Question

Quizplus · Accepted Answer

The condition described is the greenhouse effect, which is caused by the buildup of carbon dioxide in the atmosphere from burning fossil fuels. This traps heat and causes global warming. A is incorrect because pollution is a broader term and not specific to the cause of global warming. B is incorrect because superfund is a term used for sites in the United States that are contaminated with hazardous waste. D is incorrect because acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, not carbon dioxide.
