The Rock Cycle
100
A student found a rock in the desert that was mixed with clay, gravel, and sand. What type of rock did the student find?
Sedimentary
100
True or False: Rocks are made up of minerals.
True
100
These substances make up the composition of rocks.
What are minerals?
100
All types of rocks are classified by this
What is their origin / how they form?
100
These processes occur in order to create sediments
What are weathering and erosion?
200
This test is the most useful test when identifying minerals
What is hardness?
200
This test is used by scratching a mineral on another object
What is the Hardness test?
200
This is the most useful way to identify a clastic sedimentary rock
What is grain size?
200
These types of rocks can contain vesicular textures
What are igneous rocks?
200
This process occurs to create igneous rocks
What is the solidification of magma?
300
This test by scratching a mineral on a porcelain plate and examining the powder's color, as shown in the picture.
What is streak?
300
This test is the least reliable when determining a mineral
What is color?
300
Igneous rocks that form within the Earth are classified as this
What is intrusive?
300
What steps would a scientist need, to change a metamorphic rock into igneous rock?
What is melting and cooling of molten material?
300
Cementation and compaction are processes that create this rock
What is a Sedimentary?
400
This test can be used to identify calcite if other tests cannot distinguish it from another mineral
What is an acid test?
400
These substances make up the composition of minerals
What are elements?
400
This sedimentary rock is formed by the cementation of sea shells
What is limestone?
400
This type of rock is the only type that can contain fossils
What is sedimentary?
400
This process occurs to create magma
What is melting?
500
This type of rock typically has mineral alignment or banding.
What is metamorphic rocks?
500
This determines the physical and chemical properties of minerals
What is the internal arrangement of atoms?
500
This igneous rock is composed of only Olivine
What is Dunite?
500
Igneous rocks that are classified as mafic are rich in these two elements
What is Fe (iron) and Mg (Magnesium)?
500
These processes occur after sediments are created but before compaction and cementation
What are deposition and burial?
