Florian discovers a rock that is broken into pieces. Each piece has several bands. Which type of rock does Florian predict these pieces will change into when subjected to heat and pressure?

Answer: (C)

Explanation: Metamorphic rocks. Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form".

The correct answer is: metamorphic.

Metamorphic rocks are rocks formed from transformation of existing rocks by the influence of pressure, heat or chemically active fluids. Those rocks go through chemical or physical changes-change in form.

The original rock is called protolith and it may be a sedimentary, igneous, or existing metamorphic rock.

Some of the metamorphic minerals are isillimanite, kyanite, andalusite, and some garnet.
