If the metamorphic rock becomes hot enough it can melt.
Any metamorphic rock can melt and recrystallize and become an igneous rock.
Metamorphic rock which is exposed to increasing heat and pressure from various sources can eventually melt. If this melt then solidifies, it has become igneous rock.
Yes. A metamorphic rock can melt and the re-solidify as an igneous rock.
Metamorphic rock
Igneous rocks-after having the chance to cool down after a melt (metamorphic rocks need pressure as well)
Metamorphic rock which is exposed to increasing heat and pressure from various sources can eventually melt. If this melt then solidifies, it has become igneous rock.
It must melt.
When minerals in igneous and metamorphic rocks melt, they become magma, which can eventually solidify to form igneous rocks. In sedimentary rocks, when minerals melt, they can alter the rock's texture and composition, leading to the formation of metamorphic rocks through processes like recrystallization and metamorphism.
Yes. A metamorphic rock can be metamorphosed into a higher-grade metamorphic rock. It can be weather into sediment and re-lithified into a sedimentary rock, or it can melt then solidify to become an igneous rock.
yes
If a metamorphic rock were to reach the mantle and melt, it would become magma. If that magma were then to recrystallize it would be an igneous rock.
