Question 10.
Which is the largest mineral based industry in India? Write the features of this industry using the hints given.
Hints:
Raw materials
Locational factors
Mining possibilities
Answer:

• Iron and steel industry is the largest mineral-based industry in India.
• Raw materials: Iron ore, coal, manganese, limestone and dolomite.
• Locational factors: Availability of raw materials, transportation facilities, availability of water, export facilities, availability of labour, cheap availability of power, etc.
• Mining possibilities: Iron is extracted from iron ore. Nearly 20% of the total iron ore reserves in the world is in India. The major mining centres of iron ore in India are :
  Sundargarh, Mayurbhanj – Odisha Singhbhum – Jharkhand Bellary, Chikmagalur – Karnataka
• Manganese: This is a metallic mineral largely used in the iron and steel industry. Odisha, Karnataka and Maharashtra are the leading producers.
• Coal: This is the major source of thermal power in India. West Bengal, Jharkhand and Odisha are the major producing states.

Question 11.
Hints about two agricultural crops of India are given. Identify the crops and write the geographical conditions for their cultivation.
A. Cultivated in hill slopes with well-drained soil rich in humus content.
B. The raw material for the largest agro-based industry in India.
Answer:

A.Tea:

• 25°C to 30°C of temperature.
• Annual rainfall range of200 to 250 cm.
• Well-drained soil rich in humus content.

B. Cotton:

• 20°C to 30°C of temperature.
• Small amount of annual rainfall.
• Black soil and alluvial soil.

Question 12.
Identify the regions where the following agricultural crops are cultivated. Also write the geographical conditions for their cultivation.
Rubber
Coffee
Answer:
Rubber: Rubber is mainly cultivated in Kerala. Certain parts of Tamil Nadu and the Andaman Nicobar Islands have small scale rubber cultivation. Rubber cultivation requires temperature above 25°C and rainfall of more than 150cm. Laterite soil is suitable.

Coffee: Coffee plantations of India are confined to the Western Ghat ranges of Karnataka, Kerala and Tamil Nadu. Two-third of the total production is from Karnataka. Moderate temperature and high rainfall are required for coffee cultivation.

Question 13.
Write the reason for the following.
Rice is cultivated widely in Kerala, but wheat is not cultivated.
Hint: Answer based on geographical requirements.
Answer:
Rice requires high temperature (above 24°C) and a good amount of rainfall (more than 150cm). These conditions favour rice cultivation in Kerala. But wheat is cultivated mainly in temperate regions. It requires 10°C to 26°C temperature and 75cm of rainfall for its cultivation. These conditions are not present in Kerala, which is a tropical region.

Alluvial soil is suitable for rice cultivation. Well drained alluvial soil is ideal for wheat cultivation. Kerala which receives more than 200cm rainfall does not have well drained alluvial soil.
Since the above mentioned geographical factors are not present in Kerala, wheat is not cultivated here.

Question 14.

Question 2.
Prepare a note Of any three cash crops cultivated in India, the geographical conditions for their cultivation and the states
leading in ‘heir cultivation.
Answer:
Cash crops are those having industrial and commercial significance. These are the raw- materials for agro based industries. Cotton, jute and sugarcane are the major cash crops.

Sugarcane: Sugarcane, a tropical crop, requires hot and humid climate, requires hot and humid climate.
Alluvial soil and black soil are suitable. The leading sugarcane producing state is Uttar Pradesh followed by Maharashtra, Karnataka and Tamil Nadu. Sugar and jaggery are produced from sugarcane.

Cotton: Cotton is a fibre crop. Cotton requires frost-free growing season, 20°C to 30°C temperature and small amount of rainfall.
Black soil and alluvial soil are suitable. Maharashtra and Gujarat are the leading producers. Cotton is the raw material for cotton textile industry.

Jute: Jute is also a fibre crop. Hot and humid conditions are ideal for its cultivation. High temperature and rainfall above 150 cm are essential. Well drained alluvial soil is required. The Ganga-Brahmaputra delta region of West . Bengal is the major jute producing region.

Question 3.
By analysing the various means of transportation, prepare a seminar on the topic ‘ ‘Influence of transportation on the life of the people of India. ’
Answer:
Seminar
Topic: ‘Influence of transportation on the life of the people of India.’
Transport routes are considered as the lifeline of a nation. They connect different comers of the country and bring people together. Efficient mode of transport is essential for ensuring the infrastructure in the areas of production and to bring the products to the consumers.The role played by transportation routes in the process of urbanization, in addition to industrialisation is decisive.

Transportation helped in linking rural and urban areas and expediting the process of urbanization. Modes of transport are selected in accordance with the physical characteristics of each region. The various means of transportation in India are discussed below.

Road transport: Road transport is the most important means to link the rural and urban centres scattered throughout the country. India is one of the countries of the world with a broad network of roads. The influence of topography is decisive in the building and development of roads. Road networks are mainly found in the Northern Plains, the coastal plains and in the Deccan Plateau. But road network is comparatively less in the Himalay an region and in the North-Eastern states. In India roads are classified based on the construction and management.

• National Highways: The major roads in the country that link state capitals, major cities and ports. Construction and management of these roads are done by the Union Ministry.
• State Highways: They are the major roads in a state and link state capitals with district headquarters. The construction and maintenance are done by the State Governments.
• District Roads: These link district headquarters with important places within a district. The construction and maintenance are done by District Panchayats.
• Rural Roads: Village roads ensure domestic movement. These are constructed and maintained by local self government.

Golden Quadrangle Super Highway is the six lane superhighways, connecting the metropolitan, cities of Delhi, Kolkata, Mumbai and Chennai. The National Highway Authority oflndia is responsible for such roads.

Railways: India has the largest network of railways in Asia. It is the suitable means of transport for both the passenger and heavy’ cargo transport. Railway network is seen more in Great Plains, Gujarat and Tamil Nadu. For administrative convenience, the Indian Railway is divided into 16 zones. Metro rail projects are being established in cities

Water transport: The cost of construction and maintenance of water transport routes is less compared to that of road and railway networks. Moreover, this does not cause environmental pollution. It is suitable for large scale cargo transport. Rivers, canals and long coastline increase the possibility of water transport in India. Water transport is divided into marine transport and inland water-transport. Transportation through the rivers and lakes inside the land is known as inland water transport.

India’s inland water transport is concentrated in the river Ganga, Brahmaputra and in their tributaries, river Godavari-Krishna and in tributaries, in Buckingham canals of Andhra Pradesh and Tamil Nadu, river Mandovi and river Suvari in Goa and in the backwaters of Kerala. India has a long coastline. The west and east coasts of India have immense potential for marine transport. The 12 major ports and 185 minor ports on the east and west coasts of India play a decisive role in international trade and in the country’s economy.

Airways: Airways are the most speedy and the most expensive mode of transportation. In rug¬ged terrain and in places which cannot be reached by roads and railways, airways are the only means of transportation. The air traffic in India is under the control of the Airport Authority of India. There are 126 airports including 11 international airports under this establishment. The international services are handled by Air India and domestic flights by Indian Airlines. A number of private companies also operate flight service. Means of transport thus play a decisive role in the economic progress, cultural unity and national integration.
