Answer
Hydraulic fracturing, or fracking, is a technique used to extract oil and natural gas from shale rock formations. It involves injecting a high-pressure mixture of water, sand, and chemicals into the rock to create fractures. These fractures allow the trapped oil and gas to flow more freely and be extracted from the rock. Hydraulic fracturing is used in circumstances where traditional drilling methods are less effective in recovering oil and gas from tight rock formations like shale.
