Why did Mahatma Gandhi lay emphasis on spinning yarn and weaving khadi Answer: Mahatma Gandhi in order to promote swadeshi goods encouraged the people to spin yarn and weave khadi.
During the colonial period, the British had uprooted the Indian textile industries by replacing them with the British mill-made goods especially the textiles. This adversely affected the weavers. They lost their livelihood due to the closure of several Indian handloom industries.
So, Gandhiji encouraged Indians to spin yam and weave khadi. This served twin purposes � it spread nationalism and provided work to poor artisans and weavers. Question 2. Why is it important for our country to keep the mill sector loomage lower than powerloom and handloom? Answer: It is because powerlooms and handlooms are the tools of the poor artisans and weavers in India with which they earn their livelihood.
If the mill sector loomage is encouraged, it will affect them adversely. They will lose their livelihood. So keeping the welfare of these poor artisans and weavers in mind, it is important to keep mill sector loomage lower than powerloom and handloom. Question 3.
Why is it important for us to improve our weaving sector instead of exporting yarn in large quantities? Answer: Weaving is highly decentralised to provide scope for incorporating traditional skills and designs of weaving in cotton, silk, zari, embroidery,etc. India has world class production in spinning, but weaving supplies low quality of fabric as it cannot use much of the high quality yarn produced in the country. Weaving is done by handloom, powerloom and in mills.
The handspun khadi provides large scale employment to weavers in their homes as a cottage industry. Multiple Choice Questions i Which one of the following industries uses limestone as a raw material? Answer: Manufacturing is production of goods in large quantities after processing from raw materials to more valuable products.
For example, sugar is manufactured from sugarcane, iron and steel from iron ore, etc. Answer: a Availability of raw material b Availability of water and power supply c Availability of transport facilities. Give an example. Answer: Industries that supply their products or raw materials to manufacture other goods are called basic or key industries.
For example, iron and steel, copper smelting and aluminum smelting etc. Answer: a Limestone b Silica c Alumina, and d Gypsum. Write the answers of the following questions in words. What problems does the industry face? What recent developments have led to a rise in the production capacity? Answer: Integrated steel plants are large which handle everything in one complex from putting together raw material to steel making, rolling and shaping.
So far mini steel plants are concerned, they are smaller, have electric furnaces, use steel scrap and sponge iron. They have re-rollers that use steel ingots as well. They produce mild and alloy steel of given specifications.
The industry faces several problems. Some of them are:. Liberalisation and foreign direct investment FDI have given a boost to the industry with the efforts of private entrepreneurs. There is a need to allocate resources for research and development to produce steel more efficiently.
The increase in pollution of land, water, air and noise due to industries cannot be ignored. Industries are responsible for four types of pollution-air, water, land and noise.
The polluting industries also include thermal power plants. Air borne particulate materials contain both solid and liquid particles like dust, sprays mist and smoke. Smoke is emitted by chemical and paper factories, brick kilns, refineries and smelting plants and burning of fossil fuels in factories. Dumping of wastes specially glass, harmful chemicals, industrial effluents, packaging, salts and garbage renders the soil useless. Answer: The following steps can be taken to minimise environmental degradation by industry: a Minimising use of water for processing by reusing and recycling it in two or more successive stages.
Treatment of industrial effluents can be done in three phases:. Machinery can be redesigned to increase energy efficiency and reduce noise. Activity Give one word for each of the following with regard to industry. The number of letters in each word are hinted in brackets. Project Work Select one agro-based and one mineral based industry in your area. Answer: Do it yourself. Activity Solve the puzzle by following your search horizontally and vertically to find the hidden answers.
Textiles, sugar, vegetable oil and plantation industries deriving raw materials from agriculture are called� 2. The basic raw material for sugar industry. Iron-ore, coking coal, and limestone are the chief raw materials of this industry.
A public sector steel plant located in Chhattisgarh. Railway diesel engines are manufactured in Uttar Pradesh at this place. Agro-based 2. Sugarcane 3. Jute 4. Iron and steel 5. Bhilai 6. Classify the following into two groups on the basis of bulk and weight of raw material and finished goods.
Make a list of all such goods made of steel that you can think of. Where would it be economically viable to set up the cement manufacturing units? Answer: The cement industry requires bulky and heavy raw materials like limestone, silica, alumina and gypsum. Therefore, this industry should be set up close to the areas where such minerals are found. This would reduce the cost of transportation of these materials. Apart from rail transportation regular availability of electric power is also taken into consideration while setting up the cement manufacturing units.
Question 4. Find out where the cement manufacturing plants are located in other states of India. Find their names.
