Important Questions
✅ Very Short Answer (1 Mark)
Q1. What is a resource?
Ans: Everything available in environment that satisfies human needs, with tech access & economic feasibility.
Q2. Which soil is best for cotton? Ans: Black soil (Regur).
Q3. What is Agenda 21? Ans: Action plan for global sustainable development adopted at Rio Summit 1992.
Q4. Name one state affected by gully erosion. Ans: Madhya Pradesh (Chambal region).
✅ Short Answer (3 Marks)
Q1. Distinguish between renewable and non-renewable resources with examples.
Ans: Renewable → can be replenished (solar, wind); Non-renewable → limited stock (coal, petroleum).
Q2. Explain any three methods of soil conservation.
Ans: Contour ploughing, terrace farming, shelter belts.
Q3. Why is resource planning needed in India? Ans: (1) Unequal distribution, (2) Prevents over-exploitation, (3) Avoids regional conflicts.
✅ASSERTION & REASON
Q1. Assertion (A): Black soil is also called Regur soil.
Reason (R): It is rich in calcium carbonate and magnesium.
Ans: (B) Both A and R are true, but R is NOT the correct explanation of A. (Regur comes from “reg” meaning cotton; chemical composition is separate fact)
Q2. Assertion (A): Laterite soil is not fertile for agriculture.
Reason (R): High rainfall causes leaching of nutrients.
Ans: (A) Both A and R are true and R is the correct explanation.
✅ SOURCE-BASED (PASSAGE) QUESTION
“Resources are not, they become. It is human skills and technology that convert natural substances into usable resources.”
Q1. What does the statement mean?
Ans: Natural substances become resources only when humans develop technology and skills to use them.
Q2. Give an example where technology converted a substance into a resource.
Ans: Petroleum was not a resource until drilling technology and refining processes were developed.
✅ HOTS QUESTIONS (HIGHER ORDER THINKING)
Q1. “India has vast resources but still there are poor and deprived regions.” Why?
Ans: Unequal distribution, lack of technology, under-utilization, social barriers (caste/gender), and poor resource planning.
Q2. Can a resource become a liability? How?
Ans: Yes. Over-exploitation leads to degradation (e.g., groundwater overuse causing land subsidence). Also, toxic minerals (uranium waste) become hazardous.
✅ CASE STUDY QUESTION
The Chambal region across Madhya Pradesh and Uttar Pradesh has deep ravines formed by gully erosion. Farmers have lost agricultural land, and the area is now infamous for ravines and dacoits.
Q1. What type of erosion is seen in Chambal?
Ans: Gully erosion.
Q2. Suggest two conservation methods for this region.
Ans: (1) Afforestation on ravine banks. (2) Check dams to slow water flow.
✅ MCQs with Answers

📊 Previous Year Question Trends (2019-2024)
- Classification of resources – asked 12+ times across boards
- Soil types – name + features + states – 18 times
- Land degradation causes & conservation – 14 times
- Sustainable development & Agenda 21 – 10 times
- Map – soil distribution – 8 times
❌ Common Mistakes Students Make
- Confusing “Stock” and “Reserves” — Stock = no technology; Reserves = tech available.
- Writing “black soil in Punjab” — wrong: Black soil is Deccan region (Maharashtra, MP, Gujarat).
- Forgetting Agenda 21 year (1992).
- Not practising map work — easy 1 mark loss.
📘 Smart Revision Notes (Last-Minute)
- Resources classification (4 bases): Origin, Exhaustibility, Ownership, Development.
- Memory for 8 soil types: “All Black Red Later, Arid Forest Peat Saline”
- Land conservation methods: Afforestation, Contour ploughing, Terrace farming, Shelter belts, Strip cropping, Mulching.
- Rio Summit 1992: Agenda 21 → 179 countries → sustainable development goals.
C = Contour ploughing, A = Afforestation, T = Terrace farming, S = Shelter belts, M = Mulching.
📅 One-Day Revision Strategy

✍️ Exam Writing Tips
- Draw flowchart for “Classification of Resources” — teacher’s favourite.
- Use table for soil types — neat and saves time.
- Underline keywords: sustainable, Agenda 21, gully erosion.
- For 5-mark answers: Introduction → main points with examples → conclusion.
- Map work: use pencil, clear labelling, no shading outside boundary.
