Detailed Summary

This section elaborates on the diverse physical features of India, emphasizing its varied terrain, which reflects major physiographic divisions. India is characterized by:

  1. The Himalayan Mountains: These are geologically young and represent the loftiest mountain barrier in the world, running about 2,400 km from the Indus to the Brahmaputra. They consist of the Great Himalayas, Lesser Himalayas, and Shiwaliks, each possessing unique features such as high peaks, valleys, and glaciers.
  2. The Northern Plains: Formed by the river systems of the Indus, Ganga, and Brahmaputra, these plains are composed of fertile alluvial soil. They are critical for agriculture and are densely populated.
  3. The Peninsular Plateau: Comprised of old crystalline, igneous, and metamorphic rocks, this plateau includes significant features such as the Central Highlands and the Deccan Plateau, which are rich in minerals and biodiversity.
  4. The Indian Desert: An arid climate with low vegetation, this region is primarily located on the western side of the Aravalis, receiving minimal rainfall.
  5. The Coastal Plains and Islands: Stretching along the Arabian Sea and the Bay of Bengal, these plains are significant for fishing and trade and include coral islands like Lakshadweep and Andaman & Nicobar Islands.

Overall, the unique geographical features contribute to India's rich cultural and natural resources, illustrating a complex interaction between various physical landscapes.
