Volcano
火山
The word volcanoes is derived from the Roman god of fire Vulcan (Latin Vulcanus). Volcanoes are vents or holes where hot inner materials of the Earth (such as gases, crystals and molten rocks) are let out. The molten rock material in the crust under the volcano is known as magma. Lava, on the other hand, is the name given to the molten rock that gets out of the volcano. Igneous rock is formed when molten rock solidifies.
