Hydraulic fracturing, or fracking, is used to extract natural gas trapped in shale layers thousands of feet below the surface. Drills go straight down a mile or more, then turn horizontally to reach gas pockets. Drillers then inject thousands of gallons of water and chemicals into the shale under high pressure to crack the rock and release the gas.
