GEOLOGY

Detailed explanation-1: -Answer and Explanation: b) Sandstone would be the best aquifer. Sandstone is a sedimentary rock, comprised of sand-size grains of minerals and rocks, that can hold water.

Detailed explanation-2: -Sandstone: Fine-grained rocks such as sandstone make good aquifers. They can hold water like a sponge, and with their tiny pores, they are good at filtering surface pollutants.

Detailed explanation-3: -Good aquifers are those with high permeability such as poorly cemented sands, gravels, or highly fractured rock. An aquitard is a body of material with very low permeability. In general, tightly packed clays, well cemented sandstones, and igneous and metamorphic rocks lacking fractures are good aquitards.

Detailed explanation-4: -Sandstones generally have good porosity and permeability, making a good well. Shales have poorer permeability and well yields are poorer. Geology plays an important part in the area of influence of a well and the spacing of two or more wells.

Detailed explanation-5: -Sedimentary rocks such as sandstone and limestone are good aquifers. Rocks that are impermeable make confining layers and prevent the flow of water. Examples of confining layers would be sedimentary rocks like shale (made from tiny clay and silt grains) or un-fractured igneous or metamorphic rock.
