When the ratio of the gases becomes more in magma it causes the magma to disintegrate into pyroclasts, a combination of partially molten and solid fragments, and the volcano erupts explosively. chamber that is already brimming with magma of similar or different compositions.
If the magma reaches the surface it is called lava and lava accumulates to make a volcano.   Volcanoes grow by intrusion and extrusion. An intrusion is magma that moves up into a volcano and then it stops, never erupting.This way the volcano grows on the inside. An extrusion is an eruption.It can add layers of lava or ash. This way the volcano grows on the outside.   Volcanoes erupt because of density and pressure. The lower density of the magma causes it to rise (like air bubbles in syrup).rash, greenhouse gases, almost anything.
