Igneous Rock

Igneous Rock- Igneous rocks formed from lava. It starts when lava starts seeping out of the Earth's crust. Then the lava starts cooling and hardening. Soon after that, the Igneous rock has formed. Igneous rock can form above or below ground. When it forms above ground, it is called Extrusive Igneous rock. When it forms below ground, it is called Intrusive Igneous rock. The Igneous rock forms faster above ground instead of below ground. It forms faster above ground because there's more wind which makes it cool faster.
