Q.3. Describe any three ill effects of the overuse of resources. 

Ans. Ill- effects of the overuse of resources:

(i) Overuse of soil can cause infertility in many regions.

2. Human Resources: Human resources include those people who serve us as a teacher, as a doctor, as a cobbler, etc.

3. Human-made Resources: These resources are formed by human beings. Human beings forming these resources by using intelligence and knowledge eg. Buildings, roads, telephone etc. Natural resources can be classified as renewable and non- renewable sources which do not get replenished and can be used continuously are known as renewable resources e.g. water. Resources which get exhausted are known as non-renewable resources, e.g. coal, petroleum etc.

Resources may be actual and potential.

Resources whose total quality and quantity are known at present are known as actual resources and resources whose total available quantity is not known at present are known as potential resources.

On the basis of origin a resource can be abiotic or biotic. Abiotic resources are non-living eg. Rocks, metals etc. Biotic resources are living eg. fisheries etc.

On the basis of level of development resources can be Ubiquitous or Localized.

Localised resources are found in some parts of the world while ubiquitous are found everywhere.


Q.1. “Resources are function of human activities”. Explain.

Ans. Natural endowment of environment are nature’s free gift. But these become resources only when man utilize them. Human beings transform material available in our environment into resources. For example, wood is transformed into furniture by a carpenter. So human beings are essential components of resources.

(i) Physical process.

(ii) Chemical process.

(iii) Mechanical process.

Q.4. What are the different types of values resources may possess?

Ans. Resources may possess different values as:

(i) Economic Value: The resources (raw materials) which are used in the manufacture of other useful products have economic value e.g, means of irrigation, coal, petroleum.

(ii) Aesthetic Value: The high mountains, the waterfall, natural sceneries all have aesthetic value for us.
