ISC Class 12 Geography Board Exam Question Paper with Solutions 2012

PART - I (Compulsory)

Answer all questions.

Question 1. [20 Marks]

(i) India's position in the Indian Ocean is paramount. Give two reasons to justify the given statement. [2 Marks]

Answer:
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. Even today India's position in the Indian Ocean is paramount as:
1. India stands at the head of the Indian Ocean at the very centre of the Eastern Hemisphere commanding trade routes running in all directions.
2. India commands an important strategic position on the globe with respect to trade as well as socio-cultural interaction. Economically and culturally India had major contacts with the outside world in the last two millennia via the Indian Ocean, and no other country has as long a coastline on this ocean as India has.

Teacher's Note:
a) Emphasize India's central location in the Eastern Hemisphere and its long coastline.
b) Students must mention both the strategic trade advantage and historical maritime links for full credit.

(ii) Study the cross-section given below which represents the basin of the Indo-Gangetic plain.
(a) Name the features B, C and D in the cross-section.
(b) Which layer of sediments among the above features is new and fertile. [2 Marks]

[Figure: Cross-section of the Indo-Gangetic plain showing A - Upper Himalayas, B - Shivalik hills, C - Plains of new fertile alluvial - Khadar, D - Plains of older coarse nodules of alluvium - Bhangar, and the Peninsula at the southern end.]

Answer:
(a) Feature B is Shivalik hills, Feature C is Plains of new fertile alluvial (Khadar), and Feature D is Plains of older coarse nodules of alluvium (Bhangar).
(b) C is the sediment deposit which is new and fertile.

Teacher's Note:
a) Khadar represents newer alluvium deposited annually by floods, making it extremely fertile.
b) Ensure students correctly distinguish between Khadar (C) and Bhangar (D) based on their relative positions and age of sediments.

(iii) The rivers of North India are Antecedent in nature. Explain with an example. [2 Marks]

Answer:
Many of the Himalayan rivers existed even before the Himalayan ranges were uplifted. The gorges of the Indus, the Satluj, and the Alaknanda clearly indicate that these rivers are older than the mountains. During the upliftment of the 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. For example, the river Indus or Brahmaputra.

Teacher's Note:
a) Explain that antecedent rivers maintained their course through tectonic uplift by vertical erosion.
b) Students must provide at least one correct example like the Indus, Satluj, or Brahmaputra.

(iv) Differentiate between Barind and Bhur with reference to the Indus - Ganga - Brahmaputra Plain. [2 Marks]

Answer:
1. Barind: It is an extensive laterite formation found in the Bhangar (older alluvium) area, particularly in the deltaic region of Bengal.
2. Bhur: It is an undulating feature formed in the upper Ganga - Yamuna doab due to the weathering of soft fine-grained topsoil, leaving behind coarse-grained sandy soil.

Teacher's Note:
a) Both Barind and Bhur are regional micro - relief variations found within the plain.
b) Clearly mention the geographic location and specific characteristics of each to secure full marks.

(v) What is meant by virgin vegetation? Name any two regions in India where such vegetation occurs. [2 Marks]

Answer:
Virgin vegetation refers to the plant community which has grown naturally without human interference and has been left undisturbed by humans for a long time. These areas are often biodiversity hotspots rich in native plant and animal species.
Two regions in India where such vegetation occurs are:
1. The Nilgiris in the Western Ghats.
2. Gulf of Mannar in Tamil Nadu.

Teacher's Note:
a) Virgin vegetation is synonymous with natural or endemic vegetation untouched by human cultivation.
b) Accept other valid protected biodiversity regions such as parts of Andaman and Nicobar Islands or North-East India.

(vi) How is arithmetic density of population different from physiological density of population? [2 Marks]

Answer:
1. Arithmetic Density: It is the ratio of total population to the total geographical area of a country or region (Total Population / Total Area). It is a simple and crude measure.
2. Physiological Density: It is the ratio of total population to the total cultivated (net sown) area of the country (Total Population / Cultivated Area). It is a more meaningful measure for agricultural countries.

Teacher's Note:
a) Mention the formula for both terms to clearly show the difference in denominators (total area versus cultivated area).
b) Highlight that physiological density gives a clearer picture of population pressure on agricultural land.

