Observation

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.
