General KnowledgeGeography
- A1 only
- B2 only
- CBoth 1 and 2
- DNeither 1 nor 2
Explanation
Water vapour plays a central role in atmospheric stability and instability: condensation releases latent heat that drives convection, cloud formation and storms — statement 1 is correct. It is also the most important greenhouse gas, absorbing outgoing long-wave radiation like a blanket so that the Earth neither becomes too hot by day nor too cold by night — statement 2 is correct. Hence both.
