a. The Great Indian Desert or the Thar Desert is located in western Rajasthan. It is a sandy plain receiving rainfall as low as 150mm in a year. THE vegetation cover in the region is extremely scarce. Some small streams appear during the rainy season but they quickly disappear into the sand. Luni is the only large river in this region. Barchan, crescent shaped sand dunes are prominent feature of the desert.
b.
The peninsular plateau is divided into two- the central highlands and the Deccan plateau.The part of the peninsular plateau lying to the north of the Narmada river is known as the Central highlands.The Vindhyan range is bounded by the central highlands on the south and the Aravalis on the northwest.The central highlands are wider in the west but narrower in the east.The further westward extension gradually merges with the sandy and rocky desert of Rajasthan.The flow of rivers draining this region,namely the Chambal,the Sind,the Betwa,and the Ken is from southwest to northeast,thus indicating a slope.The eastward extensions of this plateau are locally known as the Bundelkhand and the Baghelkhand.
c. India has two groups of islands. The Lakshadweep Islands lie in the Arabian Sea, to the southwest of the mainland. The Andaman and Nicobar Islands lie in the Bay of Bengal, to the southeast of the mainland.
Lakshadweep is composed of small coral islands, covering a small area of 32 square kilometres. Kavaratti Island is its administrative headquarters. The Andaman and Nicobar Islands are bigger in size and are more numerous and scattered. The entire group of islands is divided into Andaman (in the north) and Nicobar (in the south).
Both these island groups are rich in flora and fauna, and are of great strategic importance to the country.
