Igneous rock is formed from the cooling and solidification of molten rock material, known as magma or lava. When lava cools quickly, typically upon coming into contact with water or air, it forms igneous rocks that usually have a fine-grained texture, as the rapid cooling does not allow large crystals to form. This process can occur during volcanic eruptions, where lava flows and rapidly cools upon reaching the surface.

Granite, while also an igneous rock, is formed from the slow cooling of magma beneath the Earth’s surface, leading to a coarse-grained texture, which is distinct from the rapid cooling process described in the question. Metamorphic rock, on the other hand, is created from the alteration of existing rocks due to heat and pressure, and sedimentary rock is formed from the accumulation and lithification of mineral and organic particles over time, neither of which involve the quick cooling of lava.
