Igneous rocks form when hot, molten rock crystallizes and strengthens. Lava that climbs to the surface is called lava. Igneous rocks are classified into 2 groups depending on where the molten rock solidifies: Intrusive or extrusive. Mafic: Derived from words magnesium and ferric to define an igneous rock having bountiful dark-colored, magnesium- or iron-rich minerals such as biotite, olivine, or pyroxene. Extrusive, or volcanic, igneous rock is created when magma leaves and cools as lava at or near the Earth's surface. Subjected to the relatively cool temperature levels of the ambience, the lava cools down promptly implying that mineral crystals don't have much time to grow. Volcanic procedures has shaped the extrusive igneous rock formations at these parks: Hawai'i Volcanoes National Park, Hawai'i [Geodiversity Atlas] [Park Home] Sunset Crater Volcano National Monument, Arizona [Geodiversity Atlas] [Park Home] Crater Lake National Park, Oregon [Geodiversity Atlas] [Park Home].
