Sabancaya volcano erupting, Peru in 2017 A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. The process that forms volcanoes is called volcanism. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate ...

A volcano forms when magma beneath the Earth's crust forces its way to the surface. Alternating layers of solidified lava and pyroclastic materials (ash and cinders) build up the typical cone shape of a stratovolcano as they are ejected through the central vent during eruptions. volcano, Vent in the crust of the Earth from which molten rock ...
Aug 5, 2024 · A volcanic eruption is an eruption of molten rock, hot rock fragments, and hot gases through a volcano, which is a vent in a planet’s or satellite’s crust. Volcanic eruptions can cause disastrous loss of life and property.
