Resource, Geography

1. Resources & Wealth
•Meaning & concept of Resources & Wealth
•Types & Characteristics of Resources
•Alternative Resources
•Recycling & Conserving resources

2. Wealth
• Wealth is an abundance of
valuable material possessions or
resources.
• An individual, community, region
or country that has an abundance
of such possessions or resources
is called wealthy.

3. What is a resource?
• Naturally occurring material
• Useful to society
• Able to be exploited (used)
• Availability depends on:
–Physical characteristics of the
resource
–Economic and technological
condition of society

4. NONRENEWABLE
AND
RENEWABLE
RESOURCES

5. NONRENEWABLE RESOURCES
A nonrenewable resource is a natural
resource that cannot be re-made or
re-grown at a scale comparable to its
consumption.

6. NUCLEAR ENERGY
Nuclear fission uses
uranium to create
energy.
Nuclear energy is a
nonrenewable
resource because once
the uranium is used, it
is gone!

7. HOW IS COAL MADE ???

8. COAL, PETROLEUM, AND GAS
Coal, petroleum, and
natural gas are
considered
nonrenewable because
they can not be
replenished in a short
period of time. These
are called fossil fuels.

9. HOW ARE OIL AND GAS MADE ???

10. RENEWABLE RESOURCES
Renewable resources are
natural resources that can be
replenished in a short period
of time.
● Solar Geothermal●
● Wind Biomass●
● Water

11. SOLAR
Energy from the
sun.
Why is energy
from the sun
renewable?

12. WIND
Energy from
the wind.
Why is
energy from
the wind
renewable?

13. GEOTHERMAL
Energy from
Earth’s heat.
Why is energy
from the heat of
the Earth
renewable?

14. BIOMASS
Energy from
burning organic
or living matter.
Why is energy
from biomass
renewable?

15. WATER or HYDROELECTRIC
Energy from the
flow of water.
Why is energy of
flowing water
renewable?

16. Resource classification
• On the basis of origin, resources may be
divided into:
1)Biotic - Biotic resources are the ones which
are obtained from the biosphere. Forests and
their products, animals, birds and their
products, fish and other marine organisms
are important examples. Minerals such as
coal and petroleum are also included in this
category because they were formed from
decayed organic matter.
2)Abiotic - Abiotic resources comprise of non-
living things. Examples include land, water,
air and minerals such as gold, iron, copper,
silver etc.

17. On the basis of the stage of development, natural
resources may be called:
1)Potential Resources - Potential resources are
those which exist in a region and may be used
in the future. For example, mineral oil may
exist in many parts of Bangladesh having
sedimentary rocks but till the time it is actually
drilled out and put into use, it remains a
potential resource.
2)Actual Resources are those which have been
surveyed, their quantity and quality determined
and are being used in present times. For
example, the natural gas which is obtained
from the Bangladesh Fields.
3)Reserve resources: That part of the actual
resource which can be developed profitably
with available technology is called a reserve.

18. On the basis of renewability, natural resources
can be categorized into:
• Renewable Resources - are the ones which
can be replenished or reproduced easily like
sunlight, air, wind, etc., are continuously
available and their quantity is not affected by
human consumption.
• Many renewable resources can be depleted
by human use, but may also be replenished,
thus maintaining a flow. Some of these, like
agricultural crops, take a short time for
renewal; others, like forests, take even
longer.

19. • Non-renewable Resources - are formed over
very long geological periods. Minerals and
fossils are included in this category. Since
their rate of formation is extremely slow,
they cannot be replenished once they get
depleted.
• Out of these, the metallic minerals can be
re-used by recycling them. But coal and
petroleum cannot be recycled.
• On the basis of ownership, resources can
be classified into:
• Individual, community, national, and
international resources:

20. Human Resources
• Human resources are man
and his mind
• Human resources depend on
level of education, skilled or
unskilled labor, and are
entrepreneurial or have
managerial abilities.

21. Capital Resources
• Capital resources are resources
that can be used to make more,
like money or tools key features of
capital are the availability of money
for lending, the level of
infrastructure, the availability and
use of tools, machines, and
technologies

22. Energy resources and technology
has changed over time
• Wood--deforestation
• Coal--pollution, mining problems,
competition with oil and gas
• Petroleum--transportation,
environmental considerations
• Nuclear--contamination, waste
• solar or wind--cost, aesthetics

23. Examples of technology creating
demand
• Some new technologies have
created a demand for a particular
natural resource--steam engine and
coal, internal combustion engine
and gas, computer chips and
skilled labor

24. Costs and benefits from using
natural resources
Benefits
1.Helps us produce goods and
services.
2. It creates employment
opportunities
3. It helps develop new technologies

25. Costs and benefits from using
natural resources
Costs
1. Resource depletion.
2. Environmental destruction
3. Health problems

26. The effects of unequal
distribution of resources
Because resources are distributed
unequally around the world, it
causes several things to happen
1. Interdependence of nations --
they must trade with each other to
acquire the goods they do not
possess

27. The effects of unequal
distribution of resources
2. Uneven economic development
(rich and poor countries)
3. Energy producers and consumers
4. Imperialism (one country
dominating another)
5. conflicts over control of resources

28. Differences between developing
and developed nations
• Developed nations have
better access to natural and
capital resources
• Developed nations have
more investment in
technology and have created
a better infrastructure

29. Differences between developing
and developed nations
• Developed nations have more
skilled labor
• Developed nations have a higher
level of economic development
• Developed nations have a higher
standard of living and a higher
quality of life

30. Conservation of resources
• Earth's natural resources are either
nonrenewable, such as minerals, oil, gas, and
coal, or renewable, such as water, timber,
fisheries, and agricultural crops.
• The combination of growing populations and
increasing levels of resource consumption is
degrading and depleting the natural resource
base.
• Management of the human use of natural
resources to provide the maximum benefit to
current generations while maintaining
capacity to meet the needs of future
generations.
• Conservation includes both the protection
and rational use of natural resources.

31. Conservation of resources
• Nonrenewable resources, such as fossil
fuels, are replaced over geologic time
scales of tens of millions of years.
• Human societies will eventually use up
all of the economically available stock
of many nonrenewable resources, such
as oil.
• Conservation entails actions to use
these resources most efficiently and
thereby extend their life as long as
possible.

32. Conservation of resources
• By recycling aluminum, for
example, the same piece of
material is reused in a series of
products, reducing the amount of
aluminum ore that must be mined.
• Similarly, energy-efficient products
help to conserve fossil fuels since
the same energy services, such as
lighting or transportation, can be
attained with smaller amounts of
fuel.
