The Gobi Desert is located in northern China and southern Mongolia, and it is typically characterized by arid landscapes rather than fertile plains. The coastal plains you mentioned would not be directly associated with the Gobi itself, as it is a desert region.
Fertile river valleys, such as those created by rivers like the Ganges and Brahmaputra, are found further south in the Indian subcontinent and not in the Gobi.
The Himalayas are a mountain range that lies to the south of the Gobi Desert. They separate the Indian subcontinent from the Tibetan Plateau. So, in terms of geographical orientation, the Gobi Desert is to the north of the Himalayas.
In summary:
- The Gobi Desert is not fertile.
- Fertile river valleys like the Ganges are to the south of the Gobi.
- The Himalayas are situated to the south of the Gobi Desert.
