Question 1.
What do you understand by a ‘Resource’? Give examples. (2015)
Answer:
Everything available in our environment which can be used to satisfy our needs, is called a resource. It should be technologically accessible, economically feasible and culturally acceptable. Only then, it can be termed as a ‘Resource’. Examples are: minerals, forests, fossil fuels etc..
Question 2.
“Resources are a function of human activities.” Justify this statement.
Answer:
Mere presence of resources, as free gifts of nature, does not make them resources. Human beings are essential components of resources because they transform material available in our environment into resources. The utility of resources depends on the stage of cultural development of man and the tools and technology used by him.

(a) On the basis of Origin:
Biotic
Abiotic
(b) On the basis of exhaustibility:
Renewable
Non-renewable
(c) On the basis of ownership:
Individual (Personal)
Community
National
International
(d) On the basis of status and development:
Potential
Developed
Reserve
Stock
Question 4.
Explain the classification of resources on the basis of origin and give one example of each.
Answer:
On the basis of origin, resources can be classified as Biotic and Abiotic.
Biotic Resources are obtained from the biosphere. They have life or are living resources, e.g., human beings, fisheries, forests, etc.
Abiotic Resources include all non-living things, e.g., rocks and minerals.
Question 5.
Classify the resources on the basis of exhaustibility and give two examples of each.
Answer:
On the basis of exhaustibility, resources can be classified as: Renewable and Non-renewable.
Renewable Resources. The resources which can be renewed or reproduced by physical, chemical and mechanical processes are known as renewable or replenishable resources, e.g., water, wildlife, forests, solar energy, wind energy etc.
Non-renewable Resources. The resources which once get exhausted, cannot be remade. They take a long geological period of time, i.e., millions of years in their formation, e.g., minerals, fossil fuels etc.
Question 6.
Write two types of renewable resources and give one example of each type.
Answer:
Two types of renewable resources are as follows:
Continuous or Flow Resources, e.g., wind and water resources.
Biological Resources, e.g., natural vegetation (forests) and wildlife.
Question 7.
Write two characteristics of non-renewable resources and write their two broad categories with examples.
Answer:
Two characteristics of non-renewable resources:
They cannot be recycled and get exhausted with their use.
They take millions of years in their formation.
Two broad categories of non-renewable resources:
Recyclable resources, e.g., metals.
Non-recyclable resources, e.g., fossil fuels.
Question 8.
Give any two examples of non-renewable resources. (2015)
Answer:
Non-renewable resources are resources which once get exhausted, cannot be remade. They take a long geological period of time, i.e., millions of years, in their formation, e.g., minerals, fossil fuels,
Answer:
1. all the thing on earth which are necessary for our exitence on this planet are known as resources.Ex -water, coal.
2.resources which are obtained from biosphere and have life are known as biotic resources.Ex-animal, fish ,forest.
3.A resource that is available in a country which is not fully trapped are known as potential resourcesEx,-petroleum
7. sustainable development means development that takes at place without damaging the environment.
