Question

The history of a certain rock began as a solidified melt, which was then was broken apart by wind, water, and ice. The broken pieces came to rest in a low basin near a coastline and then were buried. There these pieces became heated and squeezed such that the minerals in these pieces altered into other minerals. What type of rock is this?

Answer 1

The answer is metamorphic rock.

Based on the explanation it explains the different changes and transformations that it has undergone. The solidified rock formed from melted rocks is in a state of being an igneous rock. The weathering of this rock going to a low basin and coastline can mean that it is possible that it turned into a sedimentary rock based on its situation. Finally, the heat and pressure in the coastline made sedimentary rocks turn into another type of rock which is the metamorphic rock.
