Antarctic:
Antarctica is divided into East Antarctica and West Antarctica. East Antarctica extends from 30 west longitude to170 east longitude, including cortese Land, Maud Land, Enderby Land, Wilkes Land, George V Coast, Victoria Land, Antarctic Plateau and Pole. Area10180,000 square kilometers.
West Antarctica lies between 50 ~ 160 west longitude, including Antarctic Peninsula, Alexandria, Ellsworth Land and Bird Land (Mary Bird Land), covering an area of 2.29 million square kilometers.
2. Different plant resources
The zonal vegetation types in Beijing are warm temperate deciduous broad-leaved forest and temperate coniferous forest. The types of surface vegetation in low mountain areas below 800 meters above sea level are Quercus variabilis forest, Quercus acutissima forest, Pinus tabulaeformis forest and Platycladus orientalis.
In Zhongshan above 800 meters above sea level, the forest coverage rate increases, and the lower part is dominated by Quercus liaotungensis forest. There are many birch trees at the altitude of 1000 m to 1800~2000 m, which are the dominant shrubs of Lespedeza bicolor, Corylus heterophylla and Spiraea in the severely damaged forest communities. The mountain grass meadow grows on the top of the mountain at an altitude of 1800~ 1900 meters.
The Antarctic climate is cold, and plants are difficult to grow. Occasionally, some plants such as moss and lichen can be seen. There are birds and marine animals near the coast and islands.
3. Different landforms
The mountainous area of Beijing is 10200 square kilometers, accounting for 62% of the total area, and the plain area is 6200 square kilometers, accounting for 38% of the total area. The terrain of Beijing is high in the northwest and low in the southeast. The average altitude in Beijing is 43.5 meters. The elevation of Beijing plain is 20 ~ 60m, and that of mountainous area is generally 1000 ~ 1500m.
The mountains across the Antarctic divide the Antarctic continent into two parts. East Antarctica, with a large area, is an ancient shield and quasi-plain, which runs across the Antarctic mountains and stretches on the edge of the shield. West Antarctica is a small fold belt composed of mountains, plateaus and basins.
There is a subsidence zone between east and west, extending from Ross Sea to Weddell Sea. Antarctica is the highest continent on earth, with an average elevation of 2350 meters. The highest point is Luoyusheng Mountain in Marybird Land, with an altitude of 5140m. The mainland is almost completely covered with ice and snow, with an average thickness of1880m and a maximum thickness of over 4000m.
