Subsequently, one may also ask, is Chalk porous or permeable?
Chalk is weaker than granite and tends to form more gentle rolling hills and valleys. Chalk is porous and permeable, so there is very little surface water and valleys formed in earlier times are now largely 'dry'.
why is chalk classified as a porous rock? Chalk is highly porous, so water flows rapidly between the grains. The porosity of a rock is the proportion of the rock that is made of the spaces between the grains (known as pores), voids and cracks.
Herein, what rocks are permeable?
Permeable rocks include sandstone and fractured igneous and metamorphic rocks and karst limestone. Impermeable rocks include shales and unfractured igneous and metamorphic rocks.
