GEOLOGY

Detailed explanation-1: -Pore space is defined by porosity of a material possessing free space between the mineral grains, expressed as percentage (Rebollo et al., 1996), and depends on size and sorting of the particles as a cubic or hexagonic package.

Detailed explanation-2: -Porosity: is a measure of the void spaces in a material. Permeability: a measure of the ability of a material (such as rocks) to transmit fluids. Porosity and permeability are related properties of any rock or loose sediment. Both are related to the number, size, and connections of openings in the rock.

Detailed explanation-3: -Porosity is the pore space in soil between mineral particles (and solid organic matter) filled with either air or water. The pore space both contains and controls most of the functions of soil.

Detailed explanation-4: -Porosity or void fraction is a measure of the void (i.e. “empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%.

Detailed explanation-5: -Porosity is the percentage of void space in a rock. It is defined as the ratio of the volume of the voids or pore space divided by the total volume. It is written as either a decimal fraction between 0 and 1 or as a percentage. For most rocks, porosity varies from less than 1% to 40%.
