igneous rock formations
Cooled magma structures
Igneous rock formations are geological structures created when molten rock cools and solidifies.
When magma cools slowly underground, it forms intrusive formations like granite batholiths and dikes.
When lava cools quickly at the surface, it creates extrusive formations like basalt columns and volcanic domes.
The igneous rock formations in Yellowstone attract geologists from around the world.
