A volcano is a type of mountain that emerges from the earth’s crust through which lava, volcanic ash, and gases escape. A volcano becomes active when it erupts. An eruption is when lava and gas are released from a volcano. Volcanoes emit rocks that can reach 4-200 kilometres high. Volcanoes also emit lava which can reach temperatures between 700-1,300° celsius.
