Major Inland Seas & World Lakes GK Questions & Answers
Inland seas and major lacustrine systems represent critical hydrological, geological, and ecological reservoirs across the globe, formed primarily through tectonic rifting, glacial scouring, and volcanic processes. The Caspian Sea stands as the world's largest enclosed inland body of water by both surface area (371,000 square kilometres) and volume, bounded by five littoral nations—Kazakhstan, Russia, Turkmenistan, Azerbaijan, and Iran—functioning as an endorheic basin primarily fed by the Volga River. In terms of freshwater reserves, Lake Baikal in Siberian Russia is the world's oldest (25 million years) and deepest (1,642 metres) lake, holding approximately twenty percent of Earth's unfrozen surface fresh water within an active continental rift zone. Across North America, Lake Superior represents the largest freshwater lake by surface area (82,100 square kilometres) within the Laurentian Great Lakes system. In the East African Rift, Lake Tanganyika is recognized as the world's longest freshwater lake, while Lake Victoria forms Africa's largest tropical water body and the primary source of the White Nile. Additionally, the hypersaline Dead Sea occupies Earth's lowest terrestrial elevation at 430 metres below sea level.
