Pink = K-feldspars
White = Quartz crystals
Black = hornblende
composed mostly of natural glass
Obsidian
Dominantly made up of decomposed organic matter
Coal
Mineraloid
Opal
True or False
It is easy to identify the composition of rocks if the crystals are visible
True
True or False
Minerals in rocks do not always occur as well-formed crystals
True
- Varying factors during rock formation affect the growth of the mineral constituents
What factors during rock formation affect the growth of the mineral constituents
temperature and pressure
Formed by solidification or magma or lava and/or solidification of volcanic eruption products
Igneous Rocks
Formed by lithification of sediments and/or through chemical and biochemical processes
Sedimentary Rocks
Formed by addition of heat, pressure, and/or chemically active fluids to a pre-existing rock
Metamorphic Rocks
True or False
Igneous rocks can transform into a metamorphic rock simply by exerting large amount of pressure.
True
