Mention the significance of each physical division of India.
Our country's physical features have been divided into five broad forms on the basis of topography. Because of diversity, they have a distinct geographical identity. Each division complements the other and is dependent on it. This significance can be understood with the following points:
(1) Northern mountains: The high Himalayan mountains have acted as physical barriers to intruders in the past. They protect us from the cold Siberian winds flowing in from the north. They play a major role in the distribution of rainfall and are a source of the perennial rivers.
(2) Northern plains: The Indo-Gangetic Plains are very fertile due to the deposition of alluvium by the rivers. Hence, this region is considered very good for agriculture and is also called the food bowl of India.
(3) Peninsular plateau: This region is very rich in minerals. It comprises black soil, which is used for growing cotton, sugarcane, etc. It also has a great faunal and floral diversity.
(4) Coastal plains: They house all the major ports and harbours. They are also known for their scenic beauty, which includes a large number of estuaries, lagoons and backwaters.
(5) Island groups: Both the Andaman and Nicobar Islands and Lakshadweep are located in the critical areas of trade. These islands have extensive floral and fauna diversity. They are also known for their scenic beauty.