(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. [2 Marks]

Answer:
The exceptionally high population density of Delhi is mainly owing to large-scale in-migration. Being the national capital and the largest commercial center, Delhi attracts huge chunks of population from adjoining rural and urban areas. Rapid growth and development of key industries such as IT, hotels, banking, media, and trade have absorbed millions of migrants, resulting in very high population concentration.

Teacher's Note:
a) Focus on economic opportunities, employment, and rural-to-urban migration as primary drivers.
b) Mentioning administrative status and commercial importance adds weight to the answer.

(viii) Define cultivable waste. Give any one reason for its existence. [2 Marks]

Answer:
Cultivable waste refers to land available for cultivation but left uncultivated for more than five consecutive agricultural years.
Reason for its existence: It has been abandoned due to limitations such as lack of water, salinity or alkalinity of soil, soil erosion, waterlogging, or human neglect.

Teacher's Note:
a) Ensure the time duration criteria or land-use category definition is clear.
b) Any valid physical or human constraint leading to land abandonment is acceptable as a reason.

(ix) Name any two strategies adopted to usher in the second Green Revolution in India. [2 Marks]

Answer:
1. Adoption of micro-irrigation systems (drip and sprinkler irrigation).
2. Promotion of organic farming and sustainable agricultural practices.

Teacher's Note:
a) The second Green Revolution focuses on ecological sustainability, water conservation, and high-value agriculture.
b) Other valid answers include soil health card schemes, biotechnology applications, and watershed management.

(x) India is richly endowed with a variety of minerals. State two reasons in support of this statement. [2 Marks]

(i) Identify the dotted region. Name the predominant rock that constitutes the region.
(ii) Label the mountain range shown as X and the rivers R₁, R₂ and R₃. [3 Marks]

[Figure: Map diagram of northwestern Peninsular Plateau showing dotted Malwa Plateau region, Aravali Range (X), Luni River, R₁ (Chambal), R₂ (Betwa), and R₃ (Yamuna).]

Answer:
(i) Dotted region is the Malwa Plateau region. Hard igneous rocks like basalt and granite are the predominant rocks that constitute it.
(ii) Mountain range X is the Aravali Range.
R₁ is River Chambal.
R₂ is River Betwa.
R₃ is River Yamuna.

Teacher's Note:
a) The Malwa plateau is largely formed of Malwa trap/basaltic lava flows and granitic rocks.
b) Students must carefully identify tributary river systems joining the Yamuna from the peninsular upland.

(b) The diagram given below shows the regimes (annual fluctuation in discharge) of two hypothetical rivers X and Y. [4 Marks]
(i) Identify which of the two rivers represent the regime of a peninsular river. Give a reason for your answer.
(ii) Name the peninsular river which is an exception to the general pattern. Why is it an exception?

[Figure: Line graph showing monthly discharge curves for two hypothetical rivers X and Y across months J to D]

Answer:
(i) River X represents the regime of a peninsular river because peninsular rivers are seasonal and rain-fed, showing high discharge during the monsoon months (June to November) and very low discharge in the dry summer months.
(ii) Narmada and Tapi are exceptions among peninsular rivers. They flow from east to west and drain into the Arabian Sea (Gulf of Khambhat) through rift valleys, unlike most other peninsular rivers which flow from west to east into the Bay of Bengal.

Teacher's Note:
a) Monsoon dependency dictates the sharp seasonal peak in peninsular river regimes.
b) Emphasize that Narmada and Tapi flow through rift valleys created by tectonic faulting, explaining their unusual westerly flow.

(c) (i) Why are deciduous forests of India considered economically important? [1 Mark]

Answer:
Deciduous forests are economically important because trees grow in pure stands or patches making commercial exploitation easier. They are less dense and easily accessible, and they provide valuable commercial timber such as teak, sal, shisham, sandalwood, and khair.

Teacher's Note:
a) Highlight the commercial utility and accessibility of tropical deciduous trees.
b) Mention specific valuable timber species like teak and sal.

(ii) Give two reasons to explain the decrease in forest cover in recent years. [2 Marks]

Answer:

2. Reckless clearing of forests for acquiring land for agriculture, industrial expansion, and infrastructure construction.

Teacher's Note:
a) Focus on anthropogenic pressures such as deforestation for agriculture and urban growth.
b) Keep points concise and directly linked to modern environmental challenges.

Question 4.

