Which kind of rock transforms because of hotness or coldness and pressure and what rock type is formed from the slow cooling of magma under the Earth's surface?
Metamorphic rocks, Meta meaning change and morphos meaning form, are one of the three rock categories in the rock cycle. Metamorphic rock material has been changed by temperature, pressure, and/or fluids. Igneous rocks are also says volcanic rocks. They cool from magma slowly in the crust. If a sedimentary rock is subjected to intense heat it will melt. Once it rises up and cools down, it will form an igneous rock.
