Antarctica South America Continent and its Countries
1. Antarctica is the least populated and the 5th largest continent on earth.
2. Around 30 countries govern Antarctica, all of which are signatories to the Antarctic Treaty System of 1959. As per the terms of the treaty, there are prohibitions regarding disposing of nuclear waste, conducting nuclear explosions, mining, and other military activities in Antarctica.
3. Antarctica is mainly a polar desert, covered by the Antarctic ice sheet with an average thickness of about 1.9 km. It has a long period of darkness or light with very low precipitation.
4. Unlike the Arctic in the Northern Hemisphere, which is ice floating on water, Antarctica is a continent on which thick ice sheets cover the bedrock.
5. There are massive stretches of sea ice (frozen sea water, detached from the land) surrounding Antarctica. Sea ice is used for a range of wildlife, like Emperor Penguins and krill.
6. Sea ice changes seasonally; scientists are now showing that climate change is affecting the timing and extent of sea ice.
