What rocks can Granite change into?
Granite, or any other rock for that matter, can become metamorphic, sedimentary, or igneous at any time. If the granite is weathered and eroded by wind, water, etc. and the lithified (cemented), it becomes a sedimentary rock. If it melts within the Earth under extreme temperatures and then cools to a solid state, it is an igneous rock. Likewise, if the granite is exposed to extreme temperature and pressure, it can change back into a metamorphic rock. Like I said, these same processes hold true for any rock or mineral in what is known as the Rock Cycle.
