Which Has Higher Average Elevation: Saudi Arabia or Tibet?

Tibet has a dramatically higher average elevation.

• Tibet (Tibet Autonomous Region): Mean elevation ~4,500 m (14,800 ft). Known as the "Roof of the World"; includes Himalayan peaks (Everest 8,848 m), vast high plateau.
• Saudi Arabia: Mean elevation ~665 m (2,180 ft). Western highlands (Hejaz/Asir) reach 3,000 m, but most of the country is low-lying desert (Najd plateau ~1,000 m, Empty Quarter near sea level).

Tibet's average elevation is nearly 7 times higher than Saudi Arabia's. It is the highest region on Earth.
