describe how a metamorphic rock can become an igneous rock.
A metamorphic rock can become an igneous rock by first melting into magma deep inside the Earth, then cooling and solidifying as new igneous rock.
Quick Scoop
- Metamorphic rocks form when existing rocks are changed by high heat and pressure but do not melt.
- If those same rocks are pushed even deeper, temperatures can get high enough for them to fully melt into magma.
- When that magma cools and crystallizes, it turns into igneous rock, either beneath the surface (intrusive) or after a volcanic eruption (extrusive).
Step‑by‑step journey
- Metamorphic rock is buried deeper by tectonic forces.
- Increasing temperature causes the rock to melt completely, forming molten magma.
- The magma rises or stays underground and begins to cool.
- As it cools, minerals crystallize and solidify into igneous rock like granite or basalt.
Mini story version
Imagine a metamorphic rock like marble slowly sinking deeper into the Earth over millions of years. Eventually it gets so hot that it melts into a pool of glowing magma, which later cools and hardens into a brand‑new igneous rock, completing one loop of the rock cycle.
TL;DR: Metamorphic rock → pushed deeper → melts into magma → magma cools and crystallizes → becomes igneous rock.
