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
