Final answer:
Permeability determines how easy it is for water to flow from one pore to the next, from areas of higher elevation to areas of lower elevation.
Step-by-step explanation:
Permeability determines how easy it is for water to flow from one pore to the next, from areas of higher elevation to areas of lower elevation. Permeability is a property of rocks or soils and refers to their ability to transmit fluid. Rocks with high permeability, such as well-sorted sedimentary rocks, allow water to pass through easily, while rocks with low permeability, such as igneous and metamorphic rocks, restrict the flow of water.
