The rock cycle describes how rocks endlessly transform from one type to another through interrelated processes. Igneous rocks form from melting and crystallization of molten material; sedimentary rocks form when sediments are deposited, lithified, and compacted; metamorphic rocks arise when existing rocks are altered by heat and pressure. Weathering and erosion break down rocks and transport materials, which can then become sediments for lithification, continuing the cycle. This interconnected set of transformations among all rock types is why the statement that lists melting, crystallization, weathering, erosion, lithification, and metamorphism as part of transforming between igneous, sedimentary, and metamorphic rocks best describes the rock cycle. The other ideas describe only single pieces of the process, not how rocks continually change type through multiple pathways.
