As precipitation infiltrates into the subsurface soil, it generally forms an unsaturated zone and a saturated zone. In the unsaturated zone, the voids-that is, the spaces between grains of gravel, sand, silt, clay and cracks within rocks-contain both air and water. Although a lot of water can be present in the unsaturated zone: why can't this water be pumped by wells A) Soils, like clay, absorb water quickly
B) Sinkholes collect water above the water table.
C) Land with no slope lets water runoff at a fast rate.
D) If its not any of the other its this