(a) Define population growth and population growth rate. [2 Marks]

Answer:
Population growth is the absolute change in the number of inhabitants of a particular area/country during a specific period, calculated as the difference between births and deaths (plus migration). Population growth rate is the change in population expressed as a percentage change per year over a given period of time.

Teacher's Note:
a) Distinguish clearly between absolute numerical increase (growth) and percentage increase (growth rate).
b) Ensure natural increase and net migration components are understood.

(b) Differentiate between crude literacy rate and literacy rate. [2 Marks]

Answer:
1. Crude Literacy Rate: It is calculated by dividing the total literate population by the total population of all age groups (including infants aged 0-6 years) and multiplying by 100.
2. Literacy Rate: It is calculated by dividing the literate population aged 7 years and above by the total population aged 7 years and above, multiplied by 100. It excludes children aged 0-6 years and is a more accurate measure of literacy.

Teacher's Note:
a) The key distinction is the denominator (total population versus population aged 7 and above).
b) Mentioning the age group 0-6 exclusion is vital for standard census definitions.

(c) How does census of India differentiate between statutory towns and census towns? [2 Marks]

Answer:
1. Statutory Towns: All places with a municipality, corporation, cantonment board, or notified town area committee declared by state law.
2. Census Towns: Non - statutory urban places that satisfy three demographic criteria: a minimum population of 5,000, at least 75 percent of the male working population engaged in non-agricultural pursuits, and a population density of at least 400 persons per sq. km.

Teacher's Note:
a) Statutory towns are defined by administrative governance status.
b) Census towns are defined purely based on demographic and economic thresholds.

(d) (i) Explain the term urban sprawl. Why is it considered to be a problem of urbanization? [2 Marks]

Answer:
Urban sprawl refers to the unchecked, uncoordinated spreading of a city and its suburbs into rural or undeveloped land at the outskirts. It is considered a problem because it leads to the loss of valuable agricultural land, increases commuting distances, promotes heavy dependence on private vehicles, and aggravates air pollution and infrastructure strain.

Teacher's Note:
a) Emphasize the rapid, unplanned outward expansion of urban peripheries.
b) Highlight environmental and infrastructural consequences like loss of farmland and traffic congestion.

(ii) What is a conurbation? Give two examples. [2 Marks]

Answer:
A conurbation is a large, densely populated urban area formed by the growth and coalescence (merging) of separate towns, cities, and their suburbs into a continuous urban landscape.
Examples: Greater Delhi urban agglomeration, Mumbai metropolitan region (or Kolkata urban agglomeration).

Teacher's Note:
a) The defining feature of a conurbation is the physical merging of formerly distinct urban centers.
b) Provide universally recognized metropolitan examples.

Question 5.

(a) What is rainwater harvesting? State two of its objectives. [3 Marks]

Answer:
Rainwater harvesting is the technique of collection, accumulation, and storage of rainwater for reuse on-site or recharging into underground aquifers before it runs off.
Two main objectives are:
1. To collect and store rainwater to meet the increasing domestic, agricultural, and industrial water demands during dry periods.
2. To prevent runoff losses and recharge groundwater tables, thereby raising the water table.

Teacher's Note:
a) Define rainwater harvesting clearly as capturing precipitation for direct use or artificial recharge.
b) Objectives must address water conservation and groundwater augmentation.

(b) How is agriculture responsible for reduction in the availability of surface and ground water? [2 Marks]

Answer:
1. Over-extraction of groundwater: Intensive irrigation through tube-wells leads to a drastic fall in the water table.
2. Pollution of water bodies: Indiscriminate use of chemical fertilizers, pesticides, and insecticides results in agricultural runoff that pollutes surface and groundwater sources.

Teacher's Note:
a) Cover both quantitative depletion (over-pumping) and qualitative degradation (chemical pollution).
b) Keep points direct and well-structured.

(c) What are the two categories of 'land not available for cultivation'? [2 Marks]

Answer:
The two categories of land not available for cultivation are:
1. Land put to non-agricultural uses (land occupied by buildings, roads, railways, factories, water bodies, etc.).
2. Barren and wasteland (hilly terrains, desert areas, ravines, and rocky tracts which cannot be brought under cultivation).

Teacher's Note:
a) Standard land-use classification divides uncultivable land into non-agricultural use and barren/wasteland.
b) Ensure accurate terminology as per official agricultural geography classifications.

