Fracking

The process of fracking involves all the following EXCEPT

• drilling down through shale rock to areas where natural gas is trapped

• using high pressure water with chemicals to release the natural gas

• using a traditional oil well to pump out the natural gas from the air pockets

• the natural gas will be pumped out through the same well as the water and chemicals

In the United States, fracking was able to

• increase US gas production which helped bring down fossil fuel costs

• increase US gas production which helped increase the cost of fossil fuels

• increase US gas production which helped increase the use of coal

• increase US gas production which helped increase the US's dependence upon foreign oil

Slickwater that is used in the process of fracking may contain

• water

• detergents

• sand

• all of these

Which of the following is NOT an environmental problem associated with fracking?

• increased number of earthquakes in fracking areas

• increased levels of methane gas in the atmosphere around fracking sites

• increased levels of oil spills in fracking locations

• groundwater contamination in some areas near fracking sites

Some chemicals released during the fracking process could lead to reproductive problems. This would mean these chemicals may act as

• neurotoxin

• cardio disruptor

• endocrine disruptor

• gastrointestinal disruptor
