Answer with Explanation:
The amount of groundwater that can be stored will largely depend on the <em>"soil's permeability." </em>A permeable soil means that <u>it is easy for water to pass through the pores.</u> It has<em> </em><em>larger pores that are well-connected to each other</em> thereby allowing water to flow freely. This also allows the water to pass through the rocks, which then <u>increases its </u><u>porosity</u>. This also leads to an easier way to extract the groundwater.
