This is the first and second steps in the formation of sedimentary rock.
What are erosion and deposition?
100
This is how metamorphic rock is formed.
What is changing other rocks through heat, pressure, or chemical reactions.
100
These are the three types of rocks in the rock cycle.
What is igneous, sedimentary, and metamorphic?
100
This is the most abundant rock in the Earth's crust.
What is granite?
200
This is the type of ignous rock that forms above the Earth's surface.
What is extrusive igneous rock?
200
This is the third and fourth steps in sedimentary rock formation.
What are compaction and cementation?
200
This is what foliated means.
What is layered metamorphic rock?
200
This is what happens to a rock that is turning into a sedimentary rock.
What is erosion, deposition, compaction, and cementation?
200
This is the rock made up of quartz, mica, feldspar, and hornblende.
What is granite?
300
This is igneous rock that forms beneath the Earth's surface.
What is intrusive igneous rock?
300
These are the three forms of sedimentary rock.
What are clastic, organic, and chemical?
300
These are the two ways scientist classify metamorphic rock.
What is the arrangement of the grains (foliated and nonfoliated) and the mineral composition?
300
After igneous, this is the next step in the rock cycle.
What is either: ignous, sedimentary, or metamorphic, it depends on the forces acting on the original igneous rock?
300
This is a sedimentary rock formed from gravel with rounded edges.
What is conglomerate?
400
These are the types of grains formed in extrusive igneous rock.
What is very small, can be not visible to the unaided eye?
400
This is the definition of clastic.
What is sedimentary rock that forms from broken bits of other rocks that are compacted?
400
This is where metamorphic rock forms.
What is deep below the surface of the Earth?
400
This is how long the rock cycle lasts.
What is forever?
400
This sedimentary rock that is made up of gravel with sharp edges and cemented together, and the way you spell it.
What is breccia?
500
The translation for the word igneous means this.
What is "born of fire"?
500
This is when dissolved minerals crystalize and glue pieces of sediments together to form a sedimentary rock.
What is cementation?
500
These are two ways that an igneous rock can become a metamorphic rock.
What is turning straight to a metamorphic rock through heat and pressure (granite turning to gneiss) and having the ignous rock broken down by erosion into a sedimentary rock, then changed through heat and pressure to form a metamorphic rock?
500
These are three ways in which breccia could change into a new rock.
What is either melting into magma and reforming as an igneous rock, breaking apart and forming sedimentary rock, or changing through heat and pressure to form a metamorphic rock?
500
This is an extrusive igneous rock that cools and hardens almost immediately with the gas still in it, and this is what the density is like.
What is scoria or pumice that is less dense than other types of rocks?
