Answer: (a) The major physical divisions of India are:

  • The Himalayas: The Himalayas means the abode of the snow. The Himalayan mountains are divided into three main parallel ranges- The northernmost range is the Great Himalaya or Himadri; Middle Himalaya or Himachal lies to the south of Himadri, and the Shiwalik is the southernmost range.
  • The Northern Indian Plains: The Northern Plains lie to the south of the Himalayas. They are generally level and flat and are extremely fertile due to the alluvial deposits laid down by the rivers - the Indus, the Ganga, the Brahmaputra, and their tributaries. These river plains are good for cultivation. That's why there is the high concentration of population in these plains.
  • The Great Indian Desert: The Great Indian Desert is located in the western part of India. It is a dry, hot and sandy stretch of land. Since it receives very little rainfall, it has very little vegetation.
  • The Peninsular Plateau: The Peninsular Plateau lies to the south of the Northern Plains. It is triangular in shape. This is a region with numerous hill ranges and valleys. These ranges are Aravali hills, the Vindhyas, and the Satpuras. The rivers the Narmada and Tapi flow through these ranges. The plateau is rich in minerals like coal and iron-ore.
  • The Coastal Plains: Both to the east and west of the Peninsular Plateau lie the Coastal Plains. The western Coastal plains are very narrow and the eastern Coastal plains are much broader. There are a number of east flowing rivers that drain into the Bay of Bengal,e.g.- Mahanadi, Godavari, Krishna, and Kaveri.
  • The Islands: Two groups of islands also form part of India. They are- Lakshadweep Islands which lie in the Arabian Sea and the Andaman and the Nicobar Islands which lie in the Bay of Bengal.
  1. India shares its land boundaries with Pakistan, Afghanistan, China, Nepal, Bhutan, Bangladesh, and Myanmar.
  2. Narmada and Tapi are the two major rivers that fall into the Arabian Sea.
  3. The Sunderban delta is formed by the Ganga and the Brahmaputra.
  4. There are 29 States and 7 Union Territories in India. Punjab and Haryana are the states that have a common Capital (Chandigarh).
  5. The Northern Indian plains have been formed by the alluvial deposits laid down by the rivers - the Indus, the Ganga, the Brahmaputra and their tributaries. These river plains provide fertile land for cultivation and produce most of our country's food grains. This is why a large number of people live in the Northern Plains.
  6. Lakshadweep Islands are the smaller group of islands in the Arabian Sea. Many of these islands are formed by coral polyps. Corals are skeletons of tiny marine animals called polyps. When they die, their skeletal remains accumulated on the seabed, which grows higher and higher to form coral islands. Hence, Lakshadweep Islands are known as coral islands.
