What turns sediments into sedimentary rock
Compacting and cementing
When minerals are deposited between the pieces of sediments
cementation
When sediments come to rest and begin to pile up
Deposition
Granite (igneous) undergoes metamorphism and becomes Gneiss (metamorphic rock) what is the parent rock?
