📖 PART A: Frequently Asked Questions (20 FAQs)
Questions students most commonly ask about Resources and Development.
-
Q: What is the main difference between a 'Resource' and a 'Stock'?
A: A Resource is a naturally occurring substance that is accessible and culturally acceptable for use. A Stock is material in the environment that has the potential to satisfy human needs but is not yet accessible due to lack of appropriate technology. Example: Hydrogen and Oxygen in water are a stock for energy, but water is a resource for drinking.
-
Q: Explain the classification of resources based on exhaustibility.
A: Two categories: Renewable Resources (can be renewed/replenished quickly, e.g., solar energy, wind, forests) and Non-Renewable Resources (have a limited stock, take millions of years to form, e.g., minerals, fossil fuels like coal & petroleum).
-
Q: What is Sustainable Development? Why is it important?
A: Development that meets the needs of the present generation without compromising the ability of future generations to meet their own needs. It is important to prevent over-exploitation of resources, ensure long-term resource availability, and maintain ecological balance.
-
Q: What are the main causes of resource depletion in India?
A: Major causes include: (1) Overpopulation leading to overuse (2) Unequal access to resources (3) Indiscriminate exploitation for economic growth (4) Industrialisation and urbanisation (5) Deforestation and soil erosion.
-
Q: What is meant by 'Resource Planning'? What are its stages?
A: Resource Planning is a strategy for the judicious use of resources. Its three stages are: (1) Identification and inventory of resources (2) Evolving a planning structure with appropriate technology and institutions (3) Matching the resource development plans with overall national development plans.
-
Q: Why is conservation of resources necessary?
A: Conservation is necessary because: (1) Resources are finite and non-renewable ones are depleting fast (2) Prevents environmental degradation and ecological imbalance (3) Ensures resources for future generations (4) Reduces wastage and promotes sustainable development.
-
Q: Distinguish between Khadar and Bhangar soils.
A: Khadar: New alluvial soil, found in flood plains, renewed every year, more fertile, fine texture. Bhangar: Old alluvial soil, found away from rivers (older plains), contains 'kankar' nodules, less fertile, coarse texture.
-
Q: What is soil erosion? Name the main types of soil erosion prevalent in India.
A: Soil erosion is the removal of the top fertile layer of soil by wind, water, or human activities. Main types in India are: (1) Gully erosion (Chambal ravines) (2) Sheet erosion (removal of thin layer by water) (3) Wind erosion (in arid areas like Rajasthan).
-
Q: What steps can be taken to control soil erosion?
A: Steps include: (1) Contour ploughing on slopes (2) Terrace farming (3) Strip cropping (4) Planting shelter belts of trees (5) Constructing dams and embankments (6) Restricting overgrazing and deforestation.
-
Q: How are human activities responsible for land degradation? Give examples.
A: Human activities like (1) Deforestation (2) Overgrazing (3) Mining and quarrying (leaving scars) (4) Over-irrigation (causing waterlogging and salinity) (5) Industrial effluents and waste dumping (6) Improper use of fertilizers degrade land.
-
Q: Why is land considered a natural resource of utmost importance?
A: Land supports natural vegetation, wildlife, human life, and economic activities (agriculture, forestry, mining, housing, industry). It is a fixed asset and the basis of all terrestrial ecosystems. Its quality determines the productivity and sustainability of life.
-
Q: What is the Rio de Janeiro Earth Summit, 1992? What was its significance?
A: It was the first international Earth Summit where over 100 world leaders met to address urgent environmental issues. Its significance: It endorsed the global Forest Principles and adopted Agenda 21 for achieving Sustainable Development in the 21st century.
-
Q: Explain Agenda 21.
A: Agenda 21 is a non-binding, voluntarily implemented action plan of the United Nations for Sustainable Development. It is a comprehensive blueprint to combat environmental damage, poverty, and disease through global cooperation for development that does not harm the environment.
-
Q: Classify resources on the basis of origin. Give examples.
A: (1) Biotic Resources: Obtained from the biosphere and have life, e.g., forests, animals, fisheries. (2) Abiotic Resources: Composed of non-living things, e.g., rocks, metals, wind, solar energy.
-
Q: What are the major soil types found in India? Name one region for each.
A: (1) Alluvial Soil: Indo-Gangetic plains (2) Black Soil (Regur): Deccan Plateau (3) Red and Yellow Soil: Parts of Odisha, Chhattisgarh (4) Laterite Soil: Western Ghats region (5) Arid Soil: Rajasthan (6) Forest Soil: Hilly areas of Jammu & Kashmir, Himachal.
