- Definition of a mineral
- solid natural inorganic ordered internal structure specific chemical composition
- Composition of the crust
- 46 Oxygen 28 Silicon 8 Aluminum
- Composition of mantle
- oxygen, silicon
- Composition for the core
- iron and nickel
- Calcite: what its uses is and chemical formula is
- cement CaCO3
- Dolomite: chemical formula is
- CaMg(CO3)2
- Halite: what its uses is and chemical formula is
- table salt NaCl
- what are the five ways silicate tetrahedral can be arranged?
- Independent single chain Double chain Sheet Framework
- What are non silicate minerals
- Carbonates, Evaporites, Oxides, Sulfides, Native elements
- What is a rock?
- solid, naturally occuring cohesive
- Define: Aphanitic
- small crystals
- Define: Phaneritic
- large crystals, visibl
- Plutonic vs Volcanic
- Plutonic= intrusive Volcanic=extrusive
- Define: Porphyritic
- both large and small crystals
- Define: Glassy
- consists of glass when magma erupts on the surface and cools really fast
- Define: Vesicular
- volcanic rocks that has small holes formed near the surface
- Mafic vs Felsic
- Mafic= Low Si, High melting temp Felsic=High Si, low melting point
- Granite -Intrusive/extrusive -Felsic/intermediate/mafic/ultra -looks like
- Felsic, intrusive salt and pepper mostly salt
- Diorite -Intrusive/extrusive -Felsic/intermediate/mafic/ultra -looks like-Intrusive/extrusive -Felsic/intermediate/mafic/ultra -looks like
- intermediate, intrusive salt and pepper rock
- Gabbro -Intrusive/extrusive -Felsic/intermediate/mafic/ultra -looks like
- mafic, intrusive mostly pepper
- Perdotite -Intrusive/extrusive -Felsic/intermediate/mafic/ultra -looks like
- ultra mafic, intrusive pretty much pure olivine
- Rhyolite -Intrusive/extrusive -Felsic/intermediate/mafic/ultra -looks like
- Felsic, extrusive
- Andesite -Intrusive/extrusive -Felsic/intermediate/mafic/ultra -looks like
- intermediate, extrusive
- Basalt -Intrusive/extrusive -Felsic/intermediate/mafic/ultra -looks like
- Mafic and extrusive
- how are sedimentary rocks classified
- Breccia Conglomerate Sandstone Silt Mudstone Shale
