Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. ... Igneous rock forms when magma cools and makes crystals. Magma is a hot liquid made of melted minerals
Igneous rocks would be turned into sediments through weathering and erosion and then those sediments would then be compacted and cemented which would then turn those sediments into sedimentary rocks.
Hope that this helped :)
