Ques: Answer the following question given this paragraph: Greenhouse gases trap heat in the atmosphere. This is essential so that Earth has a more moderate temperature. Without greenhouse gases, nighttime temperatures would be frigid. Natural greenhouse gases include carbon dioxide, methane, water vapor, and ozone. CFCs and some other man-made compounds are also greenhouse gases. Human activities may increase the amount of greenhouse gases, like carbon dioxide, in the atmosphere. Q: What type of gases trap heat in the atmosphere, causing earth to have a moderate temperature? Choices: - ozone gases - carbon monoxides - sulfuric gases - greenhouse gases A:
Ans: greenhouse gases
