GEOLOGY

Detailed explanation-1: -An aquifer is a body of rock and/or sediment that holds groundwater. Groundwater is the word used to describe precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground. There are two general types of aquifers: confined and unconfined.

Detailed explanation-2: -Permeability refers to how easily water passes through sediments and rock. Permeability is a function of the size of pore openings. If sediments are well sorted, pore spaces are uniformly sized, thereby allowing for groundwater flow readily between individual sediment particles.

Detailed explanation-3: -Figure 2 is a simple cartoon showing three different types of aquifers: confined, unconfined, and perched. Recharge zones are typically at higher altitudes but can occur wherever water enters an aquifer, such as from rain, snowmelt, river and reservoir leakage, or from irrigation.

Detailed explanation-4: -When a water-bearing rock readily transmits water to wells and springs, it is called an aquifer. Wells can be drilled into the aquifers and water can be pumped out. Precipitation eventually adds water (recharge) into the porous rock of the aquifer.

Detailed explanation-5: -water level. artesian basin. artesian spring. sinkhole.
