Please describe how the giant mountain range to the north of India impacts the geography of India.

Among the most dramatic and visible creations of plante-tectonic forces the lofty Himalayas (stretch 2,900 along the border between Indian and Tibet) This immense mountain range began to form between 40 and 50 million years ago, when two large lad masses, Indian and Eurasia, driven by plant movement, collided. Because both these continental land masses have about the same rock density.

Due to Himalayas entire India is brought under the sway of moist laden winds for a few months. The Himalayas block the monsoon winds and confine them to the Indian subcontinent. Without monsoons, India would have been a desert. ... 90% of the rainfall in India is due to monsoon.
