Theory:

Drainage
  • Central highlands is the origin for most of the rivers in Asia.
  • Major rivers that flow towards the north and drain into the Arctic Ocean are Ob, Yenise and Lena. These rivers remain frozen during winter.
  • South Asia has many perennial rivers (e.g.) Brahmaputra, Indus, Ganga and Irrawaddy. They originate from the high snow-covered mountains that do not freeze during winter.
  • Rivers in West Asia: Euphrates and Tigris.
  • Rivers flowing in the south and southeastern parts of Asia are The Amur, Huang He, Yangtze and Mekong. The longest river in Asia: Yangtze
