Island Groups of India
The island groups of India can be divided into 2 parts according to their location. They are:
The islands of the Bay of Bengal and The islands of the Arabian Sea.1. The islands of the Bay of BengalAmong the islands located in the Bay of Bengal the most important group is the Andaman and Nicobar group of islands. These islands are mainly the upper parts of mountains rising from the floor of the Bay. This is the reason why at different parts of the islands small hills can be seen distributed irregularly. They range in height between 400 to 500 meters e.g. Mount Harriet in the South Andamans. The highest peak of the Andaman group of islands in Saddle Peak (750 meters). The barren and Narcondam islands have volcanoes. Some islands are surrounded by coral reef. In the month of June 1991, the dormant volcano in the Barren islands suddenly erupted. It erupted again in January 1991, the dormant volcano in the Barren island suddenly erupted. It erupted again in January 1995. The volcano in the Narcondam island is still quiet so it s an extinct or dead volcano.
2. Islands of the Arabian SeaOff the Malabar coast of Kerala lay the islands of Amindivi, Lakshadweep and Minicoy. They lie in the Arabian Sea. These islands have been formed by deposits of millions of corals and so form coral islands. Thus the soil of these islands is also very fertile.
Importance of the islands: All these islands are very small in area so they have to depend on the mainland for various reasons. The islands in the Arabian Sea are closer to the mainland, so they are comparatively developed. The soil is very fertile in these islands of the Arabian Sea, so farming is productive causing higher density of population. On the other hand, the rocky land, dense forest, greater distance from the mainland etc. have caused the islands of the Bay of Bengal to be less developed. Their density of population is low. The forest in these islands has some good timber e.g. teak, mahogany, etc. Spices like cloves, cinnamon, cardamom, pepper, etc. are cultivated here.
Besides mainland, Indian Territory also extends into the Arabian Sea and the Bay of Bengal in the form of the Lakshwadeep and the Andaman and Nicobar Islands, respectively. India has a total of 615 islands of which 572 lie in the Bay of Bengal and the remaining 43 in the Arabian Sea. The Islands of India are usually divided into two parts (a) Islands close to the coast (b) Islands distant from the coast.
Lakshadweep Islands lying opposite to the coast of Kerala are small but numerous. They are the product of a very quiet work of the short lived microscopic species the coral polyps. They flourish only in shallow warm waters. Many islands are generally ring or horse-shoes shaped and are called atolls.
The Andaman Nicobar Islands on the other hand, are bigger in size and more numerous. They are located on a submerged hilly range. Some of them are of volcanic origin. The only active volcano of India is located on these Islands.
The Lakshadweep meaning a hundred thousand islands. These are scattered between 8°N-12°N and 71°E-74°E longitude. There are approximately 43 islands of which 11 are in habited. Minicoy is the longest with an area of 453 sq. km. The Andamans and Nicobars also known as the Bay islands are also a cluster of Islands stretched almost in a line.
Andaman Nicobar Islands consists about 572 islands itself. These are situated roughly between 6°N-14°N and 92°E, Out 572 islands of Andaman and Nicobar only 36 are inhabited. Some of the islands extend from 60 to 100 kms, forming a cluster south of the Andaman group.
They are fairly large and more numerous than the Lakshadweeps. Some of the islands are of volcanic origin. Barren Island is an active volano. The Lakshadweeps extend just to the north of the independent country known as the Maldives. The Islands of Andaman and Nicobar are remnants of the submerged mountain range, which was an extension of the Arakan Mountains of Myanmar and continued through the islands of Java and Sumatra in Indonesia.
Physiographic divisions of India described above are complementary to each other. The peninsular is the stable block which has provided the building material for the Northern Plains and the Mountains. The northern mountains are the major source of water, and gire the subcontinent for thousands of kilometres. This partially enclosed character of the subcontinent has helped in strengthening the forces of homogeneity of our people.
