Question

Which Plateau (पठार) is known as the ‘Roof of the World’?

Answer 1

Central Asia's Tibetan Plateau is justifiably nicknamed "the roof of the world"-its average elevation is more than 4,500 meters (14,764 feet).

Answer 2

The Tibetan Plateau is sometimes called the "Roof of the World" because it is 3 miles (4.8 km) above sea level and is home to the mountain range that surrounds the world's two highest peaks, Mount Everest and K2 Plateau.
