The altitudinal variations are greater in the eastern half than those in the western half.

B. Division: 
The Himalaya consists of three parallel ranges in its longitudinal extent 
(i) Great or Inner Himalayas or the Himadri: It is the most continuous range with an average height of 6,000 metres. It contains all prominent Himalayan peaks. The core of this part of Himalayas is composed of granite. The folds of the Great Himalayas are asymmetrical in nature. It is perennially snow bound, and a number of glaciers descend from this
range.

(ii) Lesser Himalaya:

Question 3. 
Describe about the Peninsular Plateau.
Or
State the main features of the peninsular plateau.
Answer: 
Following are the main features of the peninsular plateau 
A. Location, size and structure: 
The peninsular plateau lies to the south of the northern plain. The Peninsular plateau is a tableland composed of the old crystalline, igneous and metamorphic rocks. This is the oldest landmass. It was formed due to the breaking and drifting of the Gondwana land. The plateau has broad and shallow valleys and rounded hills.

B. Main division- Peninsular Plateau can be divided into two parts :
(i) Central Highlands :
The part of the Peninsular plateau lying to the north of the Narmada river,is known as the Central Highlands. It includes Malwa Plateau, Bundelkhand Plateau and Chota Nagpur Plateau. Aravali range and Vindhyan range are the main mountain ranges of this part. The main rivers of this region are the Chambal, the Sind, the Betwa and the Ken which flows from southwest towards northeast.

(ii) Deccan Plateau: 
The shape of Deccan Plateau is triangular. It lies to the south of the river Narmada. This part of the peninsular plateau is very large. Main hills and ranges : In the north, there is Satpura range on its broad base. Mahadev, the Kaimur hills and the Maikal range are other main ranges. An extension of the Plateau can be seen in the northeast, locally known as the Meghalaya, Karbi-Anglong Plateau and North Cachar Hills. In this part, three important ranges from west to east are Garo, Khasi and Jaintia. 

Major rivers and hills: 
Mahanadi, Godavari, Krishna, Kaveri, Tapti etc. are the prominent rivers of this region. The slope of the Deccan plateau is towards the east, therefore the major rivers of this region such as Mahanadi, Godavari, Krishna, Kaveri etc flows in east and fall in Bay of Bengal, only Narmada and Tapti fall in Arabian sea in west.

C. Ghat: 
The Western Ghats and the Eastern Ghats mark the western and the eastern edges of the Deccan Plateau respectively.
(i) Western Ghat : 
The western edge of the Deccan plateau is known as the Western Ghats. Western Ghats are continuous and can be crossed through passes only. Their average elevation is 900- 1600 metres. The Western Ghats cause orographic rain. This rain occurs due to the rise of moist winds to rise along the western slope of the ghat. The height of the Western Ghats progressively increases from north to south. Anai Mudi (2,695 metres) and Doda Betta (2,637 metres) are two main highest peak in this region.

(ii) Eastern Ghat: 
The Eastern Ghats are located on the eastern edge of the Deccan plateau. Average elevation of Eastern Ghat is 600 meters. The Eastern Ghats stretch from the Mahanadi Valley to the Nilgiri in the south. The Eastern Ghats are discontinuous and irregular and dissected by rivers draining into the Bay of Bengal. Mahendragiri (1,501 metres) is
the highest peak in the Eastern Ghats. Shevroy Hills and the Javadi Hills are located to the southeast of the Eastern Ghats.

D. Rich soil: 
Peninsular Plateau contains rich black soil made up of lava. This is also known as Decean Trap.
E. Rich in minerals :
 Igneous rocks are found in the peninsular plateau. Being made from the oldest rocks, it has rich mineral deposits.

Question 4. 
Describe in detail about Indian coastal plain.
Answer: 
The coastal plains of different widths are located on either side of the peninsular plateau in the south of India. These plains can be divided in to two parts

(i) Konkan Coast : 
The northern part of the coast is called the Konkan (Mumbai - Goa) coast.

(ii) Kannad Plain : 
The central stretch is called the Kannad Plain.

(iii) Malabar coast: 
Southern stretch is called Malabar coast. Main Rivers- Rivers such as Narmada, Tapti and Mandovi etc. flows in western coastal plain. Main Port - Kandla, Mumbai, Mormugoa, Cochin and Mangalore etc. are the major port of this region.

B. Eastern Coastal Plain : 
The plains along the Bay of Bengal are wide and level.This is wider and leveled than the western coastal plain. This can be divided in to two parts

(i) Northern Circar : 
Northern part of the coast is known as ‘Northern . Circar’.

(ii) Coromandel Coast: 
Southern part of eastern coastal plain is known as ‘Coromandel Coast’.
Main Rivers : 
zahanadi, Godavari, Krishna and Kaveri are the main rivers which flows in eastern coastal plain. These rivers have formed extensive delta on this coast. Chilika Lake, located to the south of the ‘ Mahanadi delta in Orissa, is the largest saltwater lake in India.
