The document discusses natural resources and their classification. It defines natural resources as materials or substances found in nature that can be used for economic gain. Natural resources are classified as renewable resources, which can regenerate over time, and non-renewable resources, which cannot be regenerated or only regenerate slowly. Examples of renewable resources include solar, wind, and hydro energy. Non-renewable resources include fossil fuels like coal, oil, and natural gas. The document also discusses different types of natural resources like water, forests, minerals, and their importance. It notes that conservation of natural resources is important to ensure their sustainable use and prevent pollution and depletion.

Natural resources types and its uses.
1. If You can’t be in awe of mother nature, there’s
something wrong with you.
1
2. Material or Substances in nature which can be EXPLOITED for economic gain.
Natural Resources are resources that exists WITHOUT ANY ACTION of human
kind.
Natural Resources refers to the things that exists freely in nature for human use
and don’t necessarily need the action man kind for their generation and production.
Natural resources includes air, forests, animals, fish, marine life, biomass, fossil
fuels, renewable energy source like solar energy, wind energy, biomass energy,
geothermal energy etc.
Prosperity of a Nation is Dependent on the natural resources available
in the Nation.

6. Renewable Resources are those resources which can be REPLENISHED OR
RENEWED naturally over time.
Renewable energy is energy which is generated from natural resources i.e.
sun, wind, rain, tides, and can be generated again and again as and when
required.
They are available in plenty and by far most the Cleanest Sources of energy
available on this planet
Solar Energy, Wind Energy, Geo Thermal Energy, Biomass Energy From Plants,
Tidal Energy are the examples of renewable energy.
RENEWABLE NATURAL RESOURCES

8. NON RENEWABLE RESOURCES
Non renewable resources is a natural resource that THAT CANNOT BE
REMADE OR REGROWN at a scale comparable to its consumption.
Non-renewable sources are not Environmental Friendly and can have
serious effect on our health.
They are called non-renewable because they cannot be
regenerated within a short span of time.
Non-renewable sources exists in the form of fossil fuels, natural gas, oil
and coal.

9. A Book “Chandogya Upanishad”, thousand of years
old says, “Water is the essence of the earth and
plants are essence of water.”
A forest is a large area dominated by trees.
A large area of land covered with trees and plants, usually larger than a
wood, or the trees and plants themselves.
The forest is a complex ecosystem consisting mainly of trees that
buffer the earth and support a myriad of life forms.
There are approximately 1.2 billion hectares of open wood land
and Savanna and nearly 2.5 billion hectares of closed forest.
FOREST RESOURCES

10. We depend on forests for our survival,
from the air we breath to the wood we
use. Besides providing habitats for
animals and livelihoods for humans,
forests also provides watershed
protection, prevent soil erosion and
mitigate climate change.
Forests are vital to the ecological
functioning of the planet, producing 60
percent of the net productivity of all
terrestrial ecosystem.
They form the habitat for a large
portion of the earth’s plant and animal
species, providing the basis for the
biodiversity which is essential for the
biosphere’s future.

31. WATER RESOURCES
• Water resources are natural
resources of water that are potentially useful.
• All living things require water to grow and
reproduce.
• Its Uses
include agricultural, industrial, household,
• recreational and environmental activities
31
33. Salt Water
• Saline Water or salt water
is water with salt in it. It
often means the water from
the seas and oceans. Almost
all the water on Earth is
saline.
• Drinking Sea water alone is
dangerous.
Surface Water
• Surface water is water on
the surface of the planet,
above the ground. It is the
water
in rivers, lakes, wetlands and
oceans. It is different
to groundwater, which is in
the soil, and atmospheric
water, which is in the sky.
33
34. Frozen
Water
• Frozen water are those
which liquid or water that
turns into solid state when
its temperature is lowered
below its freezing point.
• In
contrast, solidification is a
similar process where a
liquid turns into a solid,
not by lowering its
temperature, but by
increasing the pressure
that it is under.
Ground
water
• Groundwater flow through
aquifers
• Groundwater is water located
below the ground surface.
Groundwater starts as rain and
flows under ground for long
periods of time
through aquifers.
• Groundwater flow returns to
the surface again
through springs and rivers.
Groundwater is an important
part of the water cycle.

37. Pollution
Marine Water
Marine pollution occurs
when harmful effects result
from the entry into
the ocean of chemicals,
particles, industrial,
agricultural, and residential
waste, noise, or the spread of
invasive organisms. ... Land
and air pollution have proven
to be harmful to marine life
and its habitats.
Ground Water
Groundwater
contamination occurs when
man-made products such as
gasoline, oil, road salts and
chemicals get into
the groundwater and cause it
to become unsafe and unfit
for human use.
