Tectonic plates must collide near the igneous rock, driving it under the surface, where it melts into sedimentary rock.
High pressure needs to compact the igneous rock, eventually melting it and forming sedimentary rock as it cools.
When are igneous rocks formed?
when layers of mud form inside Earth
when layers of mud are compressed
when melted rock hardens
when solid rock melts

Metamorphic rock is formed when sedimentary rocks are broken down over time by wind and rain.
Metamorphic rock is formed when lava that erupts from a volcano cools in the atmosphere.
