Explanation:

The Pat-kai or Patkai Bum (meaning "to cut (pat) chicken (Kai)" in Tai-Ahom language) are the hills on India's north-eastern border with Burma or Myanmar. They were created by the same tectonic processes that created the Himalayas in the Mesozoic.

Three mountain ranges come under the Patkai. The Patkai-Bum (Burmese Kumon Taungdan), the Garo-Khasi-Jaintia, and the Lushai Hills, highest point Phawngpui Tlang, also known as 'Blue Mountain'. The Garo-Khasi range is in the Indian state of Meghalaya. Mawsynram and Cherrapunji, on the windward side of these hills are the world's wettest places, having the highest annual rainfall.
