Fracking (short for hydraulic fracturing) is the process of drilling  down into the earth to extract oil or natural gas from deep under ground. A high-pressure water mixture is then aimed at the rock to release the gas inside. A combination of water, sand, and chemicals are forced into the rock at a high pressure to allow the gas to flow to the head of the well.
