What Does Rock Cycle Mean?
The rock cycle is a geological process that is undergone by the three main rock types: igneous, metamorphic and sedimentary. This process involves transitions between the three types of rock through erosion into sediment and cementing, or heating and pressure. Igneous rock can become sedimentary rock. Sedimentary rock can become metamorphic rock. Metamorphic can become igneous. All rocks are made from minerals.
