GEOLOGY

Detailed explanation-1: -Permeability refers to how connected pore spaces are to one another. If the material has high permeability than pore spaces are connected to one another allowing water to flow from one to another, however, if there is low permeability then the pore spaces are isolated and water is trapped within them.

Detailed explanation-2: -If the open spaces in the rock layer are connected, water can move through the rock. A rock’s ability to let water pass through is called permeability. Rock that water cannot flow through is called impermeable.

Detailed explanation-3: -Mathematically, it is the open space in a rock divided by the total rock volume (solid and space). Permeability is a measure of the ease of flow of a fluid through a porous solid. A rock may be extremely porous, but if the pores are not connected, it will have no permeability.

Detailed explanation-4: -The ability or attribute of any soil or rock to permit the flow or passage of water through it is termed permeability.

Detailed explanation-5: -Porous and permeable materials include soil (if not too clay rich), sand, sandstone, limestone, fractured igneous and metamorphic rock, vesicular basalt and scoria. Impermeable and/or non-porous materials include clay, shale, non-fractured igneous and metamorphic rocks.
