Summary of "Physical features of India Part 1"
The video discusses the physical features of India, focusing on its major geographical formations, particularly the Himalayan Mountains and their subdivisions. The key points and scientific concepts presented include:
Major Physical Features of India:
- Himalayan Mountains:
- Outer or Sub-Himalayas (Shivalik Range):
- Southernmost and geologically youngest; extends from Arunachal Pradesh through Bhutan to West Bengal.
- Width: 10 to 50 kilometers; altitude: 900 to 1100 meters.
- Notable valleys: Dunes like Tahereh, Courtley, and Partly Boom.
- Lesser or Himachal Himalayas:
- Located south of the Great Himalayas; altitude: 3,700 to 4,500 meters; average width: 50 kilometers.
- Important ranges include:
- Pire Panjal Range: Largest sub-range; elevation: 1,400 to 4,100 meters.
- Solid Hard Range and Mahabharat Range.
- Key valleys: Kashmir, Kangra, and Kulu valleys.
- Great Himalayas (Hema 3):
- Most continuous and loftiest range; peaks exceed 8,000 meters; significant source of glaciers.
- Notable for deep gorges formed by rivers.
- Trans-Himalayas:
- About 40 kilometers wide and 965 kilometers long; includes the Karakoram, Ladakh, and Kailash ranges.
- Karakoram Range: Home to K2, the second highest peak in the world.
- Ladakh Range: High-altitude plateau; described as a cold desert.
- Outer or Sub-Himalayas (Shivalik Range):
Regional Divisions of the Himalayas:
- Western Himalayas: Extends from the Indus River to the Kali River; includes Kashmir, Himachal, Punjab, and Kumaon Himalayas.
- Central Himalayas: Stretches between the Kali and Teesta rivers; largely covered by Nepal.
- Eastern Himalayas: Between the Teesta and Brahmaputra rivers; includes Arunachal Pradesh.
Associated Mountain Ranges:
- Purvanchal Hills: Running north-south along the Myanmar border, formed due to the eastward movement of the Indo-Australian plate.
- Notable hills include:
- But Coy Hills (Arunachal Pradesh)
- Naga Hills (Nagas)
- Manipur Hills (Manipur)
- Lushai Hills (Mizoram)
- Highest peak of Naga Hills: Sara Mata Peak (3,826 meters).
- Notable hills include:
