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
