उत्तर १
The rocks contain minerals in the form of ores, but minerals do not contain rocks. Sedimentary rocks contain fossil fuels like coal and petroleum, etc.; igneous rocks are rich in minerals like copper, gold, iron, etc.; and metamorphic rocks contain valuable building stones like marble, garnet, feldspar, etc. Rocks have no definite chemical composition, while minerals have a particular chemical composition.
