5005 Praxis Practice Test Practice Question
Natural gas-fired power plants are considered greenhouse gas emitters because the burning of natural gas produces which of the following?
Correct Answer: C
Rationale: Natural gas combustion primarily produces carbon dioxide (CO2), a significant greenhouse gas contributing to climate change. This makes option C the most relevant choice.
Option A, hydrogen, is not a greenhouse gas and is often a byproduct of various processes rather than a direct emission from burning natural gas. Option B, radon, is a naturally occurring radioactive gas but is not produced from natural gas combustion. Lastly, option D, helium, is an inert gas that does not contribute to greenhouse effects and is not a product of burning natural gas. Thus, CO2 is the primary concern in discussions about greenhouse gas emissions from natural gas-fired power plants.
