Q18. Read the given Passage carefully and answer the questions that follow: 3
The study of every subject is done according to some approach. The major approaches to studying geography have been (i) Systematic and (ii) Regional. The systematic geography approach is the same as that of general geography. This approach was introduced by Alexander Von Humboldt, a German geographer (1769 – 1859) while the regional geography approach was developed by another German geographer and a contemporary of Humboldt, Karl Ritter (1779 – 1859). In the systematic approach, a phenomenon is studied the world over as a whole, and then the identification of typologies or spatial patterns is done.
For example, if one is interested in studying about natural vegetation, the study will be done at the world level as a first step. The typologies such as equatorial rainforests or softwood conical forests or monsoon forests, etc. will be identified, discussed and delimited. In the regional approach, the world is divided into regions at different hierarchical levels, and then all the geographical phenomena in a particular region are studied. These regions may be natural, political or designated regions. The phenomena in a region are studied in a holistic manner searching for unity in diversity.
a. What is geography?
b. Which geographical approach is the same as that of general geography?
c. In the regional approach, the world is divided into regions at different hierarchical levels. True/false.
Ans:
a. Geography is an interdisciplinary subject of study.

Question numbers 24 to 28 are Long Answer Type Questions.
Q24. Explain with the help of a diagram the interior of the earth. 5
Ans: The structure of the earth can be divided into three parts:
(i) Crust
(ii) Mantle
(ii) Core
(i) Crust: It is the outermost solid part of the earth. It is brittle in nature. The oceanic crust is thinner (5 km) as compared to the continental crust (30 km). It is as much as 70 km thick in the Himalayan region. It is made up of heavier rocks having a density of 3 g/ cm3. The mean density of material in oceanic crust is 2.7 g/cm3.
(ii) Mantle: The portion of the interior beyond the crust is called the mantle. The mantle extends from Moho’s discontinuity to a depth of 2,900 km. The upper portion of the mantle is called the asthenosphere. The word ‘astheno’ means weak. It is considered to be extending up to 400 km. It is the main source of magma that finds its way to the surface during volcanic eruptions. It has a density higher than the crust’s (3.4 g/cm3). The crust and the uppermost part of the mantle are called lithosphere. Its thickness ranges from 10-200 km. The lower mantle extends beyond the asthenosphere. It is in a solid state.
(iii) Core: The core-mantle boundary is located at a depth of 2,900 km. The outer core is in a liquid state while the inner core is in a solid state. The density of material at the mantle-core boundary is around 5 g/cm3 and at the centre of the earth at 6,300 km, the density value is around 13 g/cm3. The core is made up of very heavy material mostly constituted by nickel and iron. It is sometimes referred to as the nife layer.
Q25. What do you know about the extension of our country? 5
Ans: India lies entirely in the Northern Hemisphere. The mainland of India extends from Kashmir in the North to Kanyakumari in the South and Arunachal Pradesh in the East to Gujarat in the West. India’s territorial limit further extends towards the sea up to 12 nautical miles (about 21.9 km) from the coast. Our southern boundary extends up to 6°45′ N latitude in the Bay of Bengal, the latitudinal and longitudinal extent of India, is roughly about 30 degrees, whereas the actual distance measured from North to South extremity is 3,214 km, and that from East to West is only 2,933 km. India has a total area of 32, 87,263 sq. km.
India’s land length is 15, 200 km and it has a coastline of 6,100 km on the mainland and 7, 517 km on the entire geographical coast of the mainland plus the island groups of Andaman and Nicobar located in the Bay of Bengal and Lakshadweep in the Arabian Sea. The mainland extends between latitudes 8°4’N (Kanyakumari, Cape Caverian) and 37°6’N (Indira Point, J&K) and longitudes 68°7’E (Dwarka, Gujarat) and 97°25’E (Arunachal Pradesh).
Q26. Name the important drainage patterns. 5
OR
Suppose you are travelling from Hardwar to Siliguri along the foothills of the Himalayas. Name the important rivers you will come across. Describe the characteristics of any one of them.
Ans: The important drainage patterns are:
OR
While travelling from Hardwar to Siliguri along the foothills of the Himalayas, we shall come across the Tons, Gomti, Saryu, Ramganga, Sharda, Gandak, Old Gandak, Kamla, Bagmati, Kosi and Ganga. Ganga rises in the Gangotri glacier near Gaumukh (3,900 m) in the Uttarkashi district of Uttaranchal. Here, it is known as the Bhagirathi. It cuts through the Central and the Lesser Himalayas in narrow gorges. At Devprayag, the Bhagirathi meets the Alaknanda; hereafter, it is known as the Ganga.
