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.
In order to form magma, what must happen to sedimentary, metamorphic or igneous rocks? For weathering & erosion to occur, what process will the rock usually go through first or at the same time? Can sedimentary rock form directly from metamorphic rock? Explain your answer. All rocks follow the same pathway through the rock cycle is a false statement. Why? How does granite (igneous) change into sandstone (sedimentary)? Define igneous rocks.
