Types of ROCK (pg. 182)
6.10 B: Classify rocks as metamorphic, igneous, or sedimentary by the processes
of their formation
Cementation
The changing of sediment into rock by filling
spaces around the sediments with minerals
Lithification
To become rock by compacting sediment under
pressure and filling space by cementation.
Recrystallization
the formation of new mineral grains that are larger
than the original grains
Foliated rock
A “striped” rock. Created by uneven pressure that
deforms the rock
A rock without “stripes” created by equal pressure
Non-foliated rock on each side which causes the minerals to
recrystallize
The squeezing together of layers of sediment due
to the immense weight of the many layers of rock
Compaction
and sediment
The process of breaking down material into smaller
Weathering
pieces
The process of moving sediment or weathered rock
Erosion
from one place to another
Laying down sediment that came from another
location.
Deposition
Sedimentation
Crystal
Rocks
Minerals
Magma
Lava
The process of creating sediment
A single grain of a mineral
Comprised of one or more minerals
Solid containing one or more elements arranged in a
crystalline structure. They compose rocks.
Molten rock beneath the earth’s surface
Molten rock once it is ejected from a volcano
