Antarctica: Geography and Research Insights

Antarctica, the least understood continent, is larger than many realize and mostly covered by a thick ice sheet. This ice holds vast amounts of freshwater and conceals geological features like mountains and canyons. Beneath the ice, subglacial lakes may harbor unknown life forms. The continent's potential natural resources, such as oil, are subject to international treaties, but geopolitical tensions could rise as these resources become more accessible.
