Question 7. What are the sources of water? Explain them with special reference to their pollution and the remedial measures of water pollution.
Answer:
Effects of Water Pollution: Water pollution happens when pollutants change the water's physical and chemical makeup. This makes the water unsafe to drink and harmful to living organisms. Water sources like rivers, tanks, and springs often get polluted.
The major sources of water are:
2. Hand Pump Water: Water from hand pumps is generally good for drinking, as long as it isn't too hard or acidic.
3. Tank-Water: Water collected in tanks from rain or hills is used by people, animals, and for irrigation. This tank water is not always pure. It should be boiled or filtered before drinking. Storing water in tanks requires regular cleaning to prevent contamination.
4. River Water: Rivers flow quickly, and their water is usually pure at its source due to contact with air. However, it gets polluted downstream from poisonous plants in hilly areas and from city drains mixing with it.
5. Well Water: Water from deep wells is typically pure. Its purity should be maintained by adding alum, lime, or Potassium Permanganate every month.
General remedial suggestions for water pollution:
1. Septic tanks should be used in every house.
2. Industrial waste should not be dumped into rivers.
3. The use of pesticides like D.D.T. should be limited.
4. Plastic bags and food waste should not be thrown into open drains.
5. Rivers should not be used for bathing or washing clothes.
6. Waste products should be recycled whenever possible. Taking these steps can significantly improve water quality and protect our water resources.
In simple words: Water pollution makes water bad for drinking and harms life. Sources like hand pumps, tanks, rivers, and wells can be polluted. To fix this, we should use septic tanks, stop industries from dumping waste, use fewer pesticides, avoid throwing trash in drains, keep rivers clean from bathing, and recycle waste.

🎯 Exam Tip: Structure your answer by first explaining pollution effects, then describing various water sources and their pollution risks, and finally outlining specific remedial measures.

Question 8. Explain the main causes of air pollution.
Answer: Air pollution is caused by many factors:
1. Transportation: The number of vehicles in cities is growing daily. The smoke from these vehicles, which use diesel and petrol, releases harmful gases into the air. This pollutes the atmosphere and uses up oxygen. Checking these pollutants is important.
2. Industrialization: Fast growth of industries creates many poisonous gases, like carbon dioxide. This increases carbon dioxide and decreases oxygen, causing an imbalance in the air.
4. Use of Pesticides: Many pesticides are used today to protect crops from insects, fungi, and rodents. Too much use of these chemicals, however, pollutes the atmosphere.
5. Unhealthy sanitary conditions: Piles of trash in residential areas pollute the surrounding air. So, household waste should be disposed of without causing more pollution.
6. Dead animals, dry leaves, and household waste also pollute the air.
7. Burning cooking fuels and microbes also release pollutants.
8. Smoke from cars and other vehicles adds to air pollution.
9. If homes and factories do not have good ventilation, carbon dioxide levels increase and oxygen levels decrease.
10. Other air pollutants include nitrogen oxides, fluorides, ozone, smoke, and fog. Reducing these sources is key to cleaner air. Each of these sources adds a layer of complexity to the problem of air quality.
In simple words: Air pollution comes from many things like vehicle smoke, factory gases, pesticides, and piles of garbage. Burning fuel, lack of fresh air indoors, and other chemicals like nitrogen oxides also make the air dirty.

2. It should be centrally located.
3. It should be away from railway stations and factories.
4. It should be away from slums and trash storage areas.
5. It should be open to sunlight.
6. It should have a large playground. A well-chosen location contributes significantly to student well-being.
Direction of the school building: When building, make sure there is enough natural sunlight and fresh air.
Seating Arrangement in the school: The type of furniture for children and how it is placed in classrooms also greatly affects their comfort and learning. Good design promotes focus.
In simple words: When building a school, choose a location that is open, airy, central, and far from noisy factories or dirty areas. Make sure the building gets lots of sunlight and fresh air. Also, have a big playground and comfortable seating inside.

🎯 Exam Tip: Divide the answer into key areas like location, building orientation, and facilities. For location, list multiple criteria such as safety, access to light and air, and distance from pollution sources.
