Georgia HomeroomSG2Rock and Mineral Formation
Obtain, evaluate, and communicate information about the geologic conditions and processes that form different rocks and minerals through the rock cycle.
Appears in: Science, High School
Expectations
SG2.aPlan and carry out investigations to explore how chemical variation and geological processes result in the formation of different rock forming minerals. (Clarification statement: This could include the formation of quartz, K-feldspar, plagioclase, muscovite, biotite, amphibole, pyroxene, olivine, kaolinite, calcite, halite, gypsum, chlorite, garnet and staurolite.)
SG2.bDevelop and use models to demonstrate the processes that form plutonic (intrusive) and volcanic (extrusive) igneous rocks of differing compositions, and textures.
SG2.cAsk questions to differentiate between processes that form various types of sedimentary rocks (i.e., weathering, erosion, deposition, burial, compaction and cementation).
SG2.dConstruct an explanation for how igneous and sedimentary rocks transform to different types of metamorphic rocks. (Clarification statement: Explain how different conditions of metamorphism and starting (parent) rock compositions determine metamorphic rock type.)
