1. The Rock Cycle

2. So…what is the difference between a rock and a mineral?
A mineral is a naturally formed solid material with a crystal structure.
Quartz
Biotite mica
Feldspar

3. So…what is the difference between a rock and a mineral?
A rock is a solid mixture of crystals of one or more minerals.
Granite:
Quartz + Feldspar + Biotite mica

4. Form when lava or magma cools and hardens to form mineral crystals.
The Three Types of Rock
Igneous
Obsidian
Pumice
Granite
Form when lava or magma cools and hardens to form mineral crystals.

5. The Three Types of Rock Sedimentary
Sandstone
Shale
Conglomerate
Form when grains of rock (sediments) collect and harden into new rocks.

6. Form when rocks change as they are heated or squeezed.
The Three Types of Rock
Metamorphic
Gneiss
Quartzite
Schist
Form when rocks change as they are heated or squeezed.

8. Rock Cycle Song (Sing to the tune of "Row, Row, Row Your Boat")
SEDIMENTARY rock Has been formed in layers Often found near water sources With fossils from decayers
Then there's IGNEOUS rock Here since Earth was born Molten Lava, cooled and hardened That's how it is formed
These two types of rocks Can also be transformed With pressure, heat and chemicals METAMORPHIC they'll become.
