All rocks are made of these.
What are minerals?
100
This is a characteristic used to identify sedimentary rocks.
What are sediments or visible fossils?
100
What is one of the characteristics used to identify igneous rocks?
What are visible crystals, vesicles (gas pockets/bubbles), or glassy texture?
100
What characteristics is used to identify metamorphic rocks?
What is foliation?
100
Melting and solidification form what type of rock?
What are igneous rocks?
200
Name a mineral with metallic luster.
What is graphic, galena, magnetite, pyrite, or hematite.
200
This is a rock made out of compacted plant remains.
What is bituminous coal?
200
This a rock with a glassy texture.
What is obsidian, pumice, scoria, or basaltic glass?
200
Hornfels is formed from this type of metamorphism.
What is contact metamorphism?
200
Metamorphic rocks are formed by these two factors.
What are heat and pressure?
300
This is the pattern in which a mineral breaks.
What is cleavage?
300
The rock breccia is made of this kind of fragments.
What are angular fragments?
300
This is an intrusive rock with felsic composition.
What is granite or pegmatite?
300
Name a foliated metamorphic rock made almost entirely of the mineral mica.
What is slate?
300
These are two of the four processes that lead to the formation of a sedimentary rock.
What are compaction, cementation, deposition, or burial?
400
This mineral bubbles with acid and has a hardness of 3.
What is calcite?
400
This is a chemically formed rock made of a mineral that is often used in food.
What is rock salt?
400
Name two minerals found in felsic igneous rocks.
What are quartz, potassium feldspar, plagioclase feldspar, biotite, or amphibole.
400
This is a foliated metamorphic rock with banding and coarse grains.
What is gneiss?
400
Weathering and erosion lead to this step of the rock cycle.
What are sediments?
500
This determines the properties and physical characteristics of different minerals.
What is the internal arrangement of atoms?
500
Sedimentary rocks with shell fossils are usually formed in this type of environment.
What is aquatic or oceanic or water?
500
Name a non-vesicular rock composed mostly of plagioclase feldspar and pyroxene.
What is basalt, diabase, or gabbro.
500
This is a non-foliated metamorphic rock formed from a crystalline, bioclastic sedimentary rock.
What is marble?
500
This stage of the rock cycle is the precursor to all igneous rocks.
What is magma or lava?
