Answer 2

#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.

#There are three main types of volcano - composite or strato, shield and dome. Composite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and [lava] flows. ... Eruptions are explosive due to the thick, highly viscous lava that is produced by composite cone volcanoes.
