Porosity= Volume of void space/ Total volume of the solid

This is a good way for soil, If you have the initial volume of the soil then all you have to do to find the void space is saturate it with water. As long as you know the weight different between before and after saturation you can find the void space because we know that water's density is about 1g/cm^3.

So,

Porosity= ((mass of saturated soil - mass of original soil) Density of water) / Volume of original soil

This also works.

What are two factors about the particles in a rock have the greatest effect on the porosity of the rock?

Porosity refers to the measure of how much of a rock is open space. The two factors concerning particles in a rock that have the greatest effect on the rock's porosity are shape and distribution.


What three factors affect a materials porosity?

Three main factors that affect a material's porosity are its particle size distribution, packing arrangement of particles, and the presence of any voids or gaps within the material structure. Smaller particle sizes, looser packing, and higher presence of voids generally lead to higher porosity in a material.


What factors affect porosity?

The larger the particle size, the higher the porosity. Also keep in mind that angular particles have a higher porosity than round particles. *Good way to remember porosity is that the spaces between particles are "pore-like."


Does grain size determine the porosity of a sediment type?

Yes, grain size does affect the porosity of a sediment type. Generally, sediments with larger grain sizes have lower porosity due to smaller pore spaces between grains, whereas sediments with smaller grain sizes have higher porosity due to larger pore spaces. However, the packing arrangement of grains also influences porosity in addition to grain size.

What factors control the porosity of an aquifer?

The porosity of an aquifer is controlled by factors such as the size, shape, sorting, and packing of the sediment grains, as well as the presence of fractures and other openings in the rock. Additionally, factors such as the degree of compaction and cementation of the sediment grains can also influence porosity. The porosity of an aquifer is important as it affects the storage and movement of water within the subsurface.


How could you test the soil's porosity?

To test a soil's porosity, you can conduct a simple experiment by measuring the volume of water that a known mass of dry soil can absorb. Calculate the porosity by dividing the volume of water absorbed by the total volume of the soil sample, then multiply by 100 to get a percentage. Additionally, you can use a soil moisture meter to directly measure the porosity of the soil by inserting the probe into the soil and recording the moisture content.


Rhombohedral cleavage is displayed by the mineral named?

Calcite is the mineral that displays rhombohedral cleavage. Cleavage is the way a mineral breaks along certain planes of weakness, resulting in smooth, flat surfaces. In the case of calcite, it typically breaks along three cleavage planes at 75° and 105°, resulting in rhombohedral-shaped cleavage fragments.
