Answer 1

Answer:

For the Doctor Who episode, see Marco Polo (Doctor Who). For the Doctor Who audio story, see The Roof of the World. For the ancient geography of this region, see Mount Imeon.

The Roof of the World or Top of the World is a metaphoric description of the high region in the world, also known as High Asia. The term usually refers to the mountainous interior of Asia, including the Pamirs, the Himalayas, the Tibet, the Tian Shan, and the Altai Mountains.
