Sedimentary rocks
sediment settles out of the water
Deposition
small pieces of material that come from rocks or living things

Mineral Composition
process of sediment pressing together to form thick layers
compaction
round hollow rock often lined with mineral crystals
Geode
particle patterns that repeat to create a crystal
crystal structure
rough, jagged edges and uneven surfaces
Fracture
