The Rock Cycle
The rock cycle is a cycle showing how different types of rocks transform and what type of rock do they transform into. For example if an igneous rock is in enough pressure and heat it can transform into a metamorphic rock, and then if a metamorphic rock is effected by weathering it will transform into sediments, which can transform into a sedimentary rock if it is compact enough. The cycle will then go on and on. But most of these transformations would take a long time usually thousands of years. Therefore a single rock could change into many different forms in a million years.
