Metamorphicscience 2
a. Foliated – mineral crystals are
arranged in parallel layers or bands (ex. Schist, slate, and gneiss)
b. Nonfoliated – rocks are not banded and do not break into layers (ex. Marble and quartizite)
3. Types of Metamorphic Rocks

Let’s see what Sedimentary stuff we
came up with!

Table of Contents
1. What processes create sedimentary
rock?a. Weatheringb. Erosionc. Depositiond. Compactione. Cementation
*LITHIFICATION=process to make sedimentary
rocks*
a. Weathering – the breakdown of material at the Earth’s surface.g
i. The weathered material is
calledSEDIMENT.
ii. Sediment size varies – mud, sand,
gravel
b. Erosion – movement of sediment from on place to another by WIND, WATER, or ICE.
c. Deposition – dropping off the sediment in a new location.
Now it’s time to put them together!
d. Compaction (Squeezing)
e. Cementation (Gluing)
2. These are all called
CLASTIC SEDIMENTARY
ROCK.
i. Sand becomes sandstone
ii. Clay and mud become shale
iii. Gravel becomes conglomerate
3. Organic sedimentary rock is formed from previously living things.
a. Limestone – ocean life
b. Coal – plant life on land
4. Chemical sedimentary rock is formed from water evaporating and
leaving rocks behind.
Mineral crystals left behind in Death Valley after the water evaporates
Playa Lake in California – in the process of evaporating and leaving chemical rock behind
5. How they’re used:a. Buildingsb. Making cementc. Burning for fuel
