Geographical Diversity of India

  1. India has a rich geographical diversity, with mountains, plains, plateaus, deserts, coasts, and islands.

  2. The Himalayas in the north act as a natural barrier and are home to the world's highest peaks.

  3. The fertile Gangetic Plains support a large population through agriculture.

  4. The Thar Desert, the Peninsular Plateau, and the coastal regions show India's varied landscapes.

  5. This diversity influences India's climate, culture, biodiversity, and way of life.


The Himalayas

  1. The word ‘Himalaya’ is a combination of two Sanskrit words — hima, meaning ‘snow’, and ālaya, meaning ‘abode’ or ‘dwelling’ — thus, ‘abode of snow’.

  2. The Himalayas seem to touch the sky. 

  3. In fact, many of its peaks are over 8000 metres in height and are together called the ‘Eight Thousanders’. 

  4. This mountain range stretches across six countries in Asia: India, Nepal, Bhutan, China, Pakistan, and Afghanistan. 

  5. Himalayas are sometimes called the ‘Water Tower of Asia’. The Himalayas are also important to many cultures and belief systems.

  6. Gangotri Glacier  is one of the largest in the Indian Himalayas.

  7.  It is considered sacred and attracts many pilgrims. 

  8. Gaumukh is also a popular trekking destination.


Three Ranges of Himalaya

  1. The Himadri (the Greater Himalayas) are the highest and most rugged part of the range, home to towering peaks like Mount Everest and Kanchenjunga. Life here is tough, and there are not many human settlements.

  2. The Himachal (the Lower Himalayas) lie south of the Greater Himalayas and have a more moderate climate, allowing rich biodiversity and human habitation. Popular hill stations, such as Nainital (Uttarakhand), Darjeeling (West Bengal), Shimla (Himachal Pradesh), and Mussoorie (Uttarakhand), are located in this region.

3. The Shivalik Hills (the Outer Himalayas) form the outermost and lowest range, consisting of rolling hills and dense forests. These foothills are rich in wildlife, serving as a transition zone between the Himalayas and the Gangetic Plains (also called the Northern Plains).
