What cause volcanic eruptions?

A volcano erupts because there is mass pressure under it. In a volcano there is lava the lava has gasses that make the eruption. When there is to much it bursts the volcano.Ex.

Its like a soda can. When you shake the bottle the gasses or bubble in this case need to come out. So when you open it they burst out on your shirt.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
