Some rocks have holes in them because they come out of a volcano as lava and the lava starts to harden but it doesn't turn into a rock straight away but the bubble of air pop leaving a whole so when the rock hardens its stays with all the hole.

∙ 12y agopressured molten stone material coming to the surface (in vulcanos) sets free only small amounts of enclosed gases which expand in the lack of pressure. Then the stone material cools down an keeps the gas bubble structure before all gas escapes.
Big amounts of contained gas would more like let the stone material explode.
