Fracking uses highly pressurized fluids, such as water mixed with sand and chemicals, to drive open cracks that exist in underground rock. Which statement
best describes an environmental consequence of this process for ecosystems?
O Wastewater is contaminated with oil and becomes sludge in landfills
O Water vapor is released into the air, which is considered a greenhouse gas,
Heavy metals are released into surrounding soil, poisoning local vegetation
O Billions of gallons of water are pulled from surrounding areas

Answer:

the answer is A

Step-by-step explanation:

Fracking is a method of drilling fossil energy resources, which requires a lot of water and consumes local water resources. It is pumped with high pressure water, sand and chemicals, causing high pressure to block the porous rock and release gas.

The water spill itself destroys nature from the drilling site, and may even cause earthquakes, especially due to the pumping of abundant wastewater into porous rock types such as limestone. For example, Oklahoma appears to have become a special earthquake risk area. The biggest impact of water distortion is on groundwater. In Wyoming, USA, the same chemicals found in groundwater have been found in groundwater, and some of them are toxic or carcinogenic.

The correct answer is that chemicals added to the liquid can contaminate groundwater.
