3. Himalayas….description Sedimentary rock Metamorphic rock The Himalaya are among the youngest mountain ranges on the planet and consist mostly of uplifted sedimentary and metamorphic rock. According to the modern theory of plate tectonics, their formation is a result of a continental collision or orogeny along the convergent boundary between the Indo-Australian Plate and the Eurasian Plate

4. The 6,000 kilometers plus journey of the India landmass (Indian Plate) before its collision with Asia (Eurasian Plate) about 40 to 50 million years ago.

5. The Himalayas are divided into three parallel. Ranges: The greater Himalayas……..himadri The lesser Himalayas…..himachal The outer Himalayas……shiwaliks Himalayas…..divisions

6. The greater Himalayas……himadri It is the most continuous range consisting of the loftiest peaks with an average height of 6,000 meters. It contains all the prominent Himalayan peaks. The folds of great Himalayas are asymmetrical in nature. The core of this part of Himalayas is composed of granite. It is perennially snow bound, and a number of glaciers descend from this range. granite

7. The lesser Himalayas……..himachal It is the most rugged mountain system, these ranges are mainly composed of highly compressed and altered rocks. The altitude varies between 3,700 and 4,500 meters and the average width is of 50 km. while the pir panjal range forms the longest and the most important range, the dhaula dhar and the mahabharat ranges are also prominent ones. This range consists of the famous valley of Kashmir, the kangranand kullu valley in himachal Pradesh. This region is well known for its hill station.

8. The outer Himalayas…..shiwaliks These extend over a width of 10-50 km and have an altitude varying between 900 and 1100 meters. These ranges are composed of unconsolidated sediments brought down by rivers from the main Himalayan range s located farther north. These valleys are covered with thick gravel and alluvium. The longitudinal valley lying between lesser Himalaya and the shiwaliks are known as duns. gravel Alluvium rock
