Chapter Summary
Students should be able to identify and list the six major physiographic divisions of India: The Himalayan Mountains, The Northern Plains, The Peninsular Plateau, The Indian Desert, The Coastal Plains, and The Islands, and understand their basic geological differences (e.g., age and stability).
Students must differentiate between the three parallel ranges of the Himalayas based on their characteristics: the Himadri (Great or Inner Himalayas), the Himachal (Lesser Himalayas), and the Shiwaliks. This includes understanding their relative altitudes, composition, and key features like peaks, valleys, and Duns.
Students should understand how the Himalayas are divided into regional sections from west to east based on the river valleys that demarcate them. This includes identifying the Punjab, Kumaon, Nepal, and Assam Himalayas.
Students should be able to locate and describe the Purvachal or Eastern Hills, understanding that they are the southward bend of the Himalayas along India's eastern border. They should also be able to name key hill ranges like the Patkai, Naga, and Mizo hills.
Students should understand that the Northern Plains are fertile lands formed by the interplay and alluvial deposits of the Indus, Ganga, and Brahmaputra river systems. They should also recognize the major sections: Punjab Plains, Ganga Plain, and Brahmaputra Plain.
Students must be able to distinguish between the four distinct relief zones of the Northern Plains from north to south: Bhabar (pebbles, disappearing streams), Terai (swampy, re-emerging streams), Bhangar (older alluvium, terrace-like), and Khadar (newer alluvium, floodplains).
Students should understand that the Peninsular Plateau is an ancient tableland made of crystalline rocks from the Gondwana landmass. They must identify its two broad divisions: the Central Highlands (north of Narmada) and the Deccan Plateau (south of Narmada).
Students should be able to describe the key features of the Central Highlands (bounded by Aravalis and Vindhyan range, eastward extensions) and the Deccan Plateau (triangular shape, bounded by Satpura range, slope from west to east).
