1.ORIGIN: Where the igneous rock is formed. a.Extrusive is formed from lava on top of Earth’s surface b.Intrusive is formed from magma underneath Earth’s crust What do the prefixes EX- and IN- mean? The 3 Most Important Things about Classifying Igneous Rocks

2. TEXTURE: Size, shape, and pattern of a rock’s grains or crystals a.Large a.Large crystals form from slow coolingLarge b.Small b.Small crystals form from quick coolingSmall c.Porphyritic c.Porphyritic means part of the magma cools slowly and part cools quickly creating both sizes of crystalPorphyritic

Metamorphic Rocks You will have 5 minutes to read pages When you are finished, look at the pictures and read the captions

___________________ __________ and _________ deep beneath Earth’s surface can change any rock into a metamorphic rock HEATPRESSURE

Geologists classify metamorphic rocks by the arrangement of the g gg grains that make the rock: parallel layers parallel layers 1. Foliated metamorphic rocks will have grains that are arranged in parallel layersparallel layers randomly arranged randomly arranged 2. Non-foliated metamorphic rocks will have grains that are randomly arrangedrandomly arranged
