Rocks are not minerals. They are composed on one or more minerals. For example granite is composed primarily of the minerals quartz, potassium feldspar, and albite. There are some rocks, however, that are composed of substances that aren't minerals. Examples include coal, which is mostly organic, and glassy rocks such as obsidian, pumice, and some varieties of tuff.
Not all rocks are made of minerals. Rocks can be composed of minerals or can be made up of organic materials like shells, fossils, or volcanic glass. Some rocks, like coal or obsidian, do not contain minerals but are still considered rocks.
Rocks contain minerals in them and minerals are just the minerals themselves.
Yes. Rocks are defined as combinations of minerals. The only exception to this would be some volcanic rocks that are composed mostly of glass.
