Question

GIVE REASON WHY:

The Siberian Plain becomes swampy and marshy.

The Plateau of Tibet is called the 'Roof of the World'.​

Answer 1

1. Many of the deposits on this plain result from ice dams that reversed the flow of the Ob and Yenisei rivers, redirecting them into the Caspian Sea, and perhaps the Aral Sea as well. It is very swampy and soils are mostly peaty Histosols and, in the treeless northern part, Histels.

2 . It's called the "Roof of the World" with good reason — the Tibetan Plateau stands over 3 miles above sea level and is surrounded by imposing mountain ranges that harbor the world's two highest summits, Mount Everest and K2.
