The rock becomes too hot that it must turn into liquid form (lava). This would usually mean that the rock had to have come into contact with lava first.
The contact metamorphism process occurs when magma intrudes into surrounding rock, causing the adjacent rock to be heated and recrystallize into a metamorphic rock. The heat and pressure from the magma alter the mineral composition and texture of the surrounding rock, resulting in the creation of a metamorphic rock zone around the magma.
A metamorphic rock is formed by the elements, minor heat, and compression. When the metamorphic rock is melted by magma, this would indicate that the metamorphic rock is under the surface of the earth. If it rises and cools again you will have an extrusive igneous rock. In a lot of cases, this is metamorphic rock on the surface under the influence of lava. This would change the composition and it would not longer be metamorphic, but rather igneous.
To form metamorphic rock from magma, first magma must intrude into existing rock layers. The heat and pressure generated by the magma will cause the surrounding rocks to recrystallize and change mineral composition, transforming into metamorphic rock. This process occurs deep within the Earth's crust and can take millions of years.
When metamorphic rock is deposited deep down in the earth, due to pressure and heat, it could be turned easily to lava. When this lava gets heated up the more, due to convection of heat it is force to come out. It cools off on the earth surface as igneous rock.
Metamorphic rock transforms back into magma through a process called melting, which occurs when temperatures and pressures increase significantly, often due to tectonic activity or proximity to magma sources. When metamorphic rocks are subjected to these extreme conditions, their minerals can break down and re-melt into molten rock. This molten rock can then rise to form magma, which may eventually cool and solidify into igneous rock, completing the rock cycle.
no it can't
if it erodes then sedementry. if it melts in magma then its igneous.
Sedimentary rocks get turned in to metamorphic rocks by heat and pressure. They get heated by magma and convection currents, which causes the rock to change.
magma
If the metamorphic rock becomes hot enough it can melt.
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.
The melting of metamorphic or igneous rock forms magma.
The metamorphic rock melts into magma then cools into igneous rock

i don't not
magma
