Air and fluids.
sorry about spelling - porous rocks
groundwater
The bubbles and pores are from trapped gasses which expanded in the molten material as it neared the surface. They're usually found in extrusive igneous rocks, those that have solidified in the air or on the surface.
They rarely have pores. But sometimes they get them from all the heat and pressure their put under.
Saturated Zone .
It is called pore water pressure
groundwater
igneous rocks do absorb water because of all the pores ,cracks, and holes in them. The holes will absorb the water and the water will get trapped in the rock there for igneous rocks do absorb water.
when water freezes, it expands. when water freezes in cracks and pores of rocks, the force of its expansion is strong enough to split the rocks apart.
Water can get into fractures/joints/pores of rock, freeze, and then expand, weathering the rock.
No, a zone of saturation forms when water fills the pires in rocks
