Different types of rocks have different properties, characteristics and uses.
Some rocks are harder than others. For example, granite is a very hard rock so it is a good material for building as it is very resistant. ( See Picture 1)
Marble is another hard rock. It has an attractive texture and colour and it can be cut and polished so it is used to make floor tiles and wall tiles. Some statues are made from marble too. (See Picture 2)
Chalk is a soft rock and wears away easily. This makes it ideal for making chalk sticks to write on blackboards. (See Picture 3)
Slate also splits easily into thin sheets. This makes it ideal for making roof tiles seen in most houses abroad. (See Picture 4)
Now study the following table which gives more examples of uses of different types of rock.
