⚫️$\bold{What\:are\:igneous\:rocks}$

Igneous rocks are formed from the solidification of molten rock material.

⚫️$\bold{There\:are\:two\:basic\:types}$

⚫️$\bold{Intrusive\:igneous\:rocks}$crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form. Examples of intrusive igneous rocks are diorite, gabbro, granite, pegmatite, and peridotite.

⚫️$\bold{Extrusive\:igneous\:rocks}$ erupt onto the surface, where they cool quickly to form small crystals. Some cool so quickly that they form an amorphous glass.

⚫️These rocks include andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria, and tuff
