If surface heating is strong but the air is dry why will convectional clouds remain limited?
Answer and explanation
Correct answer: Because dry air has little moisture for condensation
Strong surface heating warms air and makes it rise, which supports convection. However, cloud formation also requires sufficient water vapour. Dry rising air may cool, but it is less likely to reach saturation quickly; therefore condensation and the growth of convectional clouds remain limited. Option B is incorrect because warming air generally lowers relative humidity rather than saturating it. Exam tip: for convectional clouds, check heating, uplift and moisture together.
