Physically, Antarctica is divided in two by the Transantarctic Mountains, close to the neck between the Ross Sea and the Weddell Sea. Western Antarctica and Eastern Antarctica correspond roughly to the western and eastern hemispheres relative to the Greenwich meridian. [note 1] West Antarctica is covered by the West Antarctic Ice Sheet.
It is bounded by Queen Maud Land in the West and by the Ross Dependency in the East. The Australian Antarctic Territory is the largest of any claims to the continent, and covers nearly 5.9 million square kilometres. [3] This makes up about 42% of Antarctica, and would cover about 80% of Mainland Australia. [4]
