2. Minerals are the naturally occuringsubstance that
has a definite chemical composition.
Minerals can be identified on the basis of
their physical properties like;

21. CONSERVATION OF MINERAL
Minerals are non-renewable resources.
The rate of formation is much smaller than the
rate at which humans consume these minerals

22. POWER RESOURCES
CONVENTIONAL
FIREWOOD
NON-CONVENTIONAL
COAL
PTROLEUM
NATURAL GAS
HYDEL POWER
SOLAR ENERGY
WIND ENERGY
NUCLEAR POWER
GEOTHERMAL ENERGY
TIDAL ENERGY

23. CONVENTIONAL
FIREWOOD
COAL
PTROLEUM
Remains of plants and animals which
were buried under the earth for
millions of years got converted by the
heat and pressure into fossil fuels.
Like:-COAL,PETROLEUM AND
NATURAL GAS.
Electricity from coal is called
THERMAL POWER.
COAL is also referred to as
BURID SUNSHINE.
PETROLEUM is also called as BLACK GOLD.
Leading producers in India are:-DIGBOI in ASSAM.
BOMBAY HIGH in MUMBAI.
PETROLEUM=PETRA(rock)
+ OLEUM (oil)

24. CONVENTIONAL
HYDEL POWER
Rain water or river water stored in dams is made to fall from
heights. The falling water flows through pipes inside the dam
over turbine blades placed at the bottom of the dam.
The moving blades then turn the generator to produce
electricity. This is called HYDRO ELECTRICITY.

25. CONVENTIONAL
HYDEL POWER

26. NON-CONVENTIONAL
SOLAR ENERGY

27. NON-CONVENTIONAL WIND ENERGY

28. NON-CONVENTIONAL NUCLEAR POWER

29. NON-CONVENTIONAL GEOTHERMAL ENERGY

30. NON-CONVENTIONAL
TIDAL ENERGY

31. NON-CONVENTIONAL TIDAL ENERGY

32. NON-CONVENTIONAL
