Question

Why both the Shan and Yunnan plateau are popular as dissected plateau?

Answer 1

Hint: The Yunnan plateau is situated in China. The Shan plateau is situated in the Shan state of Eastern Myanmar. This plateau is the country’s main source of lead, zinc, and silver materials. It is the area of major teak forests.

Complete answer:
The Yunnan plateau and the Shan plateau, both have slopes steeply on the west side. The rivers like the Mekong and the Salween flow across it. Since both the plateau are having rivers cutting across them and hence creating valleys. Therefore they are referred to as the dissected plateau.

Additional Information:
Shan Plateau is the crystalline massif forming the eastern part of Myanmar. It is the forming part of the Indo-Malayan mountain system. This plateau is crossed by the deep trench of the Salween River in the east. Whereas it is bordered by the upper course of the Irrawaddy River to the west. It is seamed and ribbed by mountain ranges, which are splitting it up and running into each other. The mountain ranges have the average elevation of between 4000 to 5000 feet. At some places it has peaks rising to more than 8000 feet.

The Yunnan Plateau subtropical evergreen forests are the endangered ecoregion in the southwestern part of China. These forests have covered the western parts of the Yungui Plateau. But these have been significantly reduced and replaced with the agricultural land uses. The Yunnan forests and its neighbouring Guizhou Plateau are broadleaf.

Note:
The Yunnan–Guizhou Plateau is the highland region located in southwest China. It is mainly spread over the provinces of Yunnan and Guizhou.
