Ques.2: Answer the following briefly in not more than 30 words.
(i) What is manufacturing?
(ii) Name any three physical factors for the location of the industry.
(iii) Name any three human factors for the location of an industry.
(iv) What are the basic industries? Give an example.
(v) Name the important raw materials used in the manufacturing of cement?
(i) The processing of raw materials in industries to produce valuable goods in large quantities is known as manufacturing. For example, making furniture from wood.
(ii) The physical factors for the location of the industry are the availability of raw materials, availability of energy source and proximity to the market.
(iii) The human factors for the location of an industry are the availability of labour, availability of cheap labour and accessibility to the cities.
(iv) The industries whose produced goods are used as raw materials for other industries are known as basic industries. These industries provide the raw material for other industries. For example, iron and steel industry.
(v) The important raw materials used in the manufacturing of cement are limestone, silica and gypsum.
Ques.3: Write the answers to the following questions in 120 words.
(i) How are integrated steel plants different from mini steel plants? What problems does the industry face? What recent developments have led to a rise in the production capacity?
(ii) How do industries pollute the environment?
(iii) Discuss the steps to be taken to minimise environmental degradation by industry.
(i) The integrated steel plants, as the name suggests, are large plants where all the simple and complex are carried out from the assembling of the raw material to its rolling, shaping, and steel making. Whereas mini steel plants are smaller. They use steel scrap and sponge iron. They use electric furnaces and re-rollers. Mild and alloy steel is produced by these plants. The problems faced by the industry are poor infrastructure, lower productivity of labour, high costs and limited availability of coking coal, and irregular supply of energy. The recent developments that have led to a rise in the production capacity of the iron and steel industry are liberalisation and foreign direct investment.
(ii) The industries pollute the environment in the following ways:
- The industries pollute the air by discharging the smoke into the atmosphere without filtering. Brick kilns and chemical factories emit smoke which consists of dust and other harmful particles and gases which are atmospheric pollutants. Burning of fossil fuels also adds toxins into the atmosphere. Major atmospheric pollutants are Sulphur dioxide and carbon monoxide.
- Water pollution is caused by the discharge of untreated industrial effluents into water bodies. This not only pollutes the water but is also harmful to aquatic life as it damages the aquatic ecosystems. Such industries include paper industries, petroleum refineries, fertilizer and pesticide industry, etc.
- Thermal pollution is another type of pollution whereby the hot water from the industries is discharged into lakes and other water bodies without cooling. This disturbs the natural temperature of the water bodies and results in the death of many plants and animals in the aquatic life, thereby damaging the aquatic ecosystem.
- Noise pollution caused by large industries mainly results in psychological and physiological impacts, it may cause feelings of irritation and anger and can cause impaired hearing, risk of high blood pressure, etc.
(iii) The steps to be taken to minimise the environmental degradation by industry can be:
- The water used in the industries could be recycled. This would minimise the use of water.
- Rainwater harvesting should be encouraged.
- The water should be treated before being discharged into the water bodies.
- Energy-efficient technology must be out to use.
- Filtering of smoke should be done before discharging into the atmosphere.
- Silencers could be used to minimise noise pollution.
