4. What are human resources?
Answer: Human resources refer to people and their skills, knowledge, and abilities that contribute to the development of resources.
5. What is the difference between renewable and non-renewable resources?
Answer:
Renewable resources
can be replenished naturally over time (e.g., Solar energy, Wind energy).
Non-renewable resources
are limited and cannot be replaced quickly (e.g., Coal, Petroleum).
6. What are biotic and abiotic resources?
Answer:
Biotic resources
are obtained from living organisms (e.g., Forests, Animals).
Abiotic resources
come from non-living things (e.g., Water, Minerals).
7. Give two examples each of localized and ubiquitous resources.
Answer:
Localized resources
(found only in specific places): Gold, Petroleum.
Ubiquitous resources
(found everywhere): Air, Sunlight.
8. What is sustainable development?
Answer: Sustainable development is using resources wisely to meet present needs without compromising the needs of future generations.
9. Why is conservation of resources important?
Answer: Conservation is important to ensure resources are available for future generations, prevent environmental degradation, and maintain ecological balance.
10. What do you mean by the term "patent"?
Answer: A patent is an exclusive right granted to an individual or company over an invention or a unique product, preventing others from using it without permission.
11. How does human intervention help in resource development?
Answer: Humans modify natural resources using technology, skills, and knowledge to make them more useful. For example, crude oil is refined into petrol and diesel.
12. How is technology an important factor in resource development?
Answer: Technology helps in improving the efficiency of resource utilization, discovery of new resources, and conservation of existing resources.
13. Mention any three factors that affect the distribution of resources.

(e.g., Public parks, Lakes)
National resources
(e.g., Forests, Railways)
International resources
(e.g., Oceanic resources, Antarctica)
15. What is resource planning?
Answer: Resource planning is the process of managing the use of resources in an efficient and sustainable way to prevent overuse or depletion.
16. What are potential resources? Give an example.
Answer: Potential resources are resources that are not currently used but have potential for future use. Example: Wind energy in coastal areas.
17. How can resources be classified based on their origin?
Answer:
Biotic resources
– Derived from living things (e.g., Plants, Animals).
Abiotic resources
– Derived from non-living things (e.g., Air, Rocks).
18. What are the different types of resources based on availability?
Answer:
Renewable resources
(e.g., Water, Solar energy)
Non-renewable resources
(e.g., Coal, Natural gas)
19. How can we conserve water resources?
Answer:
Rainwater harvesting
Using water efficiently
Preventing water pollution
20. What is the role of education in human resource development?
Answer: Education improves knowledge, skills, and productivity, making individuals more capable of using and managing resources effectively.
21. What are stock resources? Give an example.
Answer: Stock resources are those that have potential but lack technology for use. Example: Hydrogen as a fuel.
22. How can we conserve fossil fuels?
Answer:
Using alternative energy sources (solar, wind)
Reducing fuel wastage
Promoting energy-efficient appliances
23. What do you understand by the term "community-owned resources"?
Answer: Community-owned resources are resources that are accessible and used by all members of a community, such as parks, grazing lands, and rivers.
