Pumice and scoria differ from obsidian by having abundant vesicles - cavities in the rock produced when gas bubbles were trapped in a solidifying melt. Some of the gases which cause the explosive eruption get trapped in the magma and form gas bubbles. Trapped gases occupy much larger volume than they did when dissolved in magma.
