$1\mathrm{.}1$ Explain the process of cloud formation, including the role of condensation and the

conditions required for it to occur. Provide examples of how dynamic cooling

contributes to the formation of clouds.

$1\mathrm{.}2$ Differentiate between evaporation, transpiration, and evapotranspiration, and state

the factors influencing each process.

$1\mathrm{.}3$ Explain the various pathways water takes during its movement through the

hydrological cycle

Daily temperatures in a catchment in Bergville, KwaZulu Natal were measured in station

A$,$ Station B$,$ Station C$,$ Station D and Station E as $4C,15C,-2C,10C$ and $-3C$

respectively. Based on the mentioned statement Answer the questions below:

$2\mathrm{.}1$ Calculate mean daily temperature.

$2\mathrm{.}2$ Calculate true average temperature.

$2\mathrm{.}3$ State $(5)$ parameters that would be involved in determining natural evaporation in

the catchment area.

$2\mathrm{.}4$ Discuss how these parameters in $2\mathrm{.}3$ influence the evaporation in the catchment?

A civil engineering project involves the design of a water supply system for a

catchment area. The catchment area has an average annual rainfall of $1200mm$ and

an area of $500$ hectares. The evapotranspiration rate is estimated to be $800mm$

annually. Calculate the following:

$3\mathrm{.}1$ Total Precipitation over the catchment area in cubic meters.

$3\mathrm{.}2$ Total evapotranspiration from the catchment area in cubic meters.
