Problem
Water vapour exists in variable amounts in the atmosphere, and it contributes to the greenhouse effect.
(1) In which part (or layer) of the atmosphere does water vapour ( H2Ovap ) exist in its largest concentrations?
(2) Suggest some natural origins of atmospheric water vapour.
(3) Suggest how water vapour concentrations in the atmosphere might be increased by human activities.
(4) How does the atmosphere remove water vapour?
(5) How would you expect an increase in water vapour concentrations in the atmosphere to affect the average surface temperature of the Earth?
