MEMORANDUM
GENERAL INFORMATION ON PIETERMARITZBURG
Pietermaritzburg (umGungundlovu) is the capital city of KwaZulu-Natal. This second largest city in the province was founded in 1838. It is a regionally important industrial hub, well-known for processing aluminium, timber and dairy products. It has an estimated population of around 500 000 (including neighbouring townships). Pietermaritzburg is situated along the N3 national road, the main route between the Pretoria-Witwatersrand-Vereeniging conurbation and the harbour city of Durban, some 90 kilometres from Pietermaritzburg. The Oribi airport is situated just outside Pietermaritzburg and has a regular scheduled service to the OR Tambo International Airport in Johannesburg.

The cold subsiding air cools the temperature to below freezing point ✓✓ [Any TWO] (2 x 2) (4)
3.2 Refer to slope 5 (low-income residential area) and slope 6 (high-income residential area) on the orthophoto map. 3.2.1 Explain how aspect of slope influenced the site of the high-income residential area at 6.
Slope 6 is a north/northeast facing slope and experiences the direct rays of the sun (making it warmer) ✓✓(1 x 2) (2)

[Any ONE] (1 x 2) (2) 3.2.3 Suggest how natural vegetation could have influenced the land values of residential areas 5 or 6.
The vegetation creates aesthetic appeal/beauty/scenery at 6 which increases the land value✓✓ OR
Lack of vegetation at 5 reduces the aesthetic appeal and decreases land values ✓✓
Vegetation creates cleaner (absorbing carbon) air this area attracts more residents and increases land values ✓✓
Vegetation lowers temperature on this north facing slope which is hot during summer ✓✓
[Any ONE. THE REASONS MUST REFER TO THE RELEVANT ESIDENTIAL AREA SELECTED] (1 x 2) (2) 3.3 Refer to Mabane River and the Gordon Falls in block H2 on the topographic map. Directly upstream of the Gordon Falls the river meanders and directly downstream of Gordon Falls, the river follows a straight path. Explain the reasons for the difference in the stream channel patterns of the Mabane River, as mentioned above.
Upstream of the Gordon Falls the wider space between the contour lines shows the river flows on level ground/slower velocity (speed) making it meander ✓✓ OR
Upstream of the Gordon Falls the landscape is flatter/slower velocity (speed) which allows the river to meander ✓✓
As the water flows over the waterfall it becomes more energetic, due to a steeper gradient/higher velocity (speed) resulting in a straight course downstream of the Gordon Falls ✓✓ OR
Rejuvenation downstream of the Gordon Falls result in vertical erosion therefore a narrower river valley results in a straightened pattern ✓✓ (2 x 2) (4)
