West Antarctica and Marie Byrd Land have elevations of up to 1.5 to 2 kilometers on the surface of the WAIS. In contrast, East Antarctica has interior elevations on its ice sheet of over 4 kilometers. [38] The West Antarctic Rift System (WARS [39]) that evolved over the last hundred million years, includes all or part of Marie Byrd Land. [40]
Geographical map of Antarctica. Lying on the Pacific Ocean side of the Transantarctic Mountains, West Antarctica comprises the Antarctic Peninsula (with Graham Land and Palmer Land) and Ellsworth Land, Marie Byrd Land and King Edward VII Land, offshore islands such as Adelaide Island, and ice shelves, notably the Filchner-Ronne Ice Shelf on the Weddell Sea, and the Ross Ice Shelf on the Ross Sea.

The presence of the West Antarctic Rift System has resulted in volcanism along the border between West and East Antarctica, as well as the creation of the Transantarctic Mountains. [62] East Antarctica is geologically varied. Its formation began during the Archean Eon (4,000 Ma–2,500 Ma), and stopped during the Cambrian Period. [63]
<p>Chances are you make it through most days without sparing a thought for Antarctica. At just over 5.4 million square miles, it's a massive chunk of land that is nearly twice the size of ...
Marie Byrd Land makes up a large portion of West Antarctica, consisting of the Area below the Antarctic Peninsula. The Marie Byrd Land is a large formation of volcanic rock, characterized by 18 exposed and subglacial volcanoes. 16 of the 18 volcanoes are entirely covered by the antarctic ice sheet. [8]
