Rocks Review Game
A naturally occurring, solid mixture
of one or ore minerals and organic
matter
Rocks
How did humans use rocks in the
past?
Tools, weapons, and building
materials
What is the process in which water,
wind, and heat break down rock?
Weathering/erosion
If magma cools quickly, what kind of
texture will the rock have?
Fine-grained
What are 3 ways that magma
forms?
Increase temperature
decrease pressure
change composition
What has to increase for
metamorphism to occur?
Heat and pressure
The process of forming a
sedimentary rock when minerals
dissolve then bond the sediments
together (like glue)
cementation
Layers of sedimentary rock are
called
strata
What are the 3 types of
sedimentary rock
Clastic, chemical, and organic
What type of rock forms when
magma cools?
igneous
What determines the size of the
crystals in an igneous rock?
How fast or slow the
magma/lava cools
Type of igneous rock that forms
when magma cools below the
Earth’s surface
intrusive
Metamorphic rock in which the
mineral grains are arranged in
planes or bands
foliated
What are the two ways rocks are
classified?
Texture and Composition
What does Composition mean?
What a rock is made up of
Light – colored igneous rocks are
called
felsic
Felsic igneous rocks are made up
of mostly
quartz
Dark-colored igneous rocks are
called
mafic
Mafic igneous rocks are made up
of mostly
Plant materials
Process in which sediment is
dropped and comes to rest
deposition
Process by which new rock is
made from old rock
Rock Cycle
The quality of a rock based on the
size and shape of the mineral grains
texture
Minerals used to estimate the
temperature and depth that a rock
undergoes metamorphism
Index minerals
Metamorphic rock in which mineral
grains are NOT arranged in bands
nonfoliated
Process in which layers in
sedimentary rock are formed
stratification
Metamorphic rock formed in large
areas deep under the Earth’s surface
Regional metamorphism
Metamorphic rock formed in
small areas due to rising magma
Contact metamorphism
Igneous rock that cools below
the Earth’s surface
intrusive
