Solution(By Examveda Team)

In an artesian well, the rock-layer are generally found in Non-permeable, permeable and non-permeable order. Permeable layers of rock that store and transport water are called aquifers. While porosity and permeability usually go hand-in-hand, though some porous rocks are not permeable and some impermeable rocks are porous. Permeability is affected mostly by the size and arrangement of the grains in the soil.
