What 2 processes are involved with the formation of an igneous rock?

The formation of igneous rock involves two key processes: crystallization and cooling. Crystallization occurs when molten rock material, or magma, cools and solidifies, leading to the formation of mineral crystals. This process can happen either beneath the Earth's surface, resulting in intrusive igneous rocks, or on the surface following a volcanic eruption, leading to extrusive igneous rocks. The rate of cooling influences the texture and mineral composition of the resulting rock.
