What is the 1st blank?
Igneous
What is the meaning of the name igneous rocks, and how/where was it made?
Meaning-"ignis"- fire
How/where made- From magma or lava on or beneath earth's surface
What is the #1 rock in abundance on Earth?
Basalt
What is the meaning of the name sedimentary rocks, and how/where was it made?
Meaning- from sediment (small solid pieces of material)
How/where made- forms through series of processes: EDCCCC
What is the meaning of the name metamorphic rocks, and how/where was it made?
Meaning- name means "change form"
How/where made- three forces can change any rock: heat, pressure, chemical reactions (silica)

What are the 2nd and 3rd blanks?
extrusive, organic
What is the difference between intrusive and extrusive?
Intrusive- magma hardened below earth's surface (stays inside earth)
Extrusive- lava erupted onto earth's surface (exits to earth's surface)
What is the #2 rock in abundance on Earth?
Granite
What is the definition and sample rock for clastic?(sedimentary type of rock)
Definition- rock fragments squeezed together
Sample rock- shale
What are the three properties that create metamorphic rocks (HPC)?
H- heat
P- pressure
C- chemical name= silica

What are the 4th, 5th, and 6th blanks?
Chemical, Foliated, Metamorphic
What is the #1 intrusive igneous rock?
What is the #1 extrusive igneous rock?
Granite, basalt
What are the characteristics used to classify rocks (CCTO)?
C- composition
C- color
T- texture
O- origin
What are the definitions and sample rocks for organic and chemical?(sedimentary types of rock)
Organic:
Definition- forms from once living material
Sample rock- coal
Chemical:
Definition- forms from minerals dissolved in water solution
Sample rock- halite (rock salt)
What child rock comes from granite?
Gneiss
Granite = parent rock
Metamorphoses into
Gneiss = child rock

Fill out this table to show the cooling effect upon the size of crystals (ROC= rate of cooling):
grains |rock sample name| ROC during formation
coarse grains|1.______|2.__________________
fine grains|3.________|4.___________________
no visible grains|5._______|6._________________
1. porphyry
2. slow cooling inside earth
3. granite
4. more rapid cooling than coarse-grained rock
5. obsidian
6. most rapid cooling rate of all
What rock comprises the continents? What rock comprises the oceanic floor?
Continents: granite
Oceanic floor: basalt
What child rock comes from sandstone? What child rock comes from shale?
Sandstone: quartzite
Sandstone = parent rock
Metamorphoses into
Quartzite = child rock
