There are three types of rocks. Igneous, metaphoric and sedimentary rocks, I am going to go through all three of these rocks and tell you a bit of information about them.
Igneous – These rock are made by mantle cooling. The earth is made of igneous rocks, basalt and carbonite are two examples of igneous rocks.
Metaphoric- this is when a rock is changed by applying either heat of pressure of both. Marble and slate are two examples of a metaphoric rock.
Sedimentary – this is when layers of material build up over thousands of years and become rock. Sandstone and limestone are two example of this.

For thousands of years, people have depended on stone. During the Stone Age, most people depended on stone completely for hear, shelter and hunting animals. The main stone they used was flint. With flint they could start a fire easily and make very sharp arrow or spear heads for hunting. Flint is usually dark grey, black, and green, white, or brown in colour and usually quite small when found.
Flint is a hard form of form of the mineral quartz. It was used as spears and arrows because it could be sharpened easily by cutting thin slivers off it and because it is a very hard stone. Flint has been used as a building material for thousands of years also, it was used to build the Burgh Castle in Norfolk and it is still used to the present day. Flint is common in most areas in Ireland.
