Igneous rocks form from when molten rock (magma under ground or lava on the surface) cools and solidifies. Metamirphic rocks result from other rocks being modified under heat and pressure while still in the solid state.

igneous rocks started as melted lava and cooled to be rocks. Metamorphic rock started as a sedimentary rock, and was heated up and put under pressure to create the metamorphic rock. Classic example - igneous = obsidian. Metamorphic = marble (marble is limestone that's been heated and squeezed a lot).
cycle means it cycles between sedimentary,metamorphic and igneous rocks. cycle means it cycles between sedimentary,metamorphic and igneous rocks. -Mrs.Zalenski
it is an metamorphic rock, because of the pressure it gets hot and it is formed underground.
Igneous rocks are formed when rocks reach the melting point becoming magma, then the magma starts to cool and crystallizes to form igneous rocks. Metamorphic rocks are made when they come in contact with a mass of magma but does not melt providing the energy to drive chemical reactions that recrystallize minerals.

Metamorphic rock becomes igneous rock when it is melted, then solidifies.
No, metamorphic can be formed by either igneous or sedimetary rock.
