1. Rocks Study Guide!!!

2. THE ROCK CYCLE Igneous Rocks Sedimentary Rocks Metamorphic Rocks
1st is Magma/lava
Through weathering a rock is
Broken into Sediments/pieces
Foliated
Nonfoliated
INtrusive
EXtrusive
Foliated appears To have bands
No appearance
of bands
Coarse-Grained
Cools slowly
Formed inside
Earth.
Formed by magma
Fine-grained
Cools fast/rapid
Formed outside
Earth.
Formed by lava
Clastic
Chemical
Organic
cemented/glued
Together from rock fragments
Crystallized out of a solution To become a rock
Formed from remains
Of plants & animals
(ex. Coal)

3. Important vocabulary to know!!!
Strata – layers of rock (think of a cake)
Stratification – process where sedimentary rocks are arranged in layers (like a cake)
Rock A naturally occurring solid mixture of one or more minerals or organic matter
How does sedimentary rock form???
1st Weathering – rock is broken into small pieces by (wind, rain, ice,…)
2nd Erosion – Water or wind carries the pieces away
3rd Deposition – pieces are deposited somewhere else (dropped off)
4th Compaction – years go by & the pieces are packed on topped of each
other/weighted
5th Cementation – minerals slowly dissolve, seep into spaces and act like glue/cement, glue the pieces together to make a bigger rock.
6th Sediment – rock and mineral fragments/pieces
