1. 1. What will happen if we do not get timely rains? (Page 178)
   Answer: Crops will dry up, leading to food scarcity, drinking water shortages, droughts, and loss of livelihood for farmers.
2. 2. What will happen if it rains during harvesting time? (Page 178)
   Answer: Harvested crops will get damaged, decay in the fields, and cause severe financial loss to farmers.
3. 3. Have you ever heard about flash floods? (Page 180)
   Answer: Yes, flash floods are sudden, intense floods caused by extremely heavy rainfall over a short period.
4. 4. Have you experienced floods in your area? (Page 180)
   Answer: Yes, during heavy rainy seasons, low-lying areas get submerged in water, blocking roads and disrupting normal life.
5. 5. What are the reasons for climate change? (Page 180)
   Answer: Climate change is caused by natural factors (volcanoes, cyclones) and human activities (cutting trees, burning fossil fuels, air/water pollution).
6. 6. Have you ever experienced a cyclone? (Page 182)
   Answer: Yes, cyclones bring high-speed winds and continuous heavy rainfall that can damage trees and power lines.
7. 7. Is climate change the reason for cyclones? (Page 182)
   Answer: Cyclones are natural phenomena, but when they become unusually frequent and severe, it is due to climate change.
8. 8. Is the use of plastic pens eco-friendly? (Page 184)
   Answer: No, disposable plastic pens do not decompose easily in soil, creating non-degradable waste that harms the environment.
9. 9. Why are disposable plastic pens harmful to the environment? (Page 184)
   Answer: Disposable plastic pens end up in landfills or water bodies, blocking soil absorption and polluting water resources because plastic does not decompose.
10. 10. What are the advantages of using paper pens or other eco-friendly alternatives instead of plastic pens? (Page 184)
    Answer: Paper pens and reusable metal pens are biodegradable or recyclable, reducing plastic waste and protecting soil and water health.
11. 11. Do you like this school? What can we do? (Page 184)
    Answer: No, the school area is polluted with plastic waste. We can organize a clean-up drive, place dustbins for waste segregation, stop using plastic, and plant flowering saplings.
12. 12. What can happen to the soil if it gets fully covered with plastic? (Page 186)
    Answer: Plastic forms an impenetrable barrier that prevents rainwater from sinking into the ground, reducing groundwater recharge and killing beneficial soil organisms.
13. 13. Read the news item on Uttarakhand forest fires. What does the news item refer to? (Page 186)
    Answer: It refers to raging forest fires across Uttarakhand hills that destroyed thousands of hectares of forest due to severe heatwaves and dry weather.
