Rock (geology)

In geology, rock or stone is a naturally occurring solid aggregate of one or more minerals or mineraloids. For example, the common rock granite is a combination of the quartz, feldspar and biotite minerals. The Earth's outer solid layer, the lithosphere, is made of rock.

Rocks have been used by mankind throughout history. From the Stone Age, rocks have been used for tools. The minerals and metals found in rocks have been essential to human civilization.

Three major groups of rocks are defined: igneous, sedimentary, and metamorphic. The scientific study of rocks is called petrology, which is an essential component of geology.

Classification

At a granular level, rocks are composed of grains of minerals, which, in turn, are homogeneous solids formed from a chemical compound that is arranged in an orderly manner. The aggregate minerals forming the rock are held together by chemical bonds. The types and abundance of minerals in a rock are determined by the manner in which the rock was formed. Many rocks contain silica (SiO2); a compound of silicon and oxygen that forms 74.3% of the Earth's crust. This material forms crystals with other compounds in the rock. The proportion of silica in rocks and minerals is a major factor in determining their name and properties.

Stone (disambiguation)

A stone is a small piece of rock.

    It's just like you to cause a scene
    It's just like me to tell tales
    I know it weighs heavy
    But it doesn't have to be this way
    Just let the stones from their slings
    You know you can throw sharper things
    Just let the pain fold away
    You'll slip your chains sooner that way
    What comes down to burden you
    Is just like a test that never fails
    And I know it's hard for you
    But you don't see the beauty that I see
    Just let the stone falls from their slings
    You know you can throw sharper things
    Just let the pain fold away
    You'll slip your chains sooner that way
    And I will be the last one down
    For I see more than just a noose
    Allow me to show you what I mean
    Just take my hand it's alright
    I know you're weak from all your fight
    just let the fear of it all
