Resources – Class VIII

Q1. What is resources?

Ans: Anything that can be used to satisfy a need is a resource. For example chair, table, blackboard etc. in the class or water, air, coal petroleum etc.
Q2. What are important factors of resource formation?
Ans: 
I) Time and technology are two important factors that can change substances into resources. Both are related to the needs of the people.
II) People themselves are the most important resource. It is their ideas, knowledge, inventions and discoveries that lead to the creation of more resources.
III) Each discovery or invention leads to many others. The discovery of fire led to the practice of cooking and other processes while the invention of the wheel ultimately resulted in development of newer modes of transport. The technology to create hydroelectricity has turned energy in fast flowing water into an important resource.
Q3. Discuss about the classification of resources.
Ans: 
● Resources are generally classified into natural, human made and human.
I) Resources that are drawn from Nature and used without much modification are called  natural resources. Like air soil etc.
II) Some resources are made by human, like- chair, table, building etc.
● On the basis of their development and use resources can be classified into two groups-
I) Actual resources:
Actual resources  are those resources whose quantity is known. Like coal, petroleum.
II) Potential resources:
Potential resources are those whose entire quantity may not be known and these are not being used at present. These resources could be used in the future.
● Based on their  origin, resources can be abiotic  or biotic. Abiotic resources are non-living while biotic resources are living.
● Natural resources can be broadly categorised into renewable  and  non-renewable  resources.
I) Renewable resources are those which get renewed or replenished quickly.
II) Non-renewable resources  are those which have a limited stock.
● On the basis of their distribution resources can be ubiquitous  or  localised.
I) Resources that are found everywhere like the air we breathe, are ubiquitous.
II) But those which are found only in certain places are localised, like copper and iron ore.
