GEOLOGY

Detailed explanation-1: -Good examples of aquifers are glacial till or sandy soils which have both high porosity and high permeability.

Detailed explanation-2: -High porosity hair is hair that attracts and loses moisture easily. If you have high porosity hair, it means that water, oils, and other types of products can be easily absorbed by your hair, but because your hair is highly porous, it may not be able to retain moisture as well as other types of hair.

Detailed explanation-3: -The combination of water storage (porosity) and flow (permeability) makes a good aquifer-a rock unit or sediment that contains usable groundwater. Well-sorted sediments (i.e., uniform grain size) have higher porosity, because smaller sediment particles do not fill in the spaces between the larger particles.

Detailed explanation-4: -Clay is the most porous sediment but is the least permeable. Clay usually acts as an aquitard, impeding the flow of water. Gravel and sand are both porous and permeable, making them good aquifer materials.

Detailed explanation-5: -AQUIFER-a porous layer of sediment or rock WITH high permeability.
