Metamorphic Rocks - Marble.
Marble is formed from limestone. At high
temperatures and pressures,
the shells
which formed limestone break
down and recrystallise.
The resultant rock is called
marble,
which is much harder than limestone, with a smooth
even texture.
Marble is a valuable
rock for construction and
decoration.
It can be polished to produce an
attractive mottled surface.
Marble is still calcium carbonate,
and reacts
chemically in the same way
as limestone.
