Resources

 Q1) Differentiate between

     1)    Renewable & Non-Renewable resources

Ans:
·        Renewable resources are those that get regenerated or replenished rapidly . some resources replenish themselves ( like wild and forests ) and some can be replenished with the help of physical, chemical and mechanical processes.
·        Non-Renewable resources are those resources which cannot be replenished or renewed.
Some other resources like coal take thousands of years to get naturally replenished which is several times than the human’s life.

      2)    Potential resources and Actual or developed resources
·        Potential resources are those resources which could be of use in the future due to break through in technology or changing circumstances, Ex: biofuel and petroleum.
·        Actual or developed resources are resources which have already been developed and which are presently being used. The quality and quantity of these resources are known to us. The iron ore and coal deposits in Jharkhand, the petroleum deposits in West Asian countries, gold diamonds deposits in South Africa.

      3)    Ubiquitous resources and localized resources
·        Ubiquitous resources are resources which are found everywhere. Ex: air is a ubiquitous resource as it is found everywhere.
·        localised resources are those which are unevenly distributed across the world  and are only found concentrated in certain regions. Ex: Copper, iron ore, gold, diamonds and silver.

     4)    Biotic resources and abiotic resources
·        Biotic resources include all living organisms on the earth. the Flora( vegetation ) and the Fauna  ( animal life ). Human beings are biotic resources.
·        Abiotic resources are non-living substances used by human beings such as soil, air and sunlight.
Q2) What are resources? Explain in detail.

Ans:
A resource is anything that can be used to satisfy human wants.
Sources include:
·        Things which are present in the environment and which humans use directly.
·        Things which humans transform into usable material to satisfy their needs.
It is the utility of a product or service which makes it a resource. They transform it by using an appropriate technology and skills.
Q3)  How can we broadly classify resources

Ans:
Resources can be broadly classified into natural resources, human made resources and human resources.
-         Resources derived from nature are called natural resources. Air, water found in rivers, lakes and ponds, sunlight, soil, minerals, natural vegetation and wildlife are some examples of natural resources.
-         Human-made resources are those which humans create using technology and skills. Air crafts, machinery, buildings, roads and railway track are examples of human made resources.
-         Human resources consists of people themselves.

Q4) What are sustainable development?

Ans:
Sustainable development can be defines as development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

Q5) What are the four golden roles of conservation?

Ans:
The four golden R’s for conservation are :
Reduce: Consume less and do not waste.
Reuse: use a product or resource as many times as you can
Recycle: Avoid wastage by changing a product in another usable material
Refuse: If you do not need a thing refuse it.

Q6) What is human – made resources?

Ans:
Human – made resources are those which humans create using technology and skills.
 Ex: air crafts, machinery, buildings, roads and railway tracks.

Q7) “ Human wants are satisfied primarily by nature “. Justify this statement.

Ans:
Almost every need of man is satisfied primarily by nature. For food he has to depend on soil fertility to grow crops. For clothing he has to depend on plants.

Glossary:

Resource : anything that satisfies human needs.

Biotic resources: living resources like plants and animals.

Abiotic resources: non – living resources like air and water.

Renewable resources: something that get replenished

Ubiquitous resources: present everywhere .

Sustainable development: development that meets the needs of the present without damaging the environment.
