- LIMESTONE AND BUILDING MATERIALS
- Malham cove
- crucial for buildings, cement and concrete
- Social impacts
- In different
parts of the
country there's
more available -
dictates what
building
materials people
used.
- Quarrying
- ADVANTAGES- It is a
valuable natural resource,
makes glass and concrete
- creates employment-
cost is low unlike stone.
- DISADVANTAGES -
creates noise and
visual pollution -
creates traffic, slow
people down - effect
tourism.

- Limestone reacts with
carbon dioxide which
dissovles in rain water to
make acid rain. Due to the
increase in fossil fuels rain is
becoming more acidic.
- Concrete is easily
shaped, which means
you can use it for a
variety of different
jobs eg. building high
rise buildings
- In different
parts of the
country there's
more available -

building
materials people
used.
- Malham cove
- Limestone is mainly calcuim carbonate - CaCO3
- THERMAL DECOMPOSITION
- Depending on where the
metal is on the reactivity
series will dictate how much
energy/heat is use to
decompose it. High - needs
lots of energy. Low - need
less energy
- Calcium carbonate ----heat----> calcium oxide + carbon dioxide
Ca3 ---heat--> CaO +CO2
- Copper carbonate ----heat----> copper oxide + carbon dioxide
CuC03 ---HEAT---> CuO + CO2
- Colour change -
yellow when hot,
white when cold
- Copper carbonate ----heat----> copper oxide + carbon dioxide
CuC03 ---HEAT---> CuO + CO2
- Making calcium Hydroxide
- water reacts to with
calcium oxide, to produce
calcium hydroxide ( which
is an alkali, can be used to
neutralise acids )
- refure to notes
