Heat, for sure, and most often a combination of heat and pressure is needed for metamorphic rock creation.
Metamorphic
A metamorphic rock can become a igneous rock by melting and cooling
Metamorphic rock can not become igneous rock, however igneous rock can become metamorphic. This process happens over time as the rocks are shifted, compressed and heated by the Earth.
A pre-existing, igneous, sedimentary and metamorphic rock.
Any type of rock can become metamorphic.
Any metamorphic rock can melt and recrystallize and become an igneous rock.
If the metamorphic rock becomes hot enough it can melt.
Any rock, be it igneous, sedimentary or metamorphic, can be changed into a metamorphic rock through increased pressure and/or temperature.
Metamorphic rocks are formed from sedimentary rocks.
