Porosity refers to the amount of pore space within a rock or sediment, while permeability refers to how easily fluids can flow through the rock or sediment. A rock or sediment can have high porosity if there are many pore spaces, but if those pore spaces are not well connected to each other, then fluids cannot easily flow through them, resulting in low permeability.
