There are several different stages of volcanoes such as active volcanoes that erupt often times a year, erupting volcanoes that are in the process of spewing lava, a dormant that isn't erupting at the moment but will eventually, and an extinct volcano that wont be erupting anytime soon or ever.
Volcanoes are just mountains that have hot magma sitting the in a chamber but when it erupts then it becomes lava. Volcanoes erupt due to friction when the earths plates slide against each other. An erupting volcano can cause other natural disasters such as earthquakes, flash floods, tsunamis, etc. There are also different types of volcanoes like cylinder cones, composite volcanoes, shield volcanoes, and lava volcanoes.
