To know what is involved with quarrying for limestone, and the
advantages and disadvantages of this process

Limestone industry advantages and disadvantages…
Advantages
Disadvantages
Limestone is a valuable natural resource,
used to make things such as glass and
concrete
Limestone quarries are visible from long
distances and may permanently disfigure
the local environment
Limestone quarrying provides
employment opportunities that support
the local economy in towns around the
quarry
Quarrying is a heavy industry that creates
noise and heavy traffic, which damages
people's quality of life

How are the following products formed:  Calcium oxide (CaO), otherwise known as quicklime
 Calcium hydroxide (Ca(OH)2), otherwise known as slaked lime

What does thermal decomposition require?

How are the following products formed:  Calcium oxide (CaO), otherwise known as quicklime – heat is required
(CO2 is also produced)
 Calcium hydroxide (Ca(OH)2), otherwise known as slaked lime – water
is added (a great deal of heat can be released with this reaction)

What does thermal decomposition require – thermal decomposition
requires heat!

You task is to split into groups of 7 people for a quarrying debate – elect one
individual in the group to be the chair person

All of members need to represent one of the following groups: Limeco
representative (the quarrying firm); industrial users of limestone; trade
union representatives ; the National Park authority; local residents; and the
local Conservative group

Read the briefing sheet – it does not matter if you agree or disagree with
the opinions of the group you have been assigned to, what is important is
that you can identify key areas to argue your case for, and get your
message across clearly!

It is up to the chair person to keep order, and be aware of the time
constraints
