Intrusive igneous rocks form when magma cools and solidifies beneath the Earth's surface. Slow cooling allows large crystals to grow (coarse-grained texture) — examples: granite, gabbro, diorite.

(Other choices: magma cooling on the surface makes extrusive igneous rocks; heat and pressure make metamorphic rocks; compaction of sediments makes sedimentary rocks.)
