Answered by GPT-5 mini AI
Granite is an intrusive (plutonic) igneous rock. It forms from magma that cools slowly deep underground, producing large, visible crystals of quartz, feldspar and mica. The extrusive (volcanic) equivalent of granite is rhyolite, which cools quickly at the surface and is fine‑grained.