(d) Give three reasons to explain the importance of irrigation in Indian agriculture. [3 Marks]

Answer:
1. Uncertainty and Irregularity of Rainfall: Monsoon rainfall in India is erratic, uneven, and unpredictable in onset and withdrawal, making artificial irrigation essential for crop survival.
2. Uneven Spatial Distribution: Rainfall is heavily concentrated in certain months (June to September) and regions, leaving arid and semi-arid regions dependent on irrigation.
3. Multiple Cropping and High-Yielding Varieties (HYV): Growing multiple crops per year and cultivating water-intensive HYV seeds and commercial crops (like sugarcane) require assured, frequent irrigation.

Teacher's Note:
a) Focus on climatic variability (monsoon uncertainty) and intensive farming requirements.
b) Mentioning commercial and HYV crop water demands provides complete justification.

Question 6.

(a) (i) What is the importance of Manganese in Iron and Steel Industry?
(ii) Name the state which is the leading producer of Manganese. Also, name any two areas in this state, where Manganese is mined. [3 Marks]

(c) (i) Give two reasons why the rivers of the northern mountains are more important for the generation of hydroelectric power in India.
(ii) Name the area with the highest power generating potential. [3 Marks]

Answer:
(i) 1. Northern Himalayan rivers are perennial as they are fed by both melting glaciers and monsoon rains, ensuring year-round power generation.
2. These rivers flow through steep, rugged mountainous terrain, providing ideal sites with great heads of water for generating hydroelectricity.
(ii) The North-Eastern part of the mountainous region (Brahmaputra river basin) has the highest hydroelectric power generating potential.

Teacher's Note:
a) Contrast perennial flow and topographic head with peninsular rivers.
b) The Brahmaputra basin holds India's highest hydel potential.

(d) State the chief characteristic of Japanese method of rice cultivation. Why is rice not cultivated in the northern parts of China? [2 Marks]

Answer:
Chief characteristic: Raising seedlings in nursery beds before transplanting them in rows into flooded fields, combined with intensive weeding, heavy manuring, and extensive use of mechanical tools and controlled irrigation.
Rice is not cultivated in northern parts of China because the climate is too cold and the growing season is too short for rice cultivation.

Teacher's Note:
a) Highlight transplanting and high-yielding intensive care in the Japanese method.
b) Temperature constraints explain the absence of rice in northern China.

Question 7.

(a) Give two reasons to explain why transport plays an important part in the development of India. [2 Marks]

Teacher's Note:
a) Focus on economic integration and emergency accessibility.
b) Keep answers focused on developmental impacts.

(b) (i) With reference to railway transport, differentiate between fare and freight. [4 Marks]
(ii) Why is there a distinct contrast in the railway network between the Eastern and the Western coastal plains?

Answer:
(i) Fare is the monetary charge levied by railways for carrying passengers, whereas freight is the charge levied for transporting goods, luggage, and cargo from one place to another.
(ii) The Eastern coastal plain is broad, level, and crossed by wide river deltas, allowing a continuous trunk rail line (like the Howrah - Chennai line) to be easily constructed. In contrast, the Western coastal plain is narrow because the Western Ghats lie very close to the sea, posing severe engineering obstacles. However, the construction of the Konkan Railway has now bridged this gap through numerous bridges and tunnels.

Teacher's Note:
a) Define fare and freight clearly as passenger versus cargo charges.
b) Explain physiographic differences (width of coastal plains and proximity of Western Ghats) to justify the contrast in rail density.

(c) (i) State two advantages of water transport. [4 Marks]
(ii) Mention any two factors that hinder inland water transport in India.

Answer:
(i) 1. Water transport is the cheapest mode of transport, highly suitable for carrying heavy and bulky goods over long distances.
2. It is fuel-efficient and environmentally friendly compared to road and rail transport.
(ii) 1. Competition from faster road and rail networks.
2. Seasonal fluctuations in water levels, silting of riverbeds, and lack of adequate navigational infrastructure.

Teacher's Note:
a) Highlight cost-effectiveness and eco-friendliness for water transport.
b) Mention seasonal navigability and competition as primary hurdles for inland waterways.

Question 8.

(a) What are industrial clusters? State any two indices used to identify industrial clusters. [3 Marks]

Answer:
Industrial clusters refer to concentrations of interconnected industries and firms in a specific geographic region due to favorable locational factors.
Two indices used to identify industrial clusters are:
1. Average daily factory employment or number of industrial workers.
2. Quantum of power used for industrial purposes.

