Rock Cycle Song

(Sing to the tune of "Row, Row, Row Your Boat")

SEDIMENTARY rock Has been formed in layers Often found near water sources

With fossils from decayers Then there's IGNEOUS rock Here since Earth was born Molten Lava, cooled and hardened

That's how it is formed These two types of rocks Can also be transformed With pressure, heat and chemicals
