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.
