Answers for 2-Mark Questions | www.WithTeachers.in

Answer 🎯.1 On 3 December 1984, a tragic industrial accident occurred at Bhopal where deadly gas escaped from a chemical plant operated by Union Carbide into the atmosphere. Answer 🎯.2 The deadly gas killed over 4000 local residents and left a large section of the surviving population blind and crippled. Answer 🎯.3 An average adult exchanges 15 kg of air a day, compared to about 1.5 kg of food consumed and 2.5 kg of water intake. Answer 🎯.4 Pure dry air comprises 78 percent nitrogen, 21 percent oxygen, a little less than 1 percent argon, and 0.03 percent carbon dioxide. Answer 🎯.5 Air is said to be polluted when its composition is altered, such as when the oxygen level is reduced or irritating gases enter the atmosphere. Answer 🎯.6 Industries require steam and to produce it, they burn various fuels such as coal, coke, and furnace oil. Answer 🎯.7 Instead of disappearing, the smoke mingles with the atmospheric air, polluting it with obnoxious gases, ash, and dust particles. Answer 🎯.8 Thermal power stations are rated first among the industries that discharge high amounts of smoke and ash. Answer 🎯.9 Cement, steel, and ore processing industries are significant contributors to air pollution, along with chemical industries that release toxic fumes. Answer 🎯.10 It is reported that automobiles in Greater Kolkata alone spew about 1500 tonnes of pollutants into the atmosphere every day. Answer 🎯.11 A person living in Kolkata, whether a smoker or not, is forced to inhale toxic substances equivalent to smoking two packets of cigarettes a day. Answer 🎯.12 The number of vehicles is increasing dramatically to meet the demands of an exploding population. Answer 🎯.13 Automobiles are responsible for 60 percent of air pollution because they release maximum carbon monoxide into the atmosphere. Answer 🎯.14 If the menace of automobile exhausts continues, we may have to wear nasal filters on our nose in the future. Answer 🎯.15 Many flower and vegetable crops suffer ill effects from the toxic exhaust gases released by cars. Answer 🎯.16 Air pollution causes the rubber tyres on automobiles to crack and become porous. Answer 🎯.17 Fine buildings become shabby as their walls are blackened with soot that settles on them, and their surfaces may deteriorate. Answer 🎯.18 Air pollution causes eye irritations, scratchy throats, respiratory illnesses, and contributes to a number of serious diseases. Answer 🎯.19 Gases such as carbon dioxide, methane, and nitrous oxide are increasing and trapping radiation, eventually leading to global warming. Answer 🎯.20 Chlorofluorocarbons are a group of chemicals that may destroy the atmospheric layer that protects us from harmful kinds of solar energy. Answer 🎯.21 Acid rain or precipitation contains oxides of sulphur and nitrogen, along with other chemicals. Answer 🎯.22 In Sweden, 4000 lakes have been so severely affected by acid rain that no fish has survived. Answer 🎯.23 The Pied Flycatcher and the Apollo Butterfly are among the growing list of species threatened by acid rain in Sweden. Answer 🎯.24 Acid rain changes the soil's nutrient content by washing or leaching away essential nutrients like potassium, calcium, and magnesium from the upper layer. Answer 🎯.25 The three basic approaches are preventive measures (changing raw materials), dispersal measures (raising smokestacks), and collection measures (trapping pollutants).

Section B: 3-Mark Questions (20 Questions)

(Questions with immediate answers for www.WithTeachers.in)

Question ❓.1 Why does the text argue that air pollution is the greatest threat to mankind?

Answer 🎯.1 A person can survive without food or water for days, but cannot live without breathing for even a minute. Because an adult takes in 15 kg of air daily, the quantum of pollutants entering the body through respiration is manifold compared to contaminated food or water.

Question ❓.2 Describe how the burning of fuels in industries contributes to air pollution.

Answer 🎯.2 Industries burn fuels like coal, coke, and furnace oil to produce steam. This burning produces heat and smoke containing obnoxious gases, ash, and dust, which mingles with the atmosphere and turns our lungs into garbage dumps for pollutants.

Question ❓.3 Explain the alarming situation of automobile pollution in Indian cities.

Answer 🎯.3 Automobiles in Greater Kolkata spew 1500 tonnes of pollutants daily, forcing residents to inhale toxins equivalent to two packets of cigarettes a day. The pollution levels in Delhi, Mumbai, and Chennai are equally alarming due to the dramatic increase in vehicles to meet population demands.

Question ❓.4 What are the severe economic and material damages caused by air pollution?

Answer 🎯.4 Air pollution causes billions of dollars in losses each year. It damages crops, kills trees, poisons cattle, cracks automobile rubber tyres, and deteriorates fine buildings by blackening their walls with soot.

