This animation shows a diagram of the rock cycle and allows the student to see all the possible changes which can occur to that rock type and the process required.   For example, an igneous rock can transform into sediment, metamorphic rock or magma through erosion, heat and pressure or melting.   This gives a complete picture of rock cycle.
