Question

Fracking opens cracks that exist in underground rock, allowing gas to escape back up through the well. Which statement best describes an environmental consequence of this process?
A Wastewater is contaminated with oil and becomes sludge in landfills.
B During natural gas extraction, methane escapes into the atmosphere.
C Water vapor is released into the air, which is considered a greenhouse gas.
D Heavy metals are released into surrounding soil, poisoning local vegetation.

Answer 1

Answer:

During natural gas extraction, methane escapes into the atmosphere.

Explanation:

hint "allowing gas to escape back up to well" the gas that escapes us is methane which is bad for the atmosphere.

Answer 2

The correct answer as to the environmental consequence of allowing gas to escape back up through the well during the process of fracking is that methane escapes into the atmosphere. The correct option would, therefore, be B.

• During fracking, liquid and materials are injected into the ground at high pressure to create fractures in the ground and safely extract energy from an already existing underground well.

• Sometimes, cracks are also created in underground rocks as a result of fracking, thereby allowing a gas such as methane to find its way into the atmosphere.
• Methane gas is one of the greenhouse gases that can cause the warming of the planet.

Hence, gas extraction through fracking has the potential to cause methane to escape into the air.
