Q. Sulfur hexafluoride and CFC-11 both affect radiative forcing to the same degree. Why is sulfur hexafluoride's GWP five times greater than that of CFC-11?
Sulfur hexafluoride has a significantly shorter residence time than CFC-11.
Both compounds have similar residence times, but only sulfur hexafluoride absorbs infrared radiation.
Both compounds have similar residence times, but only CFC-11 absorbs infrared radiation.
Sulfur hexafluoride has a lifetime of 3200 years, while CFC-11 has a lifetime of 45 years
Both compounds have similar residence times, but only sulfur hexafluoride re-emits long wave radiation

Q. Which statement about the sulfur cycle is true?
Sulfur compounds in the atmosphere have a short residence time due to oxidation reactions.
The atmosphere is the largest sulfur reservoir on earth.
The mean residence time for a sulfur molecule in the sea is 123 years.
Large volcanic eruptions increase global temperatures because they emit sulfur.
Sulfur found in the earth's crust comprises a minor portion of the earth's sulfur budget.