-
Q: Why is black soil ideal for growing cotton?
A: Black soil (Regur) is clayey, deep, and retains moisture well. It is rich in soil nutrients like calcium carbonate, magnesium, potash, and lime. These properties, along with its ability to develop deep cracks in hot weather (helps in aeration), make it ideal for cotton cultivation.
-
Q: What is wasteland? How can it be reclaimed?
A: Wasteland is degraded land that is currently unproductive. It can be reclaimed by: (1) Afforestation and controlled grazing (2) Proper management of watersheds (3) Leveling and terracing in mining areas (4) Biological and engineering treatments for eroded lands.
-
Q: What is the role of an individual in resource conservation?
A: An individual can: (1) Practice the 5 R's (Reduce, Reuse, Recycle, Refuse, Repurpose) (2) Use water and electricity judiciously (3) Use public transport/carpool (4) Plant trees (5) Create awareness about sustainability.
-
Q: Why are plateaus rich in mineral resources?
A: Plateaus are rich in minerals because they are ancient landmasses composed of igneous and metamorphic rocks formed by cooling of magma or under great heat and pressure. These processes lead to the concentration of minerals. Example: Chota Nagpur Plateau in India.
-
Q: What is the main takeaway from this chapter?
A: Resources are vital for survival and development, but they are finite and unevenly distributed. Their indiscriminate use leads to depletion and ecological crises. Therefore, Resource Planning and Sustainable Development are essential for balancing human needs with environmental protection for present and future generations.
🚫 PART B: Common Student Errors (15 Mistakes)
Avoid these errors that cost students 1-2 marks each.
Error 1: Confusing "Stock" and "Reserve". A Reserve is a subset of Stock that can be used with existing technology.
Error 2: Writing "All resources are gifts of nature" - Technology and human intervention are needed to turn natural substances into resources.
Error 3: Spelling "Sustainable Development" as "Sustainable Development".
Error 4: Saying "Laterite soil is good for agriculture" - It is low in fertility due to leaching, suitable mainly for cashews, tea, coffee with manure.
Error 5: Writing "Agenda 21 is a law" - It is a non-binding, voluntary action plan.
Error 6: Confusing Khadar (new, fertile) with Bhangar (old, less fertile).
Error 7: Stating "Black soil is found in Punjab" - It is predominantly found in the Deccan Trap region (Maharashtra, Gujarat, Madhya Pradesh).
Error 8: Mixing up causes of land degradation - attributing mining to Punjab (agricultural state) instead of Jharkhand/Chhattisgarh.
Error 9: Forgetting the third stage of Resource Planning (matching with national plans).
Error 10: Writing "Rio Summit was in 1990" - Correct year is 1992.
Error 11: Saying "Alluvial soil is only found in Northern Plains" - It is also found in coastal plains and river basins in Peninsular India.
Error 12: Using "Soil Conservation" and "Soil Erosion" interchangeably. Conservation is the solution, erosion is the problem.
Error 13: Misspelling geographical terms: "Laterite" not "Laterate", "Alluvial" not "Aluvial".
Error 14: Stating "India has abundant absolute resources" - India's per capita availability is low due to high population.
Error 15: In maps, incorrectly locating soil regions (e.g., placing Arid soil in Kerala instead of Rajasthan).
💯 PART C: Score-Saving Tips (10 Tips)
Implement these to gain 5-10 extra marks in board exam.
Tip 1: Always define key terms first in answer: "Resource Planning is..." or "Sustainable Development means..."
Tip 2: For "Classify/Distinguish" questions, use a tabular format or bullet points with clear headings.
Tip 3: Underline geographical terms: Khadar, Bhangar, Laterite, Agenda 21, Regur.
Tip 4: When giving examples, be specific: "e.g., Gully erosion in the Chambal basin (Ravines)" instead of just "gully erosion".
Tip 5: Map questions: Write the name + one key fact: "Location: Rajasthan - Arid Soil / Major cause of land degradation: Overgrazing."
Tip 6: For causes/effects/steps questions, use numbered points (at least 3-4) with brief explanations.
Tip 7: Link answers to current issues when possible: "Conservation is needed... as seen in recent water crises."
Tip 8: Use diagrams: Sketch a simple flowchart for Resource Planning stages or methods of soil conservation (contour ploughing).
Tip 9: In "Why" questions, structure answer: "Because... This leads to... Therefore..."
Tip 10: Conclude answers on a forward-looking note: "...thus, ensuring sustainable development for future generations."
