What is ore?
Ore is a naturally occurring substance from
which minerals can be extracted.
What is mineral?
A naturally occurring, homogeneous
inorganic solid substance having a definite
chemical composition.
Eg. Gold and silver ---- inorganic
Coal and Petroleum ---- organic

7.  Metals are Good Conductors of Heat and Electricity
 Metals have a shiny appearance or luster
 Metals can be easily beaten into a thin sheet (malleable)
 Metals are heavy - dense
 Metals are hard
 Metals only melt when they are extremely hot - heat resistant
 Metals are sonorous (they make a bell-like sound)
 Metals bend rather than break, they are elastic
Properties of Metals

8. 
 Non-metals vary greatly in their appearance.
 They are not lustrous and are generally poor conductors of
heat and electricity.
 The melting points of non-metals are generally lower than
those of metals. However, diamond, an allotropic form of
carbon, has a high melting point of 3570 degree Celsius.
 Non-metals are not malleable and ductile, like the metals.
 Eg. Limestone, Mica, Gypsum, Coal, Petroleum, etc.
Non-metals

9. 
 Ferrous – Minerals contain iron
 Non-ferrous – Minerals do not contain iron
Ferrous and non-ferrous

17. 
The mineral content of the ore/
Concentration of mineral in the ore
The type of formation or
structure/ The ease of extraction
The cost of extraction/ Closeness
to the market

mineral extraction
commercially/economically viable?

Concentration of mineral in the
The ease of extraction
Closeness to the market
Q. Describe any three factors which play a very
important role in turning a mineral reserve into a mine.

24. 
Minerals are non-renewable resources.
It takes 1000s of years of the formation
The rate of formation is much smaller
than the rate at which the humans
consume the minerals.
Why conservation of
minerals is necessary?

25. Conventional sources of energy.
They are exhaustible except water
They cause pollution when used, as they emit
smoke and ash
They are very expensive to be maintained,
stored and transmitted as they are carried over
long distance through transmission grid and
lines.
Egs. Coal, petroleum, natural gas, firewood,
hydel power
Distinguish between conventional and
non-conventional sources of energy.

26. 
Non-conventional sources of energy.
They are inexhaustible
They are generally pollution free
Less expensive due to local use and
easy to maintain
Egs. Solar, wind, tidal, biogas,
geothermal
Distinguish between conventional and
non-conventional sources of energy.

27. 
Aluminium is highly reactive metal
and it reacts with the food processed
in aluminium utensils or wrapped in
aluminium foil.
When we wrap food in aluminium
foil it leach out and make it harmful
for our health.
Aluminium & its side effects

28. 
More the food is heated more will be the
leaching.
It is more reactive to the acidic and
spicier food.
It is easily absorbed by the acidic food.

29. Alzheimer
Memory loss
Anxiety
Kidney failure
Asthma
Abdominal pain
Diseases caused due to a
aluminium.
