A molten rock that results from magma escaping to the surface during a volcanic eruption, which then flows before solidifying into volcanic rock.
The viscous material expelled from a volcano, characterized by its high temperature and fluidity, which eventually cools and hardens to form solidified volcanic formations.
A hot, flowing substance that originates from beneath the earth's crust, emerging through fissures in the ground and transforming into a solid state upon cooling.
Example:
その火山は溶岩を流し出した。
A movement of molten rock that emerges from a volcanic vent and travels across the surface, often solidifying into rock as it cools.
A geological formation created by the solidification of molten rock that has flowed from a volcano, resulting in a distinct structure on the terrain.
