A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition and the way in which it is formed. Rocks are usually grouped into three main groups: igneous rocks, metamorphic rocks and sedimentary rocks.
Minerals are solid substances that are present in nature and can be made of one element or more elements combined together (chemical compounds). Gold, Silver and carbon are elements that form minerals on their own. ... For example, rock salt or kitchen salt is a mineral formed of cubic-shaped crystals.
