1. Suggest two bases on which we can group objects.
Ans:
- Materials used in making objects (wood, metal, plastic).
- Properties of materials such as hardness or solubility.
2. Is oil soluble in water? Explain.

Ans:
Temperature is the measure of the hotness or coldness of a body.
Section F โ Long Answer Questions
1. Cutting down trees on a large scale impacts the quality of soil. Why?
Ans:
Trees hold the soil with their roots. When trees are cut, soil becomes loose and gets washed away by wind and rain. This causes soil erosion and decreases soil fertility.
2. Discuss similarities and differences in the life cycle of plants and animals.
Similarities:
- Both grow and develop.
- Both reproduce.
- Both have a life cycle.
Differences:
- Plants grow from seeds, animals from eggs or birth.
- Plants make their own food; animals cannot.
- Plants stay in one place, animals move.
3. Why do we say that petroleum is a non-renewable resource?
Ans:
Petroleum takes millions of years to form inside the Earth. It cannot be replaced quickly once used, so it is called a non-renewable resource.
