Detailed explanation-1: -Although the amount of water that can be stored in an aquifer depends on the porosity, it is the permeability of an aquifer that determines the rate at which ground water can move.
Detailed explanation-2: -The total volume of open space in which the groundwater can reside is porosity. Porosity determines the amount of water that a rock or sediment can contain. In sediments or sedimentary rocks the porosity depends on grain size, the shapes of the grains, and the degree of sorting, and the degree of cementation.
Detailed explanation-3: -The amount of water an aquifer can hold depends on the volume of the underground rock materials and the size and number of pores and fractures that can fill with water.
Detailed explanation-4: -About 1.7 percent of all of Earth’s water is groundwater and about 30.1 percent of freshwater on Earth occurs as groundwater. As the bar chart shows, about 5, 614, 000 cubic miles (mi3), or 23, 400, 000 cubic kilometers (km3), of groundwater exist on Earth.
