Igneous Rocks: Born from Fire! | Geology 101

How do igneous rocks actually form? In this fast geology lesson, we explain the difference between intrusive (plutonic) and extrusive (volcanic) igneous rocks and show how cooling magma and lava create familiar rocks like granite, basalt, and obsidian. You’ll learn what controls crystal size, why some igneous rocks form deep underground while others erupt at the surface, and how these rocks fit into the bigger rock cycle. 🌋 What you’ll learn: • Intrusive vs extrusive igneous rocks • How magma and lava cool and crystallize • Why texture tells you where a rock formed • Examples of common igneous rocks • How igneous rocks fit into the rock cycle Perfect for geology students, Earth science fans, or anyone curious about how rocks form.
