They form at the surface in environments such as beaches, river, the ocean, place that sand, mud, and other types of sediment collect, when it heated it become metamorphic rocks, the crystals changed in rock when it had been metamorphosed. The rocks pushsd it into lava and it will become igneous rocks, when it rains the igneous rocks turns into sedimentary rocks again. This is the rock cycle.
