What is the Rock Cycle?
The process a rock goes through starts as sediment and becomes a sedimentary rock. Then, it turns into an igneous rock. Finally, it becomes a metamorphic rock.
The process a rock goes through is a result of physical weathering to become a different rock.
The process a rock may go through that will change it into another type of rock.
What does igneous rock become if heat is added and it melts?
A new substance
Sedimentary rock
Sediment
Metamorphic rock
Magma or lava
What is sediment?
Smaller rock
A type of rock
Dust particles
What is left after magma or lava cools
The appearance of rock depends on its
Mineralogy and texture
Predominant mineral
Environment of formation
Degree of weathering
The rock cycle can be most accurately described by which order of events?
Plutonism, uplift, weathering and erosion, burial and lithification, metamorphism
Metamorphism, weathering and erosion, plutonism, uplift
Uplift, metamorphism, burial and lithification, plutonism
Weathering and erosion, plutonism, metamorphism, uplift
Uplift is most likely to occur in which of the following plate-tectonic settings?
The divergent boundary at a mid-ocean ridge
The subsidence of an oceanic plate
Hot spot or mantle plume in the interior of a continent
The convergent boundary where continents collide
Where is the oldest rock in the Grand Canyon?
At the top
In the middle
At the bottom
At the end
To what type of rock does the term ultramafic apply?
The type that contains high concentrations of feldspar
The type that contains the least silica
The type that is high in phosphorus
The type that is low in magnesium
Which descriptive word applies to an igneous rock that is high in feldspar and quartz?
Felsic
Mafic
Plutonic
Cherty
What type of crystals can be seen if a given sample of igneous rock has cooled very quickly?
Very large
Very small
Few in number
of varying sizes
The first minerals to crystallize from a mafic magma are
amphibole and pyroxene
Na-plagioclase and biotite
quartz and muscovite
Ca-plagioclase and olivine
An igneous rock with clearly visible mineral grains has a ---------texture.
aphanitic
phaneritic
glassy
porphyritic
An example of a relatively thin, discordant pluton would be a
sill
dike
laccolith
stock
A sedimentary rock that is made of fragments of rocks cemented together by a mineral is called
chemical
organic
clastic
