Porosity refers to the amount of pore space within a material, while permeability refers to the ability of fluids to flow through that material. Materials can have high porosity but low permeability if the pore spaces are not interconnected or are blocked, which would inhibit fluid flow. Conversely, materials with high permeability typically have interconnected pore spaces that allow fluids to flow easily.
The permeability and porosity of an aquifer is very high, air and pretty much any liquid can pass trough it with ease. Where as shale has very little porosity making it virtually impossible for air or liquid to pass through.
Earth materials vary in their capacity to hold water due to differences in their porosity and permeability. Porosity refers to the amount of pore space within a material, while permeability describes how easily water can flow through it. Materials with high porosity and permeability, such as sand and gravel, can hold more water compared to materials with low porosity and permeability, such as clay and bedrock.
Permeability/ hydraulic conductivity.
Composition, porosity, permeability, and particle size are used to describe different characteristics of sedimentary rocks. Composition refers to the minerals and materials present in the rock, porosity measures the amount of space between particles, permeability measures the rock's ability to allow fluids to flow through it, and particle size refers to the size of the individual grains or particles that make up the rock.
The sample with the largest pore size and highest porosity will typically have the greatest permeability. Materials such as sandstone or gravel with well-connected, large pores will allow fluids to flow more easily through them, resulting in higher permeability.

The porosity directly correlates with the permeability because the permeability requires a certain level of porosity for a certain measure of it.
Porosity refers to the empty spaces or voids in a material, while permeability is the ability of a material to allow fluids to flow through it. Higher porosity means more empty spaces, but that doesn't always translate to good permeability; permeability also depends on the connectivity of these pores.
Porosity refers to the amount of pore space in a material, while permeability is a measure of how easily fluids can flow through a material. High porosity indicates more space for fluids to be stored, while high permeability indicates easy flow of fluids through the material.
Texture refers to the size, shape, and arrangement of particles in a material. Porosity is influenced by the amount and size of pore spaces between particles, which in turn affects permeability. Finer textures with smaller particles typically result in higher porosity but lower permeability, while coarser textures with larger particles usually have lower porosity but higher permeability.
Permeability refers to the ability of a material to allow fluids to flow through it, while porosity is a measure of the empty spaces (pores) within a material. In other words, permeability describes how easily fluids can move through a substance, while porosity describes the amount of open space within that substance.

Porosity is the amount of void space in a rock or other earth material (like a sand deposit) - in other words, it´s how much water a material can hold. Permeability refers to how well water flows through a material - that´s controlled by how large the pores are, and how well connected they are.
The sample with the largest pore size and highest porosity will typically have the greatest permeability. Materials such as sandstone or gravel with well-connected, large pores will allow fluids to flow more easily through them, resulting in higher permeability.
moderate porosity, low permeability.
