Question 6

Write explanatory notes on the following:
(a) Formation of clouds;
(b) Relief rainfall.


This question was popular among the candidates. Their performance was good except that some of the candidates could not explain the formation of clouds properly. The expected points included:

- when the ground is heated by the sun
- there is evaporation and evapo-transpiration
- air rises to high attitude
- cooling of air with attitudes lead to saturation
- condensation takes place around hydroscopic nuclei
- there is coalescence of particles to form clouds.
