1. Molten rock (magma or lava): This is the fundamental ingredient. Igneous rocks are formed from the cooling and solidification of molten rock material.
2. Cooling and solidification: Molten rock must cool down and solidify to become a solid rock. This can happen either:
* Below the Earth's surface: Magma cools slowly and forms intrusive igneous rocks with large crystals.
* On the Earth's surface: Lava cools quickly and forms extrusive igneous rocks with smaller crystals.
