Question: What are potential resources? Give two examples.

Answer: Resources which are found in a region, but have not been utilized due to lack of capital or other reasons. For example, the western parts of India particularly Rajasthan and Gujarat have enormous potential for the development of wind and solar energy, but so far these have not been developed properly.

Question: What are developed resources? Give two examples.

Answer: These are resources which have been surveyed and their quality and quantity have been determined for utilization. The development of resources depends on technology and level of their feasibility. For example, India has a cumulative total of 2,47,847 million tones of coal resources.

Question: What is stock? Give two examples.

Answer: These are material in the environment which have the potential to satisfy the human needs but could not be used as the human beings do not have the appropriate technology to convert them into usable form. For example, water (H2O) is a compound of two inflammable gases i.e. hydrogen and oxygen but human beings do not have the required technology to use them as a source of energy.

Question: What are reserves? Explain with examples.

Answer: Reserves are the subset of the stock, which can be put into use with the help of existing technical ‘know-how’ but their use has not been started. These can be used for meeting future requirements. River water can be used for generating hydroelectric power but presently, it is being utilized only to a limited extent. Thus, the water in the dams, forests etc. is a reserve which can be used in the future.

  1. India has enormous diversity in the availability of resources. There are many regions which are rich in certain type of resources but are deficient in some other resources.
