Shale is not Porous because it is a sedimentary rock.,
of course it's not true ,shale is a porous rock but it's pores are not connected in other words it's not permeable .here is a reason for that:

(to a depth of 50 ft the formation is made of shale and it's porosity is around 50 percent

Why sandstone is more porous than limestone and shale?
because it's grains aren't interlocking
Why might sandstone act as a reservoir for ground water or oil well shale?
Sandstone is extremely porous and absorbs liquids like a sponge.. Shale is nearly impervious to liquids.
Where is precipitation stored between or within the rocks?
Yes. It will depend on the type of rock. For a porous rock,such as sandstone or shale, the water can be within the rocks. For non-porous rocks it will be stored between the rocks.
Why mud cake is make with sandstone rather than shale?
because sandstone is a porous media meaning it have a lot of pores then mud filtrate (its water) can enter the rock but the solids of the mud cant hence mud cake form.shale is a porous media too but its pores not connected together so mud cant enter the shale and mud cake don't form.
How can something be porous but also impermeable?
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 do you make oil out of shale?
You don't make oil from shale, you extract oil from shale. The shale acts like a sponge, sometimes the shale is so porous that the oil can be squeezed or sucked out, otherwise it can be extracted by crushing and heating the shale.
Why can water pass easily through sandstone but not shale?
Because sandstone has wider particles than shale and this let's the water through.
Is shale magnetic?
no shale is not magnetic
Is shale an element?
No. Shale is a mixture.
Is shale gas found under the see?
It can be. It is found in a rock type called shale and is produced in the shale form the original bio mater included in the deposition of the shale. If a unit of shale lithology is to be found on the continental shelf strata then it is likely that that shale will contain shale gas and it will be under the sea.
What is metamorphic shale?
The Shale is not a metamorphic rock it is a sedimentary rock.
Is a concrete non porous?
There are two types porous and non porous. You can also seel porous concrete to make it non porous.
