Question

Most of the wastewater produced by fracking is pumped back to the surface where it is stored in artificial ponds. Wastewater is diluted with fresh water and pumped back into the ground to shatter more shale. After several uses, the water can no longer be used and is sent to specialized treatment facilities. This process uses millions of gallons of fresh water each year, often in regions where water availability is already a problem.Select all statements that apply to the process of hydraulic fracturing, or "fracking."A). Wastewater from hydraulic fracturing is absorbed into the shale indefinitely.B). Hydraulic fracturing allows geologists to capture natural gas stored in the pore spaces of shale.C). Some large magnitude historic earthquakes can be traced to the use of hydraulic fracturing.D). Hydraulic fracturing threatens the supply of other natural resources.E). Once the shale is shattered, fractures remain open due to the inherent strength of the shale.

Answer 1

Answer:

B). Hydraulic fracturing allows geologists to capture natural gas stored in the pore spaces of shale.

C). Some large magnitude historic earthquakes can be traced to the use of hydraulic fracturing.

Explanation:

Hydraulic chipping is a soil drilling technique that allows access to gas reservoirs that are stored at very intense depths. This technique consists of making perforations in the extremely deep shale with the help of a pipe that pours a mixture of water, chemical solvents and sand that cause pressure in the shale forming fissures that release the natural gas that is captured in the atmosphere. In addition, this mixture of solvents and sand prevents cracks from closing and more gas is captured.

This technique is very controversial because many people claim about the strong natural impact and the polluting capacity it has. In addition, areas where this technique was used are associated with high intensities of seismic shocks.
