Q1. What are resources?

Answer:
All the things around us that are useful and fulfil our needs are called resources.

Q2. Why are resources unevenly distributed?

Natural resources are those which come from nature like water, soil, minerals, trees and animals.

Q4. What are the two types of natural resources?

Answer:
Natural resources are of two types:

  1. Renewable – air, water
  2. Non-renewable – coal, petrol

Q5. What are human-made resources?

Answer:
Human-made resources are those which humans make like machines, roads, buildings, vehicles and technology.

Q6. What are human resources?

Answer:
Human resources are humans themselves — their knowledge, skills, education and abilities.

Q7. What are biotic and abiotic resources?

Answer:
Biotic resources are from living things like plants and animals.
Abiotic resources are from non-living things like soil, water and minerals.

Q8. What are actual resources?

Answer:
Actual resources are those whose quantity is known and are used right now.

Q9. What are potential resources?

Answer:
Potential resources are those which may be used in the future and are not used at present.

Q10. What is sustainable development?

Answer:
Sustainable development means using resources so that today’s needs are met and resources are saved for the future.


1. What are Resources? (Definition)

All the things around us that are useful and fulfil our needs are called resources.
Examples: water, soil, trees, minerals, machines, humans, etc.

2. Why are Resources Unevenly Distributed?

Because every place has different:
✔ Climate
✔ Soil
✔ Height
✔ Temperature
So, resources are not the same everywhere.

3. Major Types of Resources (3 Types)

(1) Natural Resources (Come from Nature)

Examples: water, soil, minerals, trees, animals
Two types:

  1. Renewable (can be replaced) – air, water
  2. Non-renewable (cannot be replaced quickly) – coal, petrol

(2) Human-made Resources

Made by humans
Examples: machines, roads, buildings, vehicles, technology

(3) Human Resources

Humans themselves
Human knowledge, skills, education, abilities
Humans use natural resources properly.

4. Biotic and Abiotic Resources

Biotic: From living things — plants, animals
Abiotic: From non-living things — soil, water, minerals

5. Actual and Potential Resources

Actual Resources:
– Quantity is known
– Used right now
Examples: petroleum of Gulf countries, coal of Jharkhand

Potential Resources:
– May be used in the future
– Not used at present
Examples: uranium in Ladakh, monazite in Kerala

6. Ubiquitous and Localised Resources

Ubiquitous: Found everywhere → air, sunlight
Localised: Found only in specific places → coal, iron, bauxite, monazite

7. Renewable and Non-renewable Resources

Renewable:
– Can be quickly replaced by nature
→ air, sunlight, water

Non-renewable:
– Once used, cannot be replaced soon
→ coal, petrol, natural gas

8. Resource Conservation

Using resources carefully and not wasting them is called resource conservation,
so that future generations can also use them.

9. Why is a Human Being a Resource?

Because humans can
✔ think
✔ learn
✔ create new technology
✔ use resources wisely

10. Sustainable Development

Using resources in such a way that
✔ today's needs are met
✔ resources are saved for the future

Includes:

  1. Protecting the environment

संसाधन 8th

-
  🌟  🔶 1. संसाधन क्या हैं? (परिभाषा) हमारे आसपास मिलने वाली वे सभी चीजें जो उपयोगी हों और हमारी जरूरतें पूरी करें — संसाधन कहलाती हैं। जैसे— पानी, मिट्टी, पेड़, खनिज, मशीन, मनुष्य आदि। 🔶 2. संसाधन क्यों असमान रूप से मिलते हैं? क्योंकि हर जगह का ✔ जलवायु ✔ मिट्टी ✔ ऊँचाई ✔ तापमान अलग–अलग होता है। इसलिए संसाधन हर जगह एक जैसे नहीं होते। 🔶 3. संसाधनों के प्रमुख प्रकार (3 Types) (1) प्राकृतिक संसाधन (Nature से मिलते हैं) – उदाहरण: पानी, मिट्टी, खनिज, पेड़, जानवर – दो प्रकार: नवीकरणीय (फिर बन जाते हैं) – हवा, पानी अनवीकरणीय (जल्दी नहीं बनते) – कोयला, पेट्रोल (2) मानव निर्मित संसाधन (Man-made) – जो मनुष्य बनाता है – उदाहरण: मशीन, सड़क, इमारत, वाहन, तकनीक (3) मानव संसाधन (Human Resource) – स्वयं मनुष्य – मनुष्य का ज्ञान, कौशल, शिक्षा, क्षमता – मनुष्य प्रकृति के संसाधनों का सही उपयोग करता है। 🔶 4. जैव और अजैव संसाधन जैव (Biotic) : जीवित चीजों से — पेड़, पौधे, जानवर अजैव (Abiotic) : निर्जीव चीजें — मिट्टी, पानी, खनिज 🔶 5. वास्तविक (Actual) और ...
