What is gravel?
This is the name of the starting rock before heat and pressure are applied.
What is parent rock?
This is the set of processes that show how one type of rock can change into another type of rock.
What is the rock cycle?
This test looks at the color of a mineral’s powder, which is the “true” color of a mineral.

What are extrusive rocks?
Weathering and erosion, deposition, and compaction and cementation make this type of sedimentary rock.
What is clastic?
If a metamorphic rock gets hot enough to melt, it becomes this type of rock.
