The geography of Tibet consists of the high mountains, lakes and rivers lying between
Central,
East and
South Asia. Traditionally, Western (European and American) sources have regarded Tibet as being in
Central Asia, though today's maps show a trend toward considering all of modern China, including Tibet, to be part of
East Asia.
Tibet is often called "the roof of the world," comprising table-lands averaging over 4,950 metres above the sea with peaks at 6,000 to 7,500 m, including
Mount Everest, on the border with Nepal.
