5. INTRODUCTION
These are such material which
present in our natural environment
and useful to living organisms.
Ex : earthly life living beings etc..
All the components are
mixed to form a biosphere.

6. Biosphere
Abiotic Biotic
Abiotic : The matter such as water
,soil ,land ,air ,coal ,petroleum etc…
Biotic : Material such as human
beings ,animals ,pants & trees etc…

7. The Natural Resources may be
physical or biological resources…
Physical Resources : The resources
such that water ,soil ,land ,air ,coal
petroleum etc…
Biological Resources : Material
such as human beings ,animals
pants & trees etc…

8. Classification of Natural resources
Natural
resources
Exhaustible
Renewable
Non -
Renewable
Inexhaustible

9. Inexhaustible Resources: These are
present in unlimited quantity in nature
and not likely to be exhausted by
human activity or use.
For example
Solar energy
Air
Water

10. Exhaustible Resources: These are
present in limited quantity and
supposed to be finished by human
activity and uses.
For example:
Coal
petroleum
Mineral

11. Exhaustible Resources Are Categorized
Into Two Groups:
Renewable Resources: If once lost and
can be replaced when managed wisely.
For example
Agriculture
Aquatic Life
Wild Life

12. Non – Renewable Resources :
If once used or lost for ever as they
can never be restored.
For example
Fossil fuels
Metallic minerals
Natural gases

13. The Breath Of Life : Air
Air is a mixture of many gases like
nitrogen, oxygen, co2 and water vapors.
All living beings need oxygen to break
down glucose molecules and get energy for
their activities.
This results in the production of carbon
dioxide.

14. The Movement Of Air: Winds
These phenomena are the result of
changes that take place in our
atmosphere due to the heating of air
and the formation of water vapor.
Rain
When water bodies are heated during
the day, a large amount of water
evaporates and goes into the air.

15. Components of Air
COMPONENT PERCENTAGE
Nitrogen (N2) 78.08%
Oxygen (O2) 20.94%
Carbon dioxide (Co2) 0.03%**
Argon 0.91%
Trace component* 0.04%

16. Air Pollution
Adding unwanted substance.
 By human activities ,some natural
disasters or natural activity etc..,
Causes physical ,
biological imbalance of
atmosphere.

17. Oxygen Cycle
The oxygen cycle is the biogeochemical cycle
that describes the movement of oxygen within
and between its three main reservoirs: the
atmosphere (air), the biosphere (living things),
and the lithosphere (earth’s crust). The main
driving factor of the oxygen cycle is
photosynthesis, which is responsible for the
modern Earth's atmosphere and life.

18. Water : A Wonder Liquid
Water is one of the most important
part of our life.
It is important for metabolic reactions.
It is present in only 2.7% as fresh
water and 0.7 is
ground water.

19. Water Pollution
Combination of undesirable substance.
It makes water unfit for usage.
Dirty water mixed in rivers ponds,
oceans etc…
Various harmful substances make
water poisonous.

20. Rain Water Harvesting
It is a technique used to capture the
water or to use in lack of rain.
It is not beneficial for rich but it is for
all the annual rain fall in all over
India is 1200mm .
Then lack of water may be occur any
time so it is better to be prepared.

21. Water Cycle
It is also known as the hydrologic cycle.
Describes the continuous movement of
water on above and below the surface of
the earth.
Water can change states
among liquid, vapor and
ice during the water cycle.

22. Soil : Mineral Riches
About 1/5th part of earth’s surface is
under soil Land.
It consist of mineral matter ,organic
matter ,water ,air ,living organisms.
It is divided by
horizon as A
B ,C ,D Etc….

23. The Factors That Make Soil
 The Sun: The Sun heats up rocks during
the day so that they expand.
 Water: Water helps in the formation of
soil in two ways.
 Wind: Water rubs against rocks and
wears them down, strong winds also
erode rocks down.

24. Types Of Soil And Its Composition
s. no. Type of soil composition
1. Black soil Main constituent is clay.
2. Red soil Sandy loam soil.
3. Desert soil Sandy soil.
4. Mountain soil Gravel and sandy soil.
5. Alluvial soil Loamy ,clay soil.
6. Laterite soil Porous clay soil.

25. Soil Pollution
The contamination of soil with solid
waste which reduce its fertility.
Sources of soil pollution are solid
waste ,chemical ,excessive use of
fertilizers and pesticides.
It causes a very bad
effect on environment.

26. Nitrogen Cycle
The nitrogen cycle is the
biogeochemical cycle that describes
the transformations of nitrogen and
nitrogen-containing compounds in
nature. It is a cycle which includes
gaseous components.

27. Carbon Cycle
The carbon cycle is the
biogeochemical cycle by which carbon
is exchanged among the biosphere,
pedosphere, geosphere, hydrosphere,
and atmosphere of the Earth.

28. Global Warming
Gradually increase in the
temperature of Earth
surface and atmosphere too.
Causes very bad effect on all
environment.
It is believed that is caused
by the Green House Effect.

29. Green House Effect
It is a mixture of all harmful
gases that are poisonous.
Ozone didn’t allow to enter
these rays in it.
Cause a very bad effect
for living beings, and also
for all environment.

30. Ozone Layer (O3)
This layer absorbs 93-99% of high
frequency UV rays, which is potentially
damaging to life on earth.
A layer which protects
the environment of
Earth from the ultra
violet rays of Sun.
