude of 2350 meters highplateau, is the world's highest altitude continents.

  Located in the southern tip of the earth around Antarctica, surrounded by the PacificOcean to India, and the Atlantic, the edge of a belli, Gao Jinhai Ross sea, Amundsensea and Weddell sea. Including the mainland, Lu Yuanbing and the islands, the total area of 14051000 square km, accounting for about 9.4% of the world's total land area.

  The Transantarctic Mountains in Antarctica the Antarctic continent is divided into two parts. East Antarctica, the area is larger, as an ancient shield and peneplain, trans Antarctic Mountains stretches to the edge of the shield; the West Antarctic area is small, a fold belt, composed of mountains, plateaus and basins. There is a subsidencezone between two part of things, extending from the Ross sea till the Weddell sea.

  The continent, an average elevation of several thousand meters, the highest point inMarie Byrd land Vincent Hill 5140 meters above sea level. The mainland almost all covered by ice and snow, the average ice thickness of 1880 meters, the more than 4000 meters thick. There are many tall ice barrier and icebergs around the continentocean. The entire island is only 2% of land without permanent snow and ice coveredAntarctic ice, known as the "oasis", is the main habitat of the animal and plant. "Oasis" there are peaks, cliffs, lakes and volcanoes. The Antarctic continent has a total of two active volcanoes, it is to deceive the deception island volcano island and Ross islandon the mount Erebus volcano (also translated Ella Persian volcano). Deception islandvolcano in 1969 February eruption have been located there, make the scientific research station in an instant into the ashes, until now, people still have a lingering fear.
