Long Answer Questions
Q3. Write a note on the classification of resources.
Ans: Classification of Resources:
Natural Resources:
1. On the basis of Origin of Resources:
(a) Biotic (b) Abiotic
(a) Biotic Resource: All living things are known as Biotic Resources. These resources are obtained from the Biosphere and they have life, such as – Human Beings, Flora, Fauna, fisheries, etc.
(b) Abiotic Resource: All non-living things are known as Abiotic Resources, such as Wind, Water, Air, Rocks, Metals, etc.
2. On the basis of Exhaustibility or Utility of Resources:
(a) Renewable (b) Non-Renewable
(a) Renewable Resource: Resources which can be renewed or reproduced are known as Renewable Resource. E.g. Solar & Wind energy, Water, etc. Resources like Wind, Sunlight, are present in such huge quantities that human consumption does not effect them.
Many resources are replenishable which means these resources are recycled within the environment by natural process and their quantities remain constant. E.g. Oxygen Cycle and Water Cycle take place rapidly, whereas e.g. like Rock Cycle is very slow.
(b) Non-Renewable Resource: Resources get exhausted when used. These resources cannot be renewed or reproduced. Fossil Fuels like, coal, petroleum, natural gas are the best examples of non-renewable resource. These resources are limited in supply and it takes millions of years in their formation.
Metals like Gold, Silver, Copper and Iron are recyclable.
3. On the basis of Stage of Development of Resources:
(a) Actual Resource (b) Potential Resource
(a) Actual Resource: Resources whose existence has been proved and whose quality, quantity and location has been determined for utilization with the available technology. E.g. Assam oil fields, Damodar coal fields, etc.
(b) Potential Resource: Resources which are found in a region but have not been utilized, might be because of the lack of technology. They can be used in future. E.g. Solar and Wind are potential resource. Rajasthan and Gujarat have great potential for the development of these two resources.
Largest Solar Plant in India - Madhapur, Bhuj (Kutch, Gujarat)
Largest Wind farm cluster in India – Nagercoil (Tamil Nadu)
4. On the basis of Distribution of Resources:
(a) Ubiquitous (b) Localised
(a) Ubiquitous Resource: Resources which are found everywhere are called ubiquitous resource. E.g. air, land, water, etc.
(b) Localised Resource: Resources which are found only in certain places are localised resources, like coal, petrol, iron, etc.
5. mission of the international authorities. E.g. Minerals, fisheries, etc.
