A.
Permeable, non-permeable and permeable
B.
Non-permeable and permeable
C.
Permeable and non- permeable
D.
Non-permeable, permeable and non-permeable
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
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.
