Ans.1:

a) Himadri: This is the northernmost hill range in the Himalayan mountains. It is also known as the Great or the Inner Himalayas. This is among one of the most continuous range in the world with an average elevation of 6,000 meters. The prominent peaks like Mount Everest form a part of this range. The core of this range is formed from granite and the folds are asymmetrical. This range is completely covered with snow and witnesses several glaciers.

b) Himachal: The range lying to the south of the Himadri is the Himachal range or the Lesser Himalayas. The average width of this range is 50 km and the elevation ranges between 3,700 and 4,500 meters. The Pir Panjal is the longest mountain range. Other prominent ranges include the Dhaula Dhar and the Mahabharat ranges. Some of the most famous hill stations also form a part of this range. For example, Kangra and Kullu Valley.

c) Shivalik: The Shiwaliks is the outermost range of the Himalayas. It is also known as the Lower Himalayas. The width of the range is between 10-50 km, and the elevation ranges between 900 and 1,100 meters. This range contains the sediments brought down by the perennial rivers originating in the Himadri. Various longitudinal valleys lying between the Himachal and the Shiwaliks, called the Duns are also present. Dehra Dun, Kotli Dun and Patli Dun are some of its examples.




d) Purvanchal: The Purvanchal mountains form the eastern-most boundary of the Himalayas. These mountains spread along the eastern boundary of India. These are made of sedimentary rocks, mostly sandstone. The important hills include the Patkai hills, the Naga hills, the Manipur hills and the Mizo hills.

Ques.2: What is the regional division of Himalayas? Explain.

Ans.2: Regionally, the Himalayas are divided into 4 types i.e. the Punjab Himalayas, Kumaon Himalayas, Nepal Himalayas, and the Assam Himalayas. These divisions are done in the direction from west to east. The Punjab Himalayas lie between the Indus and Satluj rivers. The Kumaon Himalayas are regionally known as Kashmir or Himachal Himalayas. The Nepal Himalayas lie between the Kali and Teesta rivers. The Assam Himalayas lie between the Teesta and Dihang rivers.

Ques.3: Which are the major divisions of the Northern Plains?

Ans.3: The Northern Plains are broadly divided into:

a) Punjab Plains: These plains are formed by the Indus river and its tributaries. Most of these plains lie within Pakistan. This plain is dominated by the doabs.

b) Ganga Plain: As the name suggests, these plains are formed by the tributaries of Ganda, namely Ghaggar and Teesta. It covers the states of Haryana, Delhi, U.P., Bihar, and partly Jharkhand.

c) Brahmaputra Plain: This plain lies in northeast India, particularly Assam. It Is formed by the river Brahmaputra.

Ques.4: What are corals?

Ans.4: Corals are colonies of short-Lived microscopic organisms. They are found in shallow, mud-free and warm waters. They secrete calcium carbonate which along with their skeletons helps in the formation of the coral reefs. The reefs are broadly of three different types: barrier reef, fringing reed, and atolls. For example, the Great Barrier Reef of Australia. Also, the circular-shaped or horse-shoe shaped reefs are known as atolls.

Ques.5: Write a short note on the Coastal Plains of India.

Ans.5: The coastal plains are one of the major physiographic divisions of India. They are narrow coastal strips, running along the Arabian Sea in the west and Bay of Bengal in the east. The western coastal plains lie between the Western Ghats and the Arabian Sea. The northern part of these plains is known as the Konkan coast. The central stretch is the Kannad plain, and the southernmost plain is called the Malabar Coast. The eastern coastal plains lie between the Eastern Ghats and the Bay of Bengal. The northern part is known as the Northern Circar and the southern part is called the Coromandel coast. These plains are wider and pressed flat. All the rivers flowing into the Bay of Bengal form deltas on this plain. Chilika lake is one of the most important lakes found in this plain.

Class 9 Geography Chapter 2 Extra Questions and Answers – Long Answer Type Questions: 4-6 Marks

Ques.1: Discuss the importance of the Himalayan mountains as a major physiographic division of India.

Ans.1: The Himalayas are a major physiographic division of India. Its importance can be gauged from the following reasons:

a) The Himalayas serve as the climatic barriers for India. They block the cold winds coming from Siberia, thereby protecting the country from an inhospitable cold climate. They also help by deflecting the rain-bearing winds coming from the Bay of Bengal, thereby causing rains on the Northern Plains.

b) They separate India from the India subcontinent. They also provide effective protection against any infiltrations.

c) Majority of the perennial rivers of India originate from these mountains. These rivers provide a year-round supply of water and are also a source of hydel power. These rivers also have some of the species of animals exclusive to India. For example, the Gangetic dolphin.

d) The Himalayas also have some of the richest green and dense forests housings which are great for flora and fauna.

e) Some of the most beautiful tourist destinations in India are also a part of the Himalayan ranges. For example, Kangra in Himachal Pradesh, Kullu Valley in Kashmir, Darjeeling in West Bengal, etc.

Ques.2: Discuss the importance of the Northern Plains.

Ans.2: The Northern Plains are one of the most significant physiographic features of India. They are important for the following reasons:

a) The Northern Plains are formed by the fertile alluvial deposits brought down by the rivers. This makes the soil in the region extremely fertile, making is highly suitable for cultivation.

b) Most of the grain production of India comes from this region. Crops like wheat, rice, sugarcane, etc. are grown in this region. Hence, this region is also known as the ‘granary of India’.

c) This region also receives sufficient rainfall and is drained by perennial rivers, thereby ensuring year-round supply for water.

d) As the region is flat and levelled, wells, canals, and tube wells can be easily built.

e) Being the most fertile region in the country and highly suitable for cultivation, this region supports a high population. The states falling in this region, like Bihar, Uttar Pradesh, and West Bengal have highest population densities among other states in the country.




Ques.3: Discuss the main features of the Peninsular Plateau.

Ans.3: The main features of the Peninsular Plateau include:

a) The Peninsular Plateau is made up of crystalline igneous and metamorphic rocks. This is among the oldest landmasses of earth.

b) The plateau is broadly divided into two parts: Central Highlands and the Deccan Plateau.

c) The Central Highlands lie to the north of the Narmada river. The mountain ranges of Vindhyan and Aravalli form the northern and northwestern boundary of the Central Highlands respectively. The rivers of the Chambal, the Sind, the Betwa and the Ken drain this region, flowing from southwest to northeast. The eastward extensions of this plateau are locally known as the Bundelkhand and Baghelkhand. The Chota Nagpur plateau is its even further extension.

d) The Deccan plateau forms the southern extension of the Peninsular Plateau. It is triangular. The Satpura range lies at its north, and the Kaimur and Maikal range in the east. The Deccan Plateau extends to  Meghalaya, Karbi-Anglong, and North Cachar Hills in the East.

e) The Western and Eastern Ghats form an important part of the Peninsular plateau. The Western Ghats are continuous and the Eastern Ghats are discontinuous by nature. The average elevation of the Western Ghats is 900-1,600 meters and that of the Eastern Ghats is 600 meters.

f) A large part of the Peninsular is made up of the black soils which are of volcanic origin. This region is also popularly known as the Deccan Trap.
