Natural resources are all aspects of the natural environment that exist independently of human actions, including forests, water, minerals, land, and energy sources. Forest resources provide conservation of soil, reduction of pollution, and control of water flow. Mineral resources include fuel minerals like coal, oil and natural gas which account for most mineral production value, as well as metallic and non-metallic minerals. Water resources are vital for life and are used for agriculture, industry, households, and energy generation. Land resources occupy 20% of the earth's surface and provide areas for housing, roads, and factories. Energy resources include thermal, chemical, mechanical, nuclear, solar, and electrical energy and can come from primary renewable sources or secondary sources derived

2. Natural ResourcesNatural Resources are all that exists without the
actions of humankind. This includes all natural
characteristics such as magnetic, gravitational, and
electrical properties and forces.
A natural resource may exist as a separate entity
such as fresh water, and air, as well as a living
organism such as a fish, or it may exist in an
alternate form which must be processed to obtain the
resource such as metal ores, oil, and most forms of
energy.

4. FOREST RESOURCES
• Introduction
• Use and over exploitation

5. FOREST RESOURCES
INTRODUCTION: In India, forests form 23 percent of the
total land area. The word ‘forest’ is derived from the Latin word
‘foris’ means ‘outside’.
A forest is a natural, self-sustaining community
characterized by vertical structure created by presence of
trees. Trees are large, generally single-stemmed, woody
plants.
A forest is a collection of past responses to
outside influences and internal competitive interactions.
Therefore, the present status of any forest, indeed of any
natural community, reflects what has gone on before.

6. Use and Over Exploitation:
A forest is a biotic community predominantly
of trees, shrubs and other woody vegetation, usually with a
closed canopy. This invaluable renewable natural resource is
beneficial to man in many ways.
(a) Conservation of Soil: Forests prevent soil erosion by binding the
soil with the network of roots of the different plants and reduce the
velocity of wind and rain — which are the chief agents causing
erosion.
(b) Reduction of Atmospheric Pollution: By using up carbon
dioxide and giving off oxygen during the process of
photosynthesis, forests reduce pollution and purify the
environment.
(C)Control of Water flow: In the forests, the thick layer of humus
acts like a big sponge and soaks rain water preventing run-off,
thereby preventing flash-floods. Humus prevents quick
evaporation of water, thereby ensuring a perennial supply of
water to streams, springs and wells.

7. MINERAL RESOURCES
Definition: Minerals provide
the material used to make
most of the things of
industrial- based society;
roads, cars, computers,
fertilizers, etc.

8. Types of Mineral Resources:
Minerals in general have been
categorized into three classes’ fuel, metallic and non-
metallic. Fuel minerals like coal, oil and natural gas have
been given prime importance as they account for nearly
87% of the value of mineral production whereas
metallic and non-metallic constitutes 6 to 7%.

9. WATER RESOURCES
• Introduction
• Uses

10. Water is one of the most vital natural
resources for all life on Earth. The
availability and quality of water
always have played an important
part in determining not only where
people can live, but also their quality
of life. Even though there always has
been plenty of fresh water on Earth,
water has not always been available
when and where it is needed, nor is
it always of suitable quality for all
uses. Water must be considered as a
finite resource that has limits and
boundaries to its availability and
suitability for use.

11. Uses Of Water
 Agricultural needs
 Industrial Needs
 House Hold Needs
 Energy Generation
Water is the most amazing thing on the
earth.It has many uses as follows

12. Land Resources
They occupy nearly 20 percent of the earth surface. It
covers around 13000 million hectares of the area. The
houses, roads and factories occupy nearly one third of the
land.
The soil is defined as a natural body which keeps on
changing and allows the plants to grow.

18. Energy Resources
Energy may be defined as the capacity to do work. In today’s
world development is impossible without energy. Life is
unthinkable without energy. Both energy production and energy
utilization are the indicators of a country’s progress as it is a
primary input for industrial operation.

19. • Thermal energy
• Chemical energy
• Mechanical energy
• Nuclear energy
• Solar energy
• Electrical energy

20. • Energy Relating to or
associated with heat
Mechanical energy
• The kinetic and potential energy
considered together
Thermal energy

21. Chemical energy
• That part of the energy in a substance that
can be released by a chemical reaction
Electrical energy
• Energy made available by the flow of
electric charge through a conductor

22. Nuclear energy
• Energy produced by fusion or fission
of the nuclei of an atom or simply the
energy released by a nuclear reaction
Solar energy
• Energy radiated by the sun.

23. Primary Energy Resources
• Renewable/Inexhaustible/Non-Conventional sources of
energy.
• Example : Wood, Solar energy etc
Secondary Energy Resources
• Does occur in nature but are derived from primary
energy sources
• Example: Petrol, Hydrogen obtained through
electrolysis of water etc.
