Rock's can be used for many different reason's. They can be used to build road's, building's, statue's, and for building home's. They are also used in the making of tombstone's.

Rocks are quite useful to our current way of life. Tombstones along with materials for roads can be carved from rocks. Certain cosmetics have been made up of rocks. I'm not sure I would want to use those. You can find more information here: http://library.thinkquest.org/J002289/us...
