Which term describes pumping water at high pressure to break apart rocks to release natural gas?

• A. Fracking
• B. Hydroelectric Power
• C. Solar Power
• D. Wind Energy

Answer: (A)

That process is hydraulic fracturing, commonly called fracking. It involves pumping water mixed with sand and additives into deep rock formations at very high pressure. The pressure creates and enlarges cracks in the rock, allowing natural gas trapped in the rock to flow into the well and be collected. Fracking has increased gas production in many areas, but it also raises concerns about groundwater safety, methane leaks, and induced seismicity, so regulation and careful practices are important. The other energy methods—hydroelectric, solar, and wind—do not involve fracturing rocks; they generate power from water flow, sunlight, or wind, respectively.
