What is the volume of voids of open space in a rock or unconsolidated material?
Porosity is the volume of open spaces in rock or soil.
What does it mean if a rock has a high porosity?
Sedimentary rocks are composed of clasts or grains that have been pressed together. The gaps or spaces between these grains are known as pores or pore spaces. As such Porosity is a measurement of the volume of pore space compared to the total volume of the rock and is usually expressed as a percentage. As such a rock that has a high porosity has a very large amount of pore space compared to its total volume. For example a rock with a porosity of 50% would essentially be composed of 5o% solid material and 50% empty space (whcih may in turn be filled with fluid or gas or a mixture of the two.
The air spaces between rock and soil particles are called?
pore space
Is groundwater oil and natural gas commonly found within pore spaces in sedimentary rocks?
Groundwater, oil, and natural gas are commonly found in these spaces in sedimentary rock?
What is the process in which minerals precipitate into pore spaces between sediment grains and bind sediments together to form rock?
a.cementation b.compaction c.conglomerate d.weathering
What is the volume of voids of open space in a rock or unconsolidated material?
Porosity is the volume of open spaces in rock or soil.
Can a rock have small spaces but not allow water to flow through?
Yes, it can have porosity, or pore spaces, but may not have permeability, or the ability for a fluid to flow through connected pore spaces.

What is porosity in relation to groundwater?
Porosity is a measurement of the ratio of pore space to solids in a given volume of material. The pore spaces form in soils and rocks due to the gaps between the individual clasts or grains that aggregate to form them. Compaction and consolidation (where the soil or rock is compressed) can force the grains closer together and so reduce the size of the pore spaces and so decrease the porosity. Below the phreatic surface or water table, these pore spaces are normally filled with water (there are exceptions however for simplicities sake it is a reasonable assumption). The larger the porosity of a rock or soil, the more space per unit volume there is to store groundwater. Also the larger the interconnections between the pore spaces and the greater the number of interconnections, the more permeable the material will be to the movement of groundwater. Porosity is a dimensionless quantity which is calculated by dividing the volume of void space by the total volume of the material in question. There are a number of methods of determining the value of the porosity of a material and for more information please see the related link.
What can explain the differences in elastic moduli between different specimens of the same rock species?
Porosity appears to be a very significant parameter in the stiffness of a given rock type. Porosity essentially describes the amount of open space within a given volume of rock and takes the form of spaces between the grains or crystals that compose the rock. This empty space is relatively easy to compress and so acts to reduce the stiffness (elastic modulus) of the rock. These void spaces tend to act as nucleation points for the formation of fractures which can therefore also reduce a rocks strength. Anything that acts to reduce this porosity will also increase the stiffness. Examples include the precipitation of cementing materials in the pore spaces and compaction which acts to increase the rocks density by "squashing out" the pore space increasing the solid volume of the material. Factors which may decrease a given rock types stiffness include weathering (where the rock's constituent minerals are broken down into new ones - commonly clay minerals which have a much lower stiffness than the original rock forming ones) and dissolution where minerals are dissolved by pore fluids forming voids / pore spaces within the rock which act to increase porosity and hence decrease stiffness.
The percentage of a rock's total volume taken up by pore space is called the?
Porosity
How can water travel through rock?
For water to flow through a rock, there must be gaps between the mineral grains or clasts in a sedimentary rock. These are known as pore spaces and rocks with these pore spaces are known as porous. As such the word porosity is used to describe the ratio between the pore spaces and the total volume of the rock. For water to be able to travel through the rock, these pore spaces must be interconnected. Rocks (or any other material) through which fluids can flow are known as permeable.
