volcanic rock
Solidified magma stone
Volcanic rock is rock that forms when lava or magma cools and solidifies, either on Earth's surface or just below it.
Common types include basalt, obsidian, and pumice.
The term distinguishes these igniteous rocks from sedimentary and metamorphic varieties.
The Hawaiian islands are built almost entirely of volcanic rock.
