Geography of Antarctica

The continent of Antarctica is the southernmost continent of the world and is surrounded by the Southern Ocean. Antarctica states that it is the fifth largest continent covering an area of 14.4 million square kilometers. The coastline of Antarctica extends up to 17,968km. Between the Ross Sea and the Weddell Sea the Tran Antarctic Mountain has segmented Antarctica into two parts. The part east of the Ross Sea and West of the Weddell Sea is called the Western Antarctica and the remaining half is called the Eastern Antarctica. 98% of this continent is covered by ice sheet that accounts for almost 90% of the world's ice. The precipitation is quite low in most of the areas. The west of Antarctica is bounded by West Antarctic Ice Sheet.

The topography of Antarctica includes numerous mountains and high points. Mount Vinson Massif is the highest mountain peak located in the Ellsworth Mountain Range.

Antarctica consists of many volcanoes like the Mount Erebus, Deception Island. The Erebus is the southernmost volcano and the Deception Island is noted for its massive irruption in 1970. Minor irruptions and lava flows are common phenomena of this region. An under water volcano was located in 2004 in the Antarctic Peninsula by the American and Canadian researchers. Of more than 70 lakes found in Antarctica, Lake Vostok is the largest of the sub glacial lakes.
