Answer:
Porosity
Explanation:
Porosity is the ratio of volume of pores to the total volume of soil. This ratio varies between 0 and 1, or between 0% and 100% as a percentage.
Porosity is also called as void fraction and is a measure of the empty spaces present in a material. Thus a porous soil will have more amount of air and less porous soil will have less amount of air
A porous soil is made from coarse particles that leave large gaps known as pores.
