Rocks – Igneous – Sedimentary – Metamorphic. and Meteorites

May 4, 2014

Greetings from the Bluff Park Back Porch, way up yonder on Shades Mountain (1,109′) in Alabama:

 




Minerals and Rocks = “The Good Life from the Ground”
“If it ain’t grown, its got to be mined”

ROCKS

Rocks are made up of minerals and cover the earth.

Minerals:    http://en.wikipedia.org/wiki/Mineral
(Needless to say, we or I could make a career by staying with minerals.  “There are over 4,900 known mineral species.”

Rocks:    http://en.wikipedia.org/wiki/Rock_%28geology%29

There are 3 Classifications for Rocks

http://www.rocks-rock.com/rock-types.html

    Igneous:    “(derived from the Latin word igneus meaning of fire, from ignis meaning fire) forms through the cooling and solidification of magma or lava.”
Images of Igneous Rocks:    http://images.search.yahoo.com/search/images;_ylt=A0LEVwm.ZWZTRhsAlg9XNyoA;_ylu=X3oDMTBsa3ZzMnBvBHNlYwNzYwRjb2xvA2JmMQR2dGlkAw–?_adv_prop=image&fr=moz35&sz=all&va=igneous+rocks

    Sedimentary:    are formed at the earth’s surface by the accumulation and cementation of fragments of earlier rocks, minerals, and organisms or as chemical precipitates and organic growths in water (sedimentation).”

    Metamorphic:    “are formed by subjecting any rock type—sedimentary rock, igneous rock or another older metamorphic rock—to different temperature and pressure conditions than those in which the original rock was formed. This process is called metamorphism; meaning to “change in form”.”

?    I have include a fourth classification, Meteorites:    “is a solid piece of debris, from such sources as asteroids or comets, that originates in outer space and survives its impact with the Earth’s surface.”
