Answer:
Wastewater from fracking operations is injected into porous rock formations, which can induce seismic activity.
Step-by-step explanation:
- The environmental concerns of the fracking can be linked to the increase of the potential for the oil spills that harm the coil and the surrounding vegetation and can cause the earthquakes due to the high pressure that is used to extract the oil and the gas from the rocks and storage of the excessive wastewater on site.
