Rock cycle changes the rock into another by exposure on surface , weathering and deposition and deep burial again.Below is a simple explanation


First magma when rises and erupts on surface, igneous rock is formed. This igneous rock when exposed to weathering (Physical ,chemical and biological) starts to break down and ultimately turns into sediments which start to deposit on surface. When large number of sediments(particles) accumulate at deposition site, they impart burden on underlying sediments and with time become compact and form sedimentary rock. This sedimentary rock when again buried deep at temperature and pressure conditions considerably turns into Metamorphic rock. This is how it works hope this helps thanks
