Igneous Rocks - Geology (U.S ... - National Park Service

Extrusive Igneous Rock. Extrusive, or volcanic, igneous rock is produced when magma exits and cools as lava at or near the Earth's surface. Exposed to the relatively cool temperatures of the atmosphere, the lava cools quickly meaning that mineral crystals don't have much time to grow. This results in rocks with a very fine-grained or even ...
