  1. IGNEOUS PROCESSES 3 https://en.wikipedia.org/wiki/Igneous_rock

  2. What is crystallization? • Formation of crystals • A rock formed by solidification http://glyphwork.com/tag/crystal-magic/

  3. 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

  4. 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

  5. Kinetic Molecular Theory • Solidification-phase change from liquid to solid • Intermolecular forces are forces of attraction between neighboring particles • Supercooled liquid

  6. Intrusive rocks • Solidify beneath the surface • Crystallize from magma • “Phaneritic rock” https://en.wikipedia.org/wiki/Felsic

  7. 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/

  8. Extrusive rocks • Solidify above the surface • Crytallize from lava • “Aphanitic rock” http://www.fellerstone.com/rough-rock/

  9. Basalt Rhyolite http://meteorites.wustl.edu/id/lavarocks.htm https://www.studyblue.com/notes/note/n/igneous-rocks-full-info/deck/14044753 Andesite Obsidian http://pixgood.com/obsidian-rock.html http://imgarcade.com/1/porphyritic-rocks/

  11. Quiz 1-2. Explain this. 3-4. Differentiate melting from crystallization.

  12. 5-7. • What are intrusive igneous rocks? Where does it crystallize? • What are extrusive igneous rocks? Where does it crystallize? 8-10. Explain solidification.
