Key Points

  • Statement 1 is correct: Lake Turkana is the world's largest permanent desert lake, and also the largest alkaline lake on Earth.
  • It lies in the Great Rift Valley and is fed chiefly by the Omo river, which supplies most of its inflow; it has no outlet, so water is lost only through evaporation — which is why it is saline and alkaline.
  • Statement 2 is incorrect, and is the key to the question: the lake lies in KENYA, with its northern tip extending into Ethiopia.
  • It is not in South Sudan, and it lies in the East African Rift Valley — not along the eastern fringe of the Sahara.
  • Statement 3 is correct: the Lake Turkana National Parks (Sibiloi, Central Island and South Island) are inscribed as a UNESCO World Heritage Site.
  • The lake is nicknamed the 'Jade Sea' for the striking turquoise-green colour imparted by algae.
  • Additional context: the Turkana Basin is one of the world's richest hominid fossil sites — the 'Turkana Boy' Homo erectus skeleton was found here, earning the area the name 'Cradle of Mankind'.
