Question

What is the lower region of groundwater where all the pores in a rock or sediment are filled with water?

Answer 1

But rocks have different porosity and permeability characteristics, which means that water does not move around the same way in all rocks below ground. When a water-bearing rock readily transmits water to wells and springs, it is called an aquifer. Wells can be drilled into the aquifers and water can be pumped out.
