Define a Igneous Rock
Intrusive cool slowly large crystals cools quickly small crystals
What are the Types of Rocks?
Igneous
Extrusive
Sedimentary
Define sedimentary rock
- Clastic
- chemical
- minerals crystallize directly from water biochemical forms from remains of once living organisms
Define a metamorphic rock
foliated
has layers
non-foliated
does not have layers
Define rock cycle
processes undergone by rocks in the earth’s crust
(igneous intrusion, uplift, erosion, transportation, deposition as sedimentary rock, metamorphism, remelting, and further igneous intrusion.)
Define compaction
the process by which a sediment progressively loses its porosity due to the effects of loading. This forms part of the process of lithification.
Define Cementation
the binding together of particles or other things by cement.
