Believe it or not, some porous rocks are considered impermeable. No rock is completely impermeable, but some porous rocks like shale and pumice are mostly impermeable, because the pores are not interconnected, thus not allowing fluids or gases to pass through them. This is why shale makes a good cap-rock, and pumice floats instead of sinking.

How is petroleum stored in ground formations?
Petroleum occurs in porous and permeable rock which is surrounded by less porous and impermeable rock which prevents or slows its eventual escape to a body of water or the surface.
What rocks are impermable?
As a general rule, igneous rocks are impermeable. Metamorphic rocks may also be impermeable, but this will depend on the mineralogy and level of metamorphism. These rocks are impermeable because they have crystals which interlock, forming a watertight structure. This is the rule, but there are exceptions. Sedimentary rocks tend to be permeable or porous, and many will even dissolve, or their cement will dissolve in water. This is because of their often clastic structure which has some holes in it.
What type of rock is groundwater found in?
Usable groundwater is to be found in aquifers. Aquifers are porous, permeable rocks sandwiched between two layers if impermeable rocks. Sandstones and porous limestones can form good aquifers.
Is concrete a non-porous surface?
There are two types porous and non porous. You can also seel porous concrete to make it non porous.
What is a rock called which is very hard and non porous and crystals in the layers?
Because the molecular lattice is tighter and smaller than waters molecular lattice making it impermeable
What is the opposite of porous in science?
impermeable or non-porous.
Is an aquitard porous or impermeable?
it has to be impermeable so it can line the aquifer without letting water straight through
What does non-porous mean?
Porous means 'with holes'. So non-porous means 'without holes'
Is granit a porous rock?
The crystals of granite are very tightly interlocked. This means that granite is not a very porous type of rock.
Water cannot pass through solid rock because it is?
The rock is impermeable (not porous).
How can a material be porous but also impermeable?
A material can be porous but also impermeable due to its surface structure. The molecular level can allow molecules of air to pass through, but not water molecules.many materials, such as GoreTex, has a surface structure, that at a molecular level can allow molecules of air to pass thru but not molecules of water. This way, you can be protected from falling rain, but also have a material that will "breathe" and wont keep you feeling muggy inside.

What is the difference between impervious and impermeable?
In a simple Language:::: Impermeable rocks which r neither porous nor permeable.ex: Aquifuge(granite,Quartzite) Impervious rocks which r porous bt not permeable(hvng storing capacity bt not allow easy and quick flow through it)...ex: aquiclude(clay beds) - Nits(nits.geologist@gmail.com)
What are permeable and impermeable rocks?
Permeability is a measure of how well a porous media transmits a fluid. It has nothing to do with the fluid itself. It is measure in (length)2. The Hydraulic Conductivity is a measure of how easily water moves through the porous media. It depends on the permeability of the matrix, but also is a function of the fluid. It is a measure of (length)/(time)
What type of rock is groundwater found in?
Usable groundwater is to be found in aquifers. Aquifers are porous, permeable rocks sandwiched between two layers if impermeable rocks. Sandstones and porous limestones can form good aquifers.
What is the word meaning something without holes?
Impermeable.