Question ❓.5 How does air pollution contribute to the phenomenon of global warming?

Answer 🎯.5 Expanding technological societies release increasing amounts of gases like carbon dioxide, methane, and nitrous oxide. These gases trap the solar radiation that reaches the earth, causing the atmosphere to become warmer and leading to global warming.

Question ❓.6 What is the danger posed by chlorofluorocarbons (CFCs)?

Answer 🎯.6 Chlorofluorocarbons are chemicals widely used as refrigerants and cleaners. Scientists are highly concerned because these widespread substances may destroy the critical atmospheric layer that protects the earth from harmful solar energy.

Question ❓.7 How does acid rain physically destroy forests?

Answer 🎯.7 Acid rain washes or leaches away vital nutrients like potassium, calcium, and magnesium from the upper layer of the soil. Stripped of these nutrients that help them grow, trees die, leaving behind large stretches of forests as leafless skeletons.

Question ❓.8 Detail the destructive impact of acid rain on aquatic life and animals.

Answer 🎯.8 Acid rain turns river and lake water acidic, poisoning aquatic plants and animals. For instance, fish cannot survive in 4000 affected lakes in Sweden, and the Dipper fish and Brown Trout have vanished from specific rivers and lakes in Wales and Norway.

Question ❓.9 What are the health hazards of acid rain on human beings?

Answer 🎯.9 Acid rain is highly detrimental to human health. It irritates the sensitive tissues of our eyes and lungs, which is particularly harmful to children, and it can also cause skin lesions.

Question ❓.10 How does air pollution severely affect historical buildings and monuments?

Answer 🎯.10 Beautiful old buildings and monuments are not spared from pollution. In Poland, the buildings of Krakow are slowly destroyed by acidic smog, and in highly polluted Athens, acid rain is eating into the marble of its world-famous monuments.

Question ❓.11 Why is controlling air pollution complicated by international boundaries?

Answer 🎯.11 Air pollution cannot be confined to one area because pollutants are carried by the wind across thousands of miles from one country to another. For example, acid rain originating in the United States caused the death of lakes in eastern Canada.

Question ❓.12 Describe the 'preventive' and 'dispersal' measures to control air pollution.

Answer 🎯.12 Preventive measures involve changing the raw materials used in industry or altering the ingredients of fuel to produce less smoke. Dispersal measures involve raising the heights of smokestacks to scatter the pollutants higher into the atmosphere.

Question ❓.13 How do 'collection measures' help in reducing industrial air pollution?

Answer 🎯.13 Collection measures focus on stopping pollutants before they leave the factory. This involves designing and installing special equipment in emission systems to trap the pollutants before they escape into the atmosphere.

Question ❓.14 How have automobile engines been modified to reduce air pollution?

Answer 🎯.14 To meet new environmental standards, automobile engines have been re-designed. New cars are equipped with advanced devices, such as the catalytic converter, which actively changes toxic pollutants into harmless substances before they leave the exhaust.

Question ❓.15 What is the financial cost of controlling air pollution, and is it worth it?

Answer 🎯.15 Vast sums of money will have to be spent on research and installing control devices in factories and new cars, which often leads to higher prices for consumers. However, to most people, this cost is fully justified to ensure we can breathe pure air.

Question ❓.16 Why do we refer to our lungs as "garbage dumps" in polluted cities?

Answer 🎯.16 Without our knowledge, we constantly respire polluted air containing obnoxious gases, ash, and dust particles spewed by industries and vehicles. Since we exchange 15 kg of this air daily, our lungs accumulate these toxins, acting like garbage dumps.

Question ❓.17 Discuss the impact of thermal power stations and chemical industries on air quality.

Answer 🎯.17 Thermal power stations are the worst offenders, discharging the highest amounts of smoke and ash into the air. Chemical industries further degrade air quality by releasing dangerous, toxic fumes along with heavy smoke into the atmosphere.

Question ❓.18 What vision for the future does the author offer at the end of the text?

Answer 🎯.18 The author expresses hope that despite the high costs and necessary research involving many scientists, the day will come when people everywhere can breathe pure air in cities where sunlight is no longer blocked by an umbrella of pollution.

Question ❓.19 Why are scientists alarmed about the changing composition of the atmosphere?

Answer 🎯.19 Pure air has a delicate balance, but scientists are alarmed because human activities are rapidly increasing the amounts of carbon dioxide, methane, nitrous oxide, and CFCs. This threatens to cause global warming and destroy the protective atmospheric layer.

Question ❓.20 How did the disaster in Bhopal serve as a warning about the severity of air pollution?

Answer 🎯.20 The Bhopal gas tragedy was a localized, extreme event where deadly gas killed over 4000 people and crippled many more. It serves as a stark warning because now every city and town is slowly facing a similar, chronic problem of poisoning from an expanding technological society.
