What is pink quartz?
This is molten rock found above the earth's surface.
What is lava?
The final 2 processes that turn sediments into sedimentary rocks.
What are compaction and cementation?
Why are the layers of a metamorphic rock wavy, while sedimentary rock has straight, flat layers?
Metamorphic rocks have wavy, not straight layers due to heat and pressure

sediments
When a rock breaks down and the pieces are then dropped elsewhere.
What is deposition?
What shows us how different rocks change types.
Igneous rocks are categorized as _________ or _________, depending on where the molten rock cooled.
