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.
Cobalt is a mineral, not a rock.
A mineral is basically a mixture of different substances that consist of rocks (solid form) and some other things. While it is in its other form (liquid) it contains some useful substances such as zinc and etc.

Rocks contain non-mineral matter. Examples of these are water and gases such as hydrogen and radon. Other compounds like hydrocarbons can also be a component of some rocks.
Some extrusive igneous rocks have individual mineral crystals that are too small to be seen without magnification.
No, to make a rock a mineral does not have to be in it.
Most rocks are composed of several minerals. Some rocks, such as limestone, can have only one mineral. Some rocks, such as obsidian, a volcanic glass have no distinguishable minerals. A mineral has a specific range of chemical compositon and a stable crystalline structure. If the substance in question does not have a crystalline structure, then it is a rock.
Must be some kind of mineral deficiency.
A round rock with pretty crystals of some mineral in them is called a, "Geode" (jee-owed)
The most common cause of red color in rocks is iron.
