What things are made out of rocks?
Nearly everything. “Rock” is a pretty loose term. Rocks are made up of minerals and nearly everything has minerals of one form or another. Your computer is made up of several minerals and elements… Silica, copper, titanium, and iron for example. If you are wondering more what things are made of rock itself rather than the minerals that make up the rock, this list is pretty large too. Counter tops can be made of granite, marble or plagioclase. Buildings, walls, streets and bridges may be made of all kinds of different rocks. Everything you see, whether it’s organic or mineral or whatever, probably had some origin from rocks… even the phosphate in your teeth!
