The never‐ending series of natural geological processes that continuously refashions, redistributes, and recycles material from and on the Earth's crust, including weathering, erosion, sediment transport, deposition, and lithification of sedimentary rocks, metamorphism, and all the processes that create igneous rocks. The rock cycle operates in much the same way as the major biogeochemical cycles and the global water cycle, but much more slowly over the full span of geological time. Also known as the geological cycle.
