Question

Hydraulic fracturing, commonly known as fracking, is a method of extracting natural gas and oil from deep within the Earth. It involves injecting a high-pressure fluid, typically a mixture of water, sand, and chemicals, into underground rock formations to create fractures, allowing the release of hydrocarbons trapped in the rock. The sand helps to prop open the fractures, enabling the extraction of fossil fuels. Fracking has been a significant development in the energy industry, unlocking access to previously inaccessible reserves. However, it is a controversial practice due to concerns about its environmental impact, including potential groundwater contamination, induced seismic activity, and the release of methane, a potent greenhouse gas. The debate surrounding fracking revolves around balancing energy needs with environmental and public health considerations.

Which of the following affects the quantity of water that is available during the fracking process?Water is withdrawn from low-supply areas.
Water is withdrawn from low-supply areas.

Water is mixed with chemicals leaches into the groundwater.
Water is mixed with chemicals leaches into the groundwater.

The high water pressure generates small-scale earthquakes.
The high water pressure generates small-scale earthquakes.

methane makes the water supply flammable.

Answer 1

"Water is withdrawn from low-supply areas."

Explanation: large volumes of water used for fracking reduce local water availability. The other choices describe impacts on water quality (chemicals or methane contamination) or induced seismicity, not the quantity of water available.
