Specific Mineral
Glass, a typically transparent material, is made mostly of this mineral.
What is quartz?
This type of rock is made from the solidification of molten rock.
What is igneous rock?
This rock exhibits banding.
What is gneiss?
True or False: A metamorphic rock can undergo metamorphism to become a different metamorphic rock.
What is True?
This is the only general type of rock that can contain fossils.
What is sedimentary rock?
This mineral is green, can be found in some igneous rocks, and has a hardness of 6.5.
What is olivine?
This rock will appear to be a major deformation of a pre-existing rock, one deformed by heat and/or pressure.
What is metamorphic?
This rock is made of compacted plant remains & then underwent regional metamorphism.
What is anthracite coal?
True or False: Sediments can indirectly become any general type of rock, if given enough time & through enough processes.
What is True?
This is the primary exception to the rule regarding igneous rock coloring and whether they are considered felsic or mafic.
What is obsidian?
OR What is volcanic glass?
This mineral is composed of Calcium and Fluorine.
What is fluorite?
This rock shows mineral alignment, which we can call foliation (or in extreme examples, banding).
What is metamorphic rock?
This rock is made of relatively large fragments cemented together that must not have undergone much weathering/erosion.
What is breccia?
These are the two kinds of metamorphism.
What are regional & contact?
[Half-credit allowed]
The minerals talc, muscovite mica, quartz, and olivine are similar because they
A) have the same hardness
B) are the same color
C) contain silicon and oxygen
D) break along cleavage planes
What is C?
OR What is "contain silicon and oxygen?"
This mineral exhibits nonmetallic luster AND cubic cleavage.
What is halite?
This type of rock is made from chemical precipitation and/or evaporation.
What is sedimentary rock?
This rock is made from lava, non-crystalline, felsic, and light-colored.
What is pumice?
These two processes always result in sediment formation.
What are weathering & erosion?
[Half-credit allowed]
An internal arrangement of only carbon atoms can lead to one of two very different minerals: graphite & this gemstone.
This mineral is commonly mined as a source of the element lead (Pb).
What is galena?
The size of this rock's interlocked crystals is dependent on how fast the rock cooled into a rock.
What is igneous rock?
This rock is mafic, made from magma, could never be made from lava, and has a composition of 45% plagioclase feldspar, 40% biotite, 10% pyroxene, and 5% amphibole.
What is gabbro?
As the rate of molten rock solidification quickens, this gets smaller.
What is crystal size?
The color of a mineral in its powdered form when rubbed against another surface, which can be a different color than its color at formation, is called this concept.
What is streak?
