... As magma rises toward the surface, the dissolved gas begins to expand as pressure decreases and this exerts an enormous upward force on the magma. When a volcano erupts, the force of the expanding gases pushes magma from the magma chamber through the pipe until it flows or explodes out of the vent. ...
