Describe the process of forming igneous rocks
WebIgneous rocks are formed from the solidification of molten rock material. Some form below Earth's surface. Some form on or above Earth's surface. We describe these two basic types: Intrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form. Examples of intrusive igneous rocks ... WebThe separation of minerals by mechanisms such as crystal settling result in igneous rocks having a wide variety of compositions.
