Limestone, sandstone and shale
Sediments were deposited on beds of
Seas lakes and land
Metamorphosis means
To change

Heat and pressure
Metamorphic rocks contain
Slate, marble and Quanzite
Granite is formed in
Maurne mountains and Wicklow mountains
Basalt varies in colours
Black to grey
Basalt is found in
Antrim Derry plateau, most famously in the giants causeway
Limestone remains
Tiny sea creatures, fish and shells

White in colour but when presented it can be in varies of colours red green and black
Marble is formed mainly in

Grains of Quartz tightly packed together
Quanzite varies in colours
Grey to white
Quanzite is found
In mayo dunegal and Wicklow
Igneous rock is formed when
Hot molten magma cools under the earths surface or within the crust
Sedimentary rocks formed when
From the remains Sediments, rocks, animals and plants
Granite is formed when
Molten magma cools under the earths surface
Basalt is formed when
Lava cools under the earths surface
Limestone is formed from
The remains of tiny sea creatures
Marble was formed when
Limestone was out under great heat and pressure to form marble
Quartzite was formed when
Sandstone came into contact with magma deep in the earths crust
