1) Sedimentary rock
2) Sediments
3) Metamorphic rock
4) Igneous rock
6) Weathering and erosion must happen for igneous rock to turn into sediments.
7) Sedimentary rocks can turn into igneous rocks through melting followed by solidification.
8) The three main types of rocks are igneous rock, sedimentary rock, and metamorphic rock.
9) Sedimentary rocks turn into metamorphic rocks through heat and/or pressure (metamorphism).
10) Sediments turn into sedimentary rocks through compaction and/or cementation.
