Question

Answer 1

Physical features of India may be divided into four physiographic units.They are  1 Himalayas-The Himalayas are home to many of the world’s highest mountains. Famous peaks include Everest, Karakoram (K2), Kailash, Kanchenjunga, Nanga Parbat, Annapurna, and Manaslu. The Himalayas are the third largest deposit of ice and snow in the world, after Antarctica and the Arctic. There are approximately 15,000 glaciers located throughout the range. At 48 miles (72 km) in length, the Himalayan Siachen glacier is the largest glacier outside the poles.

2 north Indian plain-The Gangetic Plains is the large space of level land that is made by the Ganges River in the northern parts of India and the border surrounding areas of the Himalayas. It is an important part of the countries of India, Nepal, and Bangladesh. Its space of about 700,000 square kilometers or 270,000 square miles is the home of about 1 billion persons (about one in every seven persons alive today).

Its western edge is the Thar Desert; its northern edge is the Himalaya Mountains, the highest mountains on Earth; its eastern edge is the Ganges Delta of Bangladesh, the largest River delta in the world; and its southern edge is made by the Vindhya and Satpura Mountains and Chota Nagpur Plateau of middle India.

3 Deccan Plateau-The Deccan Plateau is a large plateau in India which covers most of the southern part of the country. It is between three mountain ranges and extends over eight Indian states; in particular, the states of Telangana, Maharashtra, Andhra Pradesh, Karnataka, Kerala and Tamil Nadu are on this plateau.

4 coastal plains 

5 great Indian desert-

6 islands-There are a number of small and large islands some of which are of volcanic origin while some are of coral origin.

i. Lakshadweep islands in the Arabian Sea are a group of 36 coral islands. They are located off the coast of Kerala. These islands are mostly flat and hardly a few meters above sea level.

ii. Andaman and Nicobar Islands lie in the Bay of Bengal. They are a group of 324 islands which are volcanic in nature. The Andaman Islands are separated from the Nicobar Islands by the ten-degree channel. They are mostly rugged mountainous hills and considered submerged part of Arakanyoma fold belt.
