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 does the word ground water mean?
ground water means water that is in a ground
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 the function of the skin in the respiratory system?
Take in oxygen through the pore spaces
What is the rate at which liquid passes through the pore spaces of a rock Surplus?
Permeability
What fills spaces between particles of and soil is called?
Groundwater fills spaces between particles of soil.
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 are the spaces called in between a pile of soil?
pore spaces
Why is water able to soak into the ground and collect as groundwater?
Pore spaces and other gaps in rocks allow water to pass through
What are the air pockets found in soil called?
Pore Spaces
What are the spaces between rocks and soil called?
Porosity or pore space
The air spaces between rock and soil particles are called?
pore space
What is the term of water under the ground that is a primary source of drinking water?
Groundwater The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from, and eventually flows to, the surface naturally. Groundwater is also often withdrawn for agricultural, municipal and industrial use by constructing and operating extraction wells.

What force pushes groundwater from pore to pore below the water table?
Pressure gradient or hydraulic gradient is the force that pushes groundwater from pore to pore below the water table. A boundary between saturated rock below and unsaturated rock above is the water table.
