(vii) Delhi has a population density of 9,340 persons per sq. km. which is much higher than the national average of 325 persons per sq. km. Explain why.
(viii) Define cultivable waste. Give any one reason for its existence.
(ix) Name any two strategies adopted to usher in the second Green Revolution in India.
(x) India is richly endowed with a variety of minerals. State two reasons in support of this statement.
Answer 1:
(i) Indian Ocean is the only ocean in the world which has been named after a country (India), this is the biggest proof of the prominence enjoyed by India in early days when oceans were given their names. liven today India’s position in the Indian Ocean is paramount as :
(a) India stands at the head of the Indian Ocean at the very centre of the Eastern Hemisphere commanding trade routes running in all directions.
(b) India commands an important strategic position on the globe with respect to trade as well as social cultural interaction. Economically and culturally India had major contacts with outside world in the last two millennia via Indian Ocean, no other country has as a long a coast line on this ocean as India has.


(a) ‘B’ is Shivalik hills.
‘C’ is Plains of new fertile alluvial-Khadar.
‘D’ is Plains of older coarse nodules of alluvium-Bhangar.
(b) C is the sediment deposit which is new and fertile.


(iii) Many of the Himalayan rivers which existed even before the Himalayan ranges were uplifted. The gorges of the Indus, the Satluj, the Alakananda clearly indicate that these rivers are older than mountains. During the upliftment of Himalayas, their banks rose steeply while the beds went lower, thus cutting deep gorges in the Himalayas. Thus, the rivers of North India are typical examples of antecedent drainage.

(iv) Indo-Gangetic plain is a flat and featureless plain which has its own diversities of relief. Keeping their diversities in view, the plain can be divided in four divisions: The Bhabar, the Tarai, the Bhangar and the Khadar.

The Bhangar is an area which is composed of old alluvium and forms the alluvial terrace above the level of the flood plains. Bhangar area also has some striking differences in the local relief.

(a) One such difference is found in the deltaic region of Bengal, it has extensive laterite formation in the Bhangar known as “Barind.”.
(b) “Bhur” is another such difference found in upper Ganga-Yamuna doab. Bhur has been formed due to the weathering of soft fine grained topsoil, where only the coarse grained soil is left behind.

(v) Virgin Vegetation are often biodiversity hotspots because these areas are rich in plant and animal species.
The Nilgiris in Western Ghats and Gulf of Mannar in Tamil Nadu are best examples.

(vi) The arithmetic density of population is different from physiological density of population as :
(a) Arithmetic density is the ratio of total population to the total area of the country or a part thereof. For example, the total population of India according to 2001 census is 1028.7 million living on a total area of 3.17 million square kilometres (excluding the area of Jammu and Kashmir illegally occupied by Pakistan and China) thus, the arithmetic density of India, according to 2011 census is 372 persons/km2. The arithmetic density of population of India in 2001 is :
ISC Geography Question Paper 2012 Solved for Class 12 - 8
\frac { 1028.7 }{ 3.17 }
= 325 persons per
It is most simple and widely used all over the world but it is a ‘crude measure’.

(b) Physiological Density is different to Arithmetic density as physiological density is the ratio of total population to the cultivated area of the country. For example : The physiological density of India, according to 2011 census is 1594 persons/km2.
According to 2001 census, the total population of India is 1,02,87,37,436 and the total cultivated area in the country is 14(28,190 sq km, therefore, the physiolo-gical density is :
ISC Geography Question Paper 2012 Solved for Class 12 - 7
\frac { 1,02,87,37,436 }{ 14,28,190 }
= 720 person per sq km.
This is a very useful measure for an agricultural country like India.

(vii) According to 2011 census, Delhi’s population density is 11,297 persons per  km2. The high population density is mainly owing to the large-scale in migration that was taken place. Delhi, being the largest commercial center, attracts huge chunks of population from adjoining areas. Rapid growth and development of key industries such as IT, hotels, banking, media and tourism has absorbed the migrants resulting in high density.

(viii) Cultivable waste is the land available for cultivation but not used for cultivation for one reason or the other. This land has been abandoned for some reasons such as lack of water, salinity or alkalinity of soil, soil erosion, waterlogging, unfavourable physiographic position, human neglect or deficiencies occurred in soil due to the faulty agriculture practices.


(a) Micro-irrigation system.
(b) Organic farming.

(x) India is richly endowed with a variety of minerals and diverse geological formations. The following two points illustrate this :
(i) Development of Mining : India has huge population and mining can be an important activity to absorb large labour force. India needs to develop efficient technology to avoid waste and to work the mines economically.
(ii) Political Influence : Existence of mineral resources was one of the greatest factors responsible for emergence of imperialism and colonization.
