By a process of melting and re-solidification of the melt produced..
Yes.
An igneous rock can change into a metamorphic rock with heat or pressure.
Any rock, be it igneous, sedimentary or metamorphic, can be changed into a metamorphic rock through increased pressure and/or temperature.
All rock types, igneous, sedimentary, and even metamorphic can be altered to new metamorphic rock.
All rock types, igneous, sedimentary, and even metamorphic can be altered to new metamorphic rock.
Metamorphic rock can become igneous rock through high temperature melting of its mineral constituents, followed by cooling and solidification.
Melting and Recrystallization.
Igneous rock can weather and become sedimentary rock . Metamorphic rock can be melted in a volcano and become igneous rock. Igneous rock and sedimentary rock can be heated and pressurized to form metamorphic rock.
I think you mean igneous rock, not ingenious. Answer is none. Igneous rock can change to metamorphic rock.
Yes. It's all part of the rock cycle.
an igneous or sedimentary rock that is changed by heat or pressure
An igneous rock can be metamorphosed (changed) into a metamorphic rock but will no longer be an igneous rock. An igneous body can be intruded into metamorphic rocks but will still be an igneous rock that is different from the surrounding metamorphic rocks. Ethier answer work depending on how the question is read.