Teacher's Note:
a) Define agglomeration and localization of industries as industrial clusters.
b) Employment size and power consumption are standard official indices.

(b) Examine the role played by the availability of raw materials in influencing location of industries. [2 Marks]

Answer:
Raw material availability is a primary factor in industrial location, especially for weight-losing industries (like iron and steel, sugar, and jute) where transporting bulky raw materials over long distances is uneconomical. Industries tend to locate near the source of raw materials to minimize transport costs and prevent spoilage.

Teacher's Note:
a) Emphasize weight-losing raw materials and transport cost minimization.
b) Give examples like sugar mills near sugarcane fields or iron and steel plants near coal and iron ore fields.

(c) Where is Visvesvaraya Iron and Steel Limited located? How has this steel plant overcome the disadvantage of not being located near any coal mining region of India? [3 Marks]

Answer:
Visvesvaraya Iron and Steel Limited (VISL) is located at Bhadravati in the Shimoga district of Karnataka.
It overcame the disadvantage of lacking local coal supplies initially by using charcoal obtained from nearby forests for smelting iron ore, and later by utilizing cheap hydroelectric power generated from the Sharavathi Power Project.

Teacher's Note:
a) Mention Bhadravati, Karnataka as the location.
b) Highlight the historical use of wood charcoal and subsequent shift to Sharavathi hydel power.

(d) With reference to tourism in India, explain : [2 Marks]
(i) Heritage Hotels

Answer:
(i) Heritage Hotels: Running hotels housed in old palaces, forts, castles, havelis, or hunting lodges built prior to 1950, preserving their traditional architecture, ambiance, and cultural heritage.
(ii) Eco - tourism: A form of tourism involving travel to fragile, pristine, and usually protected natural areas, aimed at low environmental impact, educating travelers, and supporting local community conservation.

Teacher's Note:
a) Heritage hotels convert historical palaces into tourist accommodations while retaining architectural integrity.
b) Eco-tourism emphasizes environmental conservation and community benefit.

Question 9.

(a) What does a geographer's concept of development comprise? [2 Marks]

Answer:
A geographer's concept of development is comprehensive, integrating economic progress with social advancement, political empowerment, cultural enrichment, and environmental preservation. It focuses on the sustainable use of natural and human resources to improve the overall quality of life.

Teacher's Note:
a) Emphasize the multi-dimensional nature of geographic development (economic, social, and environmental).
b) Avoid viewing development solely as economic growth.

(b) Explain what are macro regions, giving at least one example from India. [3 Marks]

Answer:
Macro-regions are large-scale planning units characterized by distinct physical, economic, and socio-cultural homogeneity and self-contained resource systems capable of supporting regional development. They represent the highest tier in regional planning.
Example: The Indo-Gangetic Plain or the South Peninsular Region.

Teacher's Note:
a) Define macro-regions as top-tier planning units based on socio-economic and physiographic integration.
b) Give clear Indian regional examples.

(c) How was the state of Chhattisgarh created? State any two features of agriculture practised in Chhattisgarh. [3 Marks]

Answer:
Chhattisgarh was carved out of the state of Madhya Pradesh on November 1, 2000, primarily to address the socio-economic underdevelopment and aspirations of its large tribal population.
Two features of agriculture in Chhattisgarh are:
1. Rice is the predominant crop, earning the region the title of the 'Rice Bowl' of India, cultivated extensively in the Mahanadi basin.
2. Kharif is the main cropping season, with about 35 percent of the total geographical area under cultivation.

Teacher's Note:
a) Mention the bifurcation from Madhya Pradesh and the tribal development objective.
b) Highlight rice dominance and kharif cropping seasonality.

(d) Explain with reference to its location, how Haldia Port has helped release congestion at Kolkata Port. [2 Marks]

Answer:
Haldia Port is located downstream on the Hooghly River, about 105 km from Kolkata. Being closer to the sea, it can receive large ocean-going vessels and deep-draft ships that cannot navigate the shallow upper reaches of the Hooghly to reach Kolkata, thereby successfully sharing the cargo load and easing congestion at Kolkata Port.

Teacher's Note:
a) Emphasize Haldia's downstream location on the Hooghly River.
b) Explain how handling larger vessels relieves pressure on the Kolkata dock system.
