Deep inside the Earth, there is hot molten rock called P which comes up and collects in a chamber. When the pressure in the chamber builds up, P finds a release through an opening or a crack in the crust of the Earth, called volcano. When P erupts through volcano, it is called Q. The eruption constitutes of gases, pieces of rocks and Q that comes out from R, an outlet or a well-like opening in the Earth’s surface.