The Alaknanda has its source in the Satopanth glacier above Badrinath. The Alaknanda consists of the Dhauli and the Vishnu Ganga which meet at Joshimath or Vishnu Prayag. The other tributaries of Alaknanda such as the Pindar join it at Kama Prayag while Mandakini or Kali Ganga meets it at Rudra Prayag.
The Ganga enters the plains at Haridwar. From here, it flows first to the south, then to the southeast and east before splitting into two distributaries, namely the Bhagirathi and the Hugh. The river has a length of 2,525 km. It is shared by Uttarakhand (110 km) and Uttar Pradesh (1,450 km), Bihar (445 km) and West Bengal (520 km). The Ganga basin covers about 8.6 lakh sq. km area in India alone.
The Son is its major right bank tributary. The important left bank tributaries are the Ramganga, the Gomati, the Ghaghara, the Gandak, the Kosi and the Mahanada. The river finally discharges itself into the Bay of Bengal near Sagar Island.
Q27. What are the reasons for the decline of wildlife in India? 5
OR
It is important to conserve wildlife. Mention the initiatives taken in this direction.
Ans: Major reasons for the decline of wildlife in India are:
OR
In 1972, a comprehensive Wildlife Act was enacted, which provides the main legal framework for the conservation and protection of wildlife in India.
The two main objectives of the Act are; to provide protection to the endangered species listed in the schedule of the Act and to provide legal support to the conservation areas of the country classified as National parks, sanctuaries and closed areas. This Act has been comprehensively amended in 1991, making punishments more stringent and has also made provisions for the protection of specified plant species and conservation of endangered species of wild animals.
There are 103 National parks and 535 wildlife sanctuaries covering an area of 15.67 million hectares in the country. For the purpose of effective conservation of flora and fauna, special steps have been initiated by the Government of India in collaboration with UNESCO’s ‘Man and Biosphere Programme’. Special schemes like Project Tiger (1973) and Project Elephant (1992) have been launched to conserve these species and their habitat in a sustainable manner.
Project Tiger has been implemented since 1973. The main objective of the scheme is to ensure the maintenance of the viable population of tigers in India for scientific, aesthetic, cultural and ecological values.
Initially, Project Tiger was launched in nine tiger reserves, covering an area of 16,339 sq. km, which has now increased to 44 tiger reserves, encompassing 36,988.28 sq. km of tiger habitats distributed in 17 states. The tiger population in the country has registered an increase from 1,411 in 2006 to 1,706 in 2010
Q28. How is economic life in India affected by monsoon? 5
OR
How many distinct seasons are found in India as per the Indian Meteorological Department? Discuss the weather conditions associated with any one season in detail.
Ans:
OR
The distinct seasons found in India as per the Indian Meteorological Department are:
(i) The Cold Weather: Usually, the cold weather season sets in by mid-November in northern India. December and January are the coldest months in the northern plain. The mean daily temperature remains below 21°C cover most parts of northern India. The night temperature may be quite low, sometimes going below freezing points in Punjab and Rajasthan. The snowfall in the nearby Himalayan ranges creates a cold wave situation. There is hardly any seasonal change in the distribution pattern of the temperature in coastal areas because of the moderating influence of the sea and the proximity to the equator.
(ii) The Hot Weather: With the apparent northward movement of the sun towards the Tropic of Cancer in March, temperatures start rising in north India. April, May and June are the months of summer in north India. In most parts of India, temperatures recorded are between 30°-32°C. In March, the highest day temperature of about 38°C occurs in the Deccan Plateau while in April, temperatures ranging between 38°C and 43°C are found in Gujarat and Madhya Pradesh. The hot weather season in south India is mild and not as intense as found in north India.
(iii) The Southwest Monsoon: The rain in the southwest monsoon season begins rather abruptly. One result of the first rain is that it brings down the temperature substantially. This sudden onset of the moisture-laden winds associated with violent thunder and lightning is often termed as the “break” or “burst” of the monsoons. The monsoon may burst in the first week of June in the coastal areas of Kerala, Karnataka, Goa and Maharashtra while in the interior parts of the country, it may be delayed to the first week of July.
(iv) Season of Retreating Monsoon: The monsoon retreats from western Rajasthan by the first week of September. It withdraws from Rajasthan, Gujarat, Western Ganga Plain and the Central Highlands by the end of the month. The retreating southwest monsoon season is marked by clear skies and a rise in temperature. The land is still moist. Owing to the conditions of high temperature and humidity, the weather becomes rather oppressive. This is commonly known as the ‘October heat’.
