Hydraulic fracturing is a process that Blank______.Multiple choice question.allows us to extract oil from conventional oil depositsreleases oil from "tight" geologic formationsuses the natural gas that is typically found on top of oil deposits

Hydraulic fracturing is a process used by gas companies to rupture and collects pockets of gas trapped within pockets of shale rock. A particular shale fracking site is  in length and occupies an area of . How wide is this particular site?

Write the scientific term:1. A gas that is produced during the formation of oil and trapped inpockets within rock layers below the earth's surface.(............................)2. A process uses pressured fluids to break layers of shale rocks andforce out the trapped natural gas, which can be collected andtransported(............................)Put (true) or (false):1. Natural gas is also known as methane gas. ( )2. Fracking fluids are good for underground water. ( )3. Methane gas is one of the greenhouse gases that are good for theenvironment.( )Give a reason for each of the following:a) Natural gas burns cleaner than coal, yet it is considered a pollutant.

Almost 20 years after the adoption of hydraulic fracturing began to supercharge U.S. production of oil and gas, there’s growing evidence of a correlation between the industry’s activities and an array of health problems ranging from childhood cancer and the premature death of elderly people to respiratory issues and endocrine disruption. While the oil and gas industry insists its processes are safe and regulators have set rules designed to prevent the contamination of air and water by “fracking” technology, _________15Mark for ReviewMCQABCWhich choice most logically completes the text? Athe nonprofit Physicians for Social Responsibility and Concerned Health Professionals of New York, published its most recent compendium of investigations into risks and harms linked with fracking.Bafter the continuing challenges of exposure assessments, the results of recent studies confirm and extend the validity of earlier findings.Cadvocates for stricter limits on the practice, or even an outright ban, point to an increasing number of studies suggesting that fracking poses a threat to public health.D79 percent of U.S. natural gas and 65 percent of crude oil is now produced by fracking, with more than 17.6 million people living within a mile of a fracked oil or gas well.
