-Himalaya is a mountain system, which separates the Indian subcontinent from Central Asia and Tibet. This mountain system is mainly composed of the Tan Parallel Ranges the Great Himalayas, the Central Himalayas and the Shivalik which is about 2400 km from west to east in the shape of an arc. Spans a length of. The rise of this arc is towards the south, ie towards the plains of northern India and the center towards the plateau of Tibet. Apart from these three categories, the fourth and most northern category is called the Pura Himalaya Main or Trans Himalaya. Which includes Karakoram and Kailash ranges. Most of the high mountain peaks of the world are located in the Himalayas. The Himalayan peaks are among the 100 highest peaks in the world. Mount Everest, the highest peak in the world, is a peak in the Himalayas. The Himalayas have more than 100 mountain peaks, which are over 7200 meters high.
The Great Himalayas, also called Himadri, is the highest range of the Himalayas. Igneous rocks are found in its core, which is in the form of rocks called granite and gabbro. There is an expansion of sedimentary rocks on the flanks and peaks. The Zanskar category of Kashmir is also considered part of this. The Great Himalayas have a sudden emergence like a wall north of the miniature Himalayas. The main central region (MCT) separates the Great Himalayas and the Small Himalayas from each other. The width of the Great Himalayas is about 25 km. And the average height is 6100 m. is. Almost all the high peaks of the Himalayas [[Everest, Kanchenjunga, Nanga (Naga) Mountains, Gasherbrum, Manahalu, Dhaulagiri, Annapurna, Gosainath, Cho-Q, Kamet, Badrinath, Nanda Devi, etc.) are in it. The Great Himalayas are composed of rock-cut, igneous or metamorphic rocks (granite, fine and fine). The base of the Himalayas is formed from the rocks of the Archean. Many places
But due to excessive thrust, old rocks are found lying on top of relatively new rocks. The Great Himalayas are almost an enclosed range. this
The range consists of very few passes, which are formed by antecedent rivers. Rainfall is relatively less in the Great Himalayas than in the Small Himalayas and Shivalik. It has high activity of physical weathering. However, it has lower erosion levels than the miniature Himalayas and Shivalik. Due to its high altitude, the forest area in it is quite low.
