Sandstone experiences intense heat and pressure.

Explanation: Metamorphic rocks form when existing rocks are subjected to high temperature and/or pressure (often deep underground or during mountain-building). Erosion reshapes rocks at the surface, layering/compaction make sedimentary rock but do not create metamorphic rock.
