Question

Give a brief description of himalayan mountains .describe three parallel ranges of the himalayas.

Answer 1

Himalayas are the young fold mountain system formed by the folding of sedimentary rocks accumulated in the geosyncline called Tethys.They form an unstable zone and have deep valleys, high peaks and fast flowing rivers. They stretch from Indus to Brahmaputra, with a length of 2400 km. 

1. Great Himalayas or HIMADRI
They are the most continuous upper layer of the Himalayas with an average altitude of 6000 m containing all the prominent Himalayan peaks. This range is snow bound all year round and a number of rivers originate from the glaciers in this range. 

2. Lesser Himalayas or HIMACHAL
They are the second layer of the Himalayas with an average altitude of 3700-4500 m and width of 50 km. Major ranges are Pir Panjal, Dhaula Dhar and Mahabharat. 

3. Outer most Himalayas or SHIWALIKS
Average width of 10-50 km and average altitude of 900-1100 m. 

Answer 2

The Himalayas are the result of tectonic plate motions that collided India into Tibet.

Because of the great amount of tectonic motion still occurring at the site, the Himalayas have a proportionally high number of earthquakes and tremors.

The Himalayas are one of the youngest mountain ranges on the planet.

The range affects air and water circulation systems, impacting the weather conditions in the region.

The Himalayas cover approximately 75% of Nepal.

Serving as a natural barrier for tens of thousands of years, the range prevented early interactions between the people of India and the people of China and Mongolia.

Mt. Everest was named after Colonel Sir George Everest, a British surveyor who was based in India during the early-to-mid-nineteenth century.
