The rock cycle is a network, not one compulsory circle. Surface weathering breaks rock down; erosion transports it; deposition accumulates sediment; burial, compaction and cementation can form sedimentary rock. Heat and pressure without complete melting can form metamorphic rock. Complete melting followed by cooling and crystallisation produces igneous rock.
Rock properties record formation. Slow underground cooling can produce larger igneous crystals, while rapid surface cooling produces smaller crystals or glassy textures. Layers, grains and fossils can support a sedimentary interpretation; foliation and recrystallisation can support metamorphism.
Properties influence use. Hardness, toughness, grain size, workability and durability affect whether stone suits construction, grinding or cutting. First Nations quarry and tool-stone knowledge should be taught as purposeful material selection grounded in knowledge of Country. Mining and rehabilitation decisions also involve erosion, habitat and water impacts.
