Porosity and Permeability Quiz

What is the main difference between porosity and permeability?

• Porosity is the ability of a material to hold water, while permeability is the ability to allow water to flow through.

• Porosity and permeability are the same thing.

• Porosity is the color of the soil, while permeability is the size of the grains.

• Porosity refers to the size of the grains, while permeability refers to the color of the soil.
