Rocks may be speckled or solid-colored, bumpy or smooth, dense or filled with holes. A rock's look has a lot to do with its mineral make-up. But, just as important is how the rock formed. There are three types of rock formations. One type forms when melted rock cools and hardens. A second type consists of layers of small particles.

A rock is an aggregate of one or more minerals or mineraloids. Some rocks, such as limestone or quartzite, are composed primarily of one mineral – calcite or aragonite in the case of limestone, and quartz in the latter case. Other rocks can be defined by relative abundances of key (essential) minerals; a granite is defined by proportions of quartz, alkali feldspar, and
