Answer: Shale changes into Slate.
Explanation:
Shale is a sedimentary rock, formed by the deposition and compression of clay and silt.
Shale layers is buried deep into the earth through the process of deposition (i.e the laying down of rock forming material by natural entities like glaciers, wind, and water).
