Metamorphic rocks do not have a specific melting point since they can vary widely in composition and texture. However, generally, they begin to melt at temperatures between 600 to 800 degrees Celsius (1,112 to 1,472 degrees Fahrenheit). The exact temperature can depend on factors like pressure and the specific minerals present in the rock. Under high-pressure conditions, melting can occur at higher temperatures.
Igneous rocks-after having the chance to cool down after a melt (metamorphic rocks need pressure as well)
It must melt.
Yes. There are degrees of rock metamorphism, where a metamorphic rock can be altered into another metamorphic rock by increased pressure and heat.
No, rock does not melt when it is changing into metamorphic rock. Metamorphic rocks form from pre-existing rocks, such as sedimentary or igneous rocks, through a process called metamorphism. This process involves changes in temperature, pressure, or the presence of fluids, which cause the minerals in the rock to recrystallize without melting.
when sedimentary melts the heat squeezes the rock then it becomes a metamorphic rock.
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.

It must melt.
if rock melts it will form magma, which leads to the formation of igneous rocks
it turns into sand
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.
