Water vapour is a highly variable atmospheric gas whose concentration generally decreases with altitude, and it also varies geographically, ranging up to about 4 per cent by volume in warm, humid tropical regions to less than one per cent in cold, dry desert and polar areas. Both given statements accurately describe this variability, making 'Both 1 and 2' the correct choice.
