In short, the rock cycle is the name for the processes that forms and recycles the different types or rocks on our planet. Rocks begin the cycle as igneous rocks, erode into sedimentary rocks then change into metamorphic rocks, finally the rocks melt back to magma and start the process again.
All rocks are connected in a cycle of creation, change, and destruction called the Rock Cycle. The rock cycle begins with molten rock (magma below ground, lava above ground), which cools and hardens to form igneous rock. Exposure to weathering and erosional forces, break the original rock into smaller pieces.
