That would all depend on what type of rock.
it will melt
melt.
There are three ways to melt rock to form lavas. You can use decompression, add volatiles, or conduction. All you need to do is use these strategies to get the rock to its melting point.
If the metamorphic rock becomes hot enough it can melt.
One reason a very hot rock might not melt is if it is composed of minerals with high melting points, such as quartz or feldspar. These minerals can withstand high temperatures before reaching their melting point, allowing the rock to remain solid even at extreme heat.
Volcanoes erupt hot ash or molten rock. It is the heat from this that can melt ice.
Truely.
bc it has too also be pressurized
it can melt and be molten because fire is too hot.
If a rock gets hot enough, it can undergo physical and chemical changes. Depending on the temperature, rocks can melt, undergo metamorphism, or break down into different minerals. Ultimately, it will depend on the type of rock and the intensity of the heat.
When the fluids enter the already hot mantle rock, the melting temperature of the hot rock decreases. As a result, the rock begins to melt.
Igneous rocks-after having the chance to cool down after a melt (metamorphic rocks need pressure as well)
