Learn about the formation of igneous rocks through the processes of crystallization, melting, and solidification. Explore the concepts of nucleation, crystal growth, and the different types of rocks that crystallize beneath or above the Earth's surface.

IGNEOUS PROCESSES 3 https://en.wikipedia.org/wiki/Igneous_rock
What is crystallization? • Formation of crystals • A rock formed by solidification http://glyphwork.com/tag/crystal-magic/
How does it happen? • Nucleation • Crystal growth-diffusion of the molecules http://aseptec-sg.com/product_info.php?cPath=76_79_80&products_id=220
Melting-solid to liquid • Crystallization-liquid to solid http://brooklynbrewery.com/blog/event/guided-tasting-whole-foods-uws/ https://diveratocha.wordpress.com/2014/02/13/concurso-de-cristalizacion
Kinetic Molecular Theory • Solidification-phase change from liquid to solid • Intermolecular forces are forces of attraction between neighboring particles • Supercooled liquid
Intrusive rocks • Solidify beneath the surface • Crystallize from magma • “Phaneritic rock” https://en.wikipedia.org/wiki/Felsic
Dunite Diorite http://geology.about.com/od/rocks/ig/igrockindex/rocpicdunite.htm http://www.sandatlas.org/dunite/ Gabbro Granite http://geology.about.com/od/rocks/ig/igrockindex/rocpicgabbro.htm http://www.yecheadquarters.org/granite-rock-proves-creation/
Extrusive rocks • Solidify above the surface • Crytallize from lava • “Aphanitic rock” http://www.fellerstone.com/rough-rock/
