How do metamorphic rocks change into magma?

Question

Leo Arens · Accepted Answer

Metamorphic rock is rock changed under pressure and heat (though not tremendous).
Magma is rock liquified under tremendous heat and pressure.

Rock that has undergone slight changes due to heat and pressure is known as metamorphic rock. Applying pressure to an object that has gaps or spaces can cause those spaces to close. Additionally, applying pressure can cause heat and close contact between atoms, which can speed up chemical reactions. Rock liquefies when the pressure and temperature are too high, resulting in magma. Lava is simply brought to the surface by magma; if it does not cool down quickly enough during its ascent, it will appear on the surface as flowing liquid rock, as it does in Hawaii.

undefined Metamorphic rocks can change into magma through the process of partial melting. When metamorphic rocks are subjected to high temperatures and pressure beneath the Earth's surface, certain minerals within the rocks may start to melt while others remain solid. This partial melting can result in the formation of magma, which is molten rock beneath the Earth's surface. The magma may then migrate upwards through the Earth's crust and eventually reach the surface through volcanic activity, where it can solidify into igneous rocks.
