This set of MCQs helps students to learn about atmosphere & greenhouse gas which is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect and can cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution.
