Answer :
Himalayan Region Peninsular Plateau
It is formed due to the collision of the Indo-Australian and Eurasian plates. It is formed due to the breaking and drifting of the Gondwana land.
It consists of the loftiest mountains and deep valleys It consists of broad and shallow valleys and rounded hills.
It is formed at the edge of the Indo-Gangetic plain. It is formed at the edge of the Deccan Plateau.
The Himalayan region contains only a few minerals. The Peninsular Plateau is the storehouse of the minerals.
The rivers that originate from the Himalayas are perennial The rivers that originate from plateau are seasonal in nature.

Question 5:Give an account of the Northern Plains of India.

Answer :The northern plain has been formed by three major river systems, namely — the Indus, the Ganga and the Brahmaputra along with their tributaries. This plain is formed of alluvial soil. The deposition of alluvium in a vast basin lying at the foothills of the Himalaya over millions of years, formed this fertile plain. It spreads over an area of 7 lakh sq. km. The plain being about 2400 km long and 240 to 320 km broad, is a densely populated physiographic division. With a rich soil cover combined with adequate water supply and favourable climate it is agriculturally a productive part of India.

Question 6:Write short notes on the following.

(i) The Indian Desert

Answer :The Indian desert lies towards the western margins of the Aravali Hills. It is an undulating sandy plain covered with sand dunes. This region receives very low rainfall below 150 mm per year. It has arid climate with low vegetation cover. Streams appear during the rainy season. But they disappear very soon into the sand as they do not have enough water to reach the sea. Luni is the only large river in this region.

(ii) The Central Highlands

Answer :The part of the Peninsular plateau lying to the north of the Narmada river, covering a major area of the Malwa plateau, is known as the Central Highlands. The Vindhyan range is bounded by the Satpura range on the south and the Aravali on the northwest. The further westward extension gradually merges with the sandy and rocky desert of Rajasthan. The rivers that flows in this region are Chambal, the Sind, the Betwa and the Ken from southwest to northeast, thus indicating the slope. The Central Highlands are wider in the west but narrower in the east. The eastward extensions of this plateau are locally known as the Bundelkhand and Baghelkhand.

(iii) The Island groups of India

Answer :The islands groups of India have two major islands: The Lakshadweep islands and the Andaman and Nicobar Islands group.

The Lakshadweep Island group lying close to the Malabar coast of Kerala. This group of islands is composed of small coral islands. Earlier they were known as Laccadive, Minicoy and Amindive. In 1973, these were named as Lakshadweep. It covers small area of 32 sq km. Kavaratti island is the administrative headquarters of Lakshadweep. This island group has great diversity of flora and fauna. The Pitti island, which is uninhabited, has a bird sanctuary.

The elongated chain of islands located in the Bay of Bengal extending from north to south are Andaman and Nicobar Islands. They are bigger in size and are more numerous and scattered. The entire group of islands is divided into two broad categories – The Andaman in the north and the Nicobar in the south. It is believed that these islands are an elevated portion of submarine mountains. These island groups are of great strategic importance for the country. There is great diversity of flora and fauna in this group of islands too. These islands lie close to equator and experience equatorial climate and has thick forest cover.
