WebThe final stage of the metamorphic cycle is the exhumation stage, during which the metamorphic rock is uplifted and exposed to the Earth's surface due to geological processes such as erosion, faulting, or tectonic uplift. This stage can also vary greatly in length, depending on the specific geological processes involved. WebJul 15, 2024 · Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there.
