Samacheer Class 6 Social Science - Resources

Tertiary activities are basically concerned with the distribution of primary and secondary products through a system of transport and trade.
(e.g.) Banking, Trade, and Communications.
D. Give brief answers for the following

Development is necessary without affecting the needs of future generations.
If the present needs of resources are met and the conserving of resources for the future is balanced, we call it sustainable development.
E. Give short answers to the following questions

National resources
National resources are resources within the political boundaries and oceanic areas of a country.
Eg. Tropical Forest Region of India
International resources
International resources are all oceanic resources found in the open ocean. Resources found in the region can be utilized only after an international agreement.
Eg. Ambergris.

Man-made resources
Natural resources are modified or processed by technology into man-made resources.
Eg. Sugarcane processed to get Sugar
All structures built by man can also be called man-made resources.
Eg. Bridges, Houses, Road.
Human Resources
Human resources are groups of individuals who use nature to create more resources.
Through human beings are basically natural resources, we classify human beings separately.
Education health knowledge and skill have made them a valuable resource.
Eg. Doctors, Teachers, Scientists.

Mahatma Gandhi blamed “human beings” for the depletion of resources because of
overexploitation of resources
Unlimited needs of human beings. So, conservation is very important.
F. Give detailed answers to the following questions. (100 – 120 words)

Natural resources are classified according to theirs.
Origin
Development
Renewability
Distribution
Ownership
Question I.
On the basis of origin – Biotic Resources and Abiotic Resources
All living resources are Biotic resources. Example: Plants, Animals, Microorganisms.
Non-living resources are abiotic resources. Example: Land, Water, Air, Minerals
Question II.
On the basis of development – Actual Resources and Potential Resources
The resources that are being used at present are Actual resources. The quantity is known. Example: Coal at Neyveli.
The resources that are not utilized at present are potential resources. The quantity and location are not known.
Example: Marine yeast (in the Bay of Bengal and the Arabian Sea)
Question III.
On the basis of Renewability – Renewable Resources and Non – renewable Resouces?
After consumption, resources can be renewed with the period of time is called renewable resources. Example: Air, Water, Sun Light
Natural resources that have limited stock are non – renewable resources. Example: Coal, Petroleum, Natural gas, Minerals

Careful use of resources is the conservation of resources.
Due to the rapid increase in population the resources are being utilized at a very fast rate.
To avoid this we need sustainable development. Sustainable development can take place when
Wastage and excess consumption is prevented
Reusable resources are recycled
Pollution is prevented
Environment is protected
Natural vegetation and wildlife are preserved.
The easiest way to conserve resources is to follow the “3R”s: Reduce, Reuse, and Recycle.

The technique or skill of proper utilization of resources is Resource Planning. Resource Planning is necessary because
Resources are limited and we have to use them properly. Also, we have to save the resources for our future generation.
Resources are unevenly distributed over the different parts of the world.
It is also essential for the production of resources to protect them from overexploitation.
