Gold, diamond, rock salt and the graphite used to make the "lead" in pencils are examples of minerals. Each of these minerals is different yet many times minerals look like one another or something else. A piece of green coloured plastic may look identical to an emerald. A very clear piece of quartz may look like a rough diamond.

Types of Rocks | Geology Page

 · There are two basic types: Intrusive igneous rocks crystallize below Earth''s surface, and the slow cooling that occurs there allows large crystals to form. Examples of intrusive igneous rocks are diorite, gabbro, granite, pegmatite, and peridotite. Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals.

Rocks

A Rock, by a simple definition, is a solid with more than one component of a mineral or mineraloid.A single crystal is not a rock; but two crystals that are joined together, even if they are the same mineral, are technically a rock. The minerals or mineraloids may be large enough to be easily identified (such as in a pegmatitic granite), barely distinctive grains (as in a schist), or in a ...
