Types of Minerals
A mineral is a naturally formed, inorganic solid that has a definite crystalline structure. There are 5 ways to identify minerals: color, luster, streak, fracture or cleavage, and hardness. People think that all minerals look like gems, however some actually look like rocks, but rocks and minerals aren't the same. Rocks are made of minerals, but minerals are not made of rocks. (Holt Science and Technology, page 66)
For example, quartz, feldspar, and biotite are all minerals. Combined together these individual minerals all form a rock named granite. (answers.encyclopedia.com)
There are two types of minerals: silicate and nonsilicate minerals. Silicate minerals contain a combination of silicon and oxygen, and nonsilicate minerals are minerals that do not contain a combination of silicon and oxygen. (Holt Science and Technology, page 68)

Types of Rocks
Rocks are naturally occurring solid mixture of one or more minerals and organic matter. (Holt Science and Technology, page 90)
There are three types of rocks: igneous, metamorphic, and sedimentary rocks. Igneous rocks are formed from the solidification of molten rock material. Some examples of igneous rocks are granite, obsidian, basalt, and pumice. Metamorphic rocks have been modified by heat, pressure and chemical process usually while buried deep below Earth's surface. Examples of metamorphic rock are gneiss, marble, schist, and slate. Sedimentary rocks are formed by the accumulation of sediments. Examples of sedimentary rocks are conglomerate, flint, limestone, and sandstone. (www.geology.com)
