Chapter 1- Resources

 

 

Q. What are  resources? 

Ans:- Anything that can be used to to full fill  a need is called a resource, such as water, soil,  forests, minerals, buildings, roads etc. usability makes  an object or substance a resource.

Q. How does something become a resource?

Ans:- when something is  use at mass level that  gives it a value. All resources do not have same value. Some resources have economic value, some do not. For  example, metals may have an economic value, a beautiful landscape may not. But both are important and satisfy human needs.  Time and technology are two important factors that can change substances or a thing into resources. 

Q. what are the different Types of Resources?

Resources are generally classified into natural, and Man Made

(A) Natural Resources: 

 Resources  that  are  obtained  from  Nature  and  used  without much  change  are  called  natural resources. The air we breathe, the water in our rivers and lakes and oceans(water resource), the soils, minerals are all natural resources. Many of these resources are free gifts of nature and can be used as  directly. 

Natural resources can be broadly categorised into renewable and non renewable resources. 

(1) Renewable resources are those which get renewed or replenished quickly.   Some of these are unlimited and are not affected by human activities, such as  solar and wind energy. 

(2) Non-renewable resources are those which have a limited stock.  Once  the  stocks are exhausted it  may take  thousands of  years  to  be  renewed  or   replenished. Coal, petroleum and natural gas are some examples. 

 Distribution of Resources: 

The distribution of natural resources depends upon number of physical factors  like terrain, climate and altitude. The distribution of resources is unequal  because these factors  differ on the surface of   earth. 

(B) Man  Made Resources :- 

Sometimes, natural substances become resources  only when their original form has been changed by the intervention of man . Iron ore was not a resource until  man  learnt to extract iron from it. People use natural resources to make  buildings, bridges, roads, machinery and vehicles, which are known as man   made resources. Technology is also a man made resource. 

(C) Human Resources: 

People can make the best use of nature to create more resources when they have  the knowledge, skill and the technology to do so. That is why human beings are a  special resource.  People are called human resources. Education and health help in making people a valuable resource. 

Human Resource refers to the number (quantity) and abilities (mental and  physical) of the people. Though, there are differing views regarding treatment of humans as a  resource, one cannot deny the fact that it is the skills of human that help in  transferring the physical material into a valuable resource.  Improving  the quality  of people’s skills  so that they are able to create more   resources is  known as human resource development. 

Q . Conserving Resources  And Sustainable Development 

Using resources judiciously and giving them time to get renewed or replenish is  called.   resource conservation.  Balancing the need to use resources and also conserve them for the future is  called sustainable development. 

Sustainable Development: 

Carefully utilising resources so that besides meeting the requirements of the  present, also takes care of future generations.  There are many ways of conserving resources. Each person can contribute by  reducing consumption, recycling and reusing thing (3 R’s). Ultimately it makes  a difference because all our lives are linked. 

Some Principles of Sustainable Development: 

➡Respect and care for all forms of life 

➡ Improve the quality of human life 

➡ Conserve the earth’s vitality and diversity 

➡ Conserve the depletion of natural resources 

➡ Change personal attitude and practices towards the environment 

➡ Enable communities to care for their own environment. 

 

TEXT BOOK  TYPE QUESTIONS

1. Answer the following questions:

(i). Why are resources unequally distributed over the earth?

Ans. The distribution of natural resources depends upon a number of physical factors like terrain, climate and altitude. And these factors are not same everywhere and vary from place to place on the earth. Hence we find the distribution of resources unequal over the earth.

(ii). What is the resource conservation?

Ans. Using resources carefully and giving them. time to get renewed is called resource conservation.

 

(ii) Why are human resources important?

Ans. People are human resources and human resources are important because people can make the best uses of nature to create more resources by applying knowledge, skill and technology.

(iv) What is sustainable development?

Ans. Balancing the need to use resources and also conserve them for the future is called sustainable development. In other words, carefully utilizing resources so that besides meeting the present requirements it also takes care of the need of future generations is what is known as sustainable development.
