Answer: 2 marks: 1 mark for isohyets, 1 mark for isotherm.
It will be visual judgement for quite generalised lines but half marks may be awarded for lines that approximate to the actual lines.
For the isolines the areas have to:
- ‘Move’ towards the right direction,
- Follow some topography (hills, mountains, river valleys),
- Have an isohyet in south-western part of the country,
- Separate isohyets for Darfur region,
- Excellent if student could consider the uneven time periods:
NB! 1960–1989 is 29 years
