question: What would happen to the amount of ultraviolet radiation trapped in the atmosphere if the number of greenhouse gases were increased?
choices.text: more would be trapped less would be trapped
choices.label: A B
para: If there are more greenhouse gases in the atmosphere, more ultraviolet radiation will be trapped and the Earth will heat up.
