The rock cycle involves 5 main steps: (1) formation of rocks through cooling and solidification of magma/lava, (2) weathering and erosion breaking down rocks into sediments, (3) transportation of these sediments by natural forces, (4) deposition and compaction of sediments to form sedimentary rocks, and (5) metamorphism of existing rocks due to heat and pressure to form metamorphic rocks.
