Study Notes

Physical Features of India

  • India has a diverse range of landforms such as mountains, plains, deserts, plateaus, and islands.
  • The Himalayan Mountains are young, fold mountains running west to east, from the Indus to the Brahmaputra. They represent the world's most rugged mountain barriers.
  • The Himalayas have three parallel ranges: the Great Himalayas (Himadri), the Lesser Himalayas (Himachal), and the Shiwaliks.
  • The Great Himalayas are the loftiest, with an average height of 6,000 meters.
  • The Northern Plains are formed from alluvial deposits of the Indus, Ganga, and Brahmaputra rivers and their tributaries over millions of years.
  • The Northern Plains are around 7 lakh sq km and are densely populated with rich soil and favorable climate.
  • The Peninsular Plateau is one of the oldest landmasses on earth, composed of igneous and metamorphic rocks.
  • The Peninsular Plateau has two main divisions: the Central Highlands and the Deccan Plateau.
  • The Western Ghats and Eastern Ghats mark the western and eastern edges of the Deccan Plateau, respectively. The Western Ghats are higher than the Eastern Ghats.
  • The Western Ghats are crucial for the orographic rainfall.
  • The Indian Desert, located in western Rajasthan, is an undulating sandy plain with very low rainfall.
  • The Coastal Plains are narrow strips along the Arabian Sea and Bay of Bengal, formed by the deposition of sediments from rivers.
  • The islands of India include the Andaman and Nicobar Islands, and the Lakshadweep Islands. The Andaman and Nicobar Islands are larger than the Lakshadweep Islands.
  • The Lakshadweep Islands are composed of small coral islands.
  • The Himalayas, geologically young, have high peaks and deep valleys that are formed of unconsolidated sediments brought down by rivers from the main ranges.
  • The Himalayas have diverse longitudinal and regional divisions.
  • The Northern Plains are a flat, fertile area formed by alluvial deposits from rivers.
