Class 5 EVS - Complete In-Text & Exercise Questions

PART 1: IN-LESSON QUESTIONS

A

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.
14. 14. What is the cause for this incident? (Page 186)
    Answer: The main causes are early heatwaves, dry winter conditions, global warming, and excess heat in the atmosphere.
15. 15. Which plate is not eco-friendly? Why? (Page 192)
    Answer: Plastic plates are not eco-friendly because they do not decompose, whereas banana leaves and steel plates are natural and reusable.
16. 16. Are we celebrating our festivals in an eco-friendly way? (Page 194)
    Answer: Often no, because immersing Plaster of Paris (POP) idols, bursting firecrackers, using chemical Rangoli colors, and serving food in single-use plastic causes air and water pollution.

PART 2: IMPROVE YOUR LEARNING

B

1. 1. What is climate?
   Answer: The weather conditions such as temperature, rainfall, etc., prevailing in an area over a long period of time are called climate.
2. 2. Write any two causes of climate change.
   Answer:
   i) Indiscriminate cutting of trees (Deforestation).
   ii) Excessive burning of fossil fuels and air pollution from vehicles and factories.
3. 3. What is global warming?
   Answer: Global warming is the gradual rise in the Earth's average temperature over time due to pollution, deforestation, and greenhouse emissions.
4. 4. Which human activity is a major cause of climate change? (  B  )
   A) Gardening at home

   B) Factory smoke and deforestation

   C) Drinking clean water

   D) Children playing outdoor games
   Correct Answer: B) Factory smoke and deforestation
5. 5. How does deforestation affect climate?
   Answer: Deforestation decreases tree cover, leading to reduced rainfall, increased atmospheric heat/carbon dioxide, soil erosion, and global warming.
6. 6. Why should we protect forests and trees?
   Answer: Forests act as the lungs of the Earth. They produce oxygen, bring rainfall, prevent soil erosion, maintain ecological balance, and shelter wildlife.
7. 7. Villagers cut many trees to build houses. What change may happen to the climate of that area?
   Answer: The area will experience higher temperatures, lower rainfall, drying water bodies, and frequent soil erosion due to loss of tree cover.
8. 8. List two eco-friendly practices you can follow at home.
   Answer:
   i) Carry cloth or paper bags instead of plastic bags.
   ii) Switch off lights and fans when leaving a room to conserve electricity.
9. 9. Classify the following causes of climate change into natural and human-made:
       a) Volcanic eruption    b) Cutting trees    c) Burning fossil fuels    d) Floods
   Answer:
   Natural Causes: Volcanic eruption, Floods
   Human-Made Causes: Cutting trees, Burning fossil fuels
10. 10. Observe the process used for disposing of garbage at your home and make a report.
    Answer: At our home, we segregate waste into wet waste (kitchen waste) and dry waste (paper, plastic). Wet waste is used as manure for plants, while dry waste is collected by municipal workers.
11. 11. People say climate change is everyone's problem. Explain.
    Answer: Climate change affects everyone through erratic rains, droughts, heatwaves, and storms. Since human activities worldwide contribute to pollution, protecting the environment requires collective effort.
12. 12. Why should we appreciate movements that protect the environment?
    Answer: Movements like the Chipko Movement raise public awareness, prevent mass deforestation, and protect natural habitats for future generations.
13. 13. Prepare some slogans on 'Save the Environment'.
    Answer:
    i) "Save Trees, Save Future!"
    ii) "Plant a Tree Today, Enjoy Clean Air Tomorrow!"
    iii) "Say NO to Plastic, Say YES to Earth!"
14. 14. Suggest a few proposals to reduce vehicle pollution in your area.
    Answer:
    i) Walk or cycle for short distances.
    ii) Use public transport or carpooling.
    iii) Get vehicles serviced regularly for emission control.
