About India: Physiographic Divisions & Rock Systems

This quiz is meant for students preparing for the IAS examination and other competitive tests, and for anyone who wants a wide-ranging survey of India's physiographic divisions and rock systems. It begins with the Himalayas -- their formation, the three parallel ranges of Himadri, Himachal and Shiwalik, the regional divisions from Punjab to Assam, the syntaxial bends, the Karakoram and Trans-Himalaya, and major peaks and passes. It then covers the Northern Plains -- their formation as a foredeep, the Bhabar, Terai, Bhangar and Khadar belts, the Punjab, Ganga and Brahmaputra plains, and features such as doabs and the Sundarbans delta. A third section covers the Peninsular Plateau -- its Gondwana origin, the Deccan Traps and black soil, the Central Highlands, the Aravalli, Vindhya and Satpura ranges, the Western and Eastern Ghats, and the Chotanagpur and Meghalaya plateaus. A fourth section covers India's coastal plains and islands -- the Konkan, Malabar, Coromandel and Northern Circars coasts, the Andaman and Nicobar and Lakshadweep islands, and major lagoons and gulfs. It closes with the geological rock systems of India -- the Archean, Purana, Dravidian and Aryan groups, the Dharwar, Cuddapah, Vindhyan and Gondwana systems, and their links to India's mineral wealth. When complete it will have one hundred and fifteen carefully checked questions, arranged in five packs of twenty-three.

Every question has four options, and the correct option can be in any position. After each question there is a detailed explanation of more than five lines, in simple Indian English that a school student can follow, giving the important names, terms and the points that examiners like to test.

Every fact has been checked against standard reference material on the physical geography and geology of India.
