in QUESTION 2.1.4 above. Substantiate the above statement by calculating the average gradient along line T on the map from a contour line with a value of 1160 m to the contour line with a value of 1140 m.

Gradient =HEVI

VI = 1160 m – 1140 m = 20 m

HE =2cm1

2.1.6 Using the orthophoto and the topographic map, calculate the total

distance (in km) which a taxi travels to convey the passengers from point 20 in Dundee to Vryheid. Photo distance = 18,9 cm x 10 000 cm 100 000 cm = 18,9 cm 10 = 1,89 km + 75 km = 76,89 = 77 km (Range = 76,75 - 77) (5 x 1) (5)

(MEMO 06/09) GEOGRAPHY – SECOND PAPER (GEOG) 7 2.1.7 You are a land surveyor who is working at a second road

construction site at R. Your manager wants to inspect the first site at S that you worked on earlier. In order for your manager to use this map, she needs the magnetic declination for 2009.

(a) Determine the magnetic declination for 2009.

Difference in years = 2009 – 1981 = 28 years Change = 2’ x 28' = 56' W √ Declination in 2009 is = 18º07' ± √ 56' 18º63' = 19º03' W √ (4 x 1) (4)

(b) Provide the manager with the exact magnetic bearing if the

true bearing is 106°, in order for her to use her compass. MB = MD + TB = 19°3’ + 106° = 125°03’ (1 x 2) (2)

QUESTION 3: MAP INTERPRETATION AND ANALYSIS 3.1 Refer to landforms L in block I8 and K in block J10 and answer the

following questions: 3.1.1 Name the landforms labelled K and L on the topomap.

K = Pointed butte L = Mesa / Table mountain (2 x 2) (4)

3.1.2 What is the difference in height between landforms K and L,

if the height of K is 1781,2 metres? 1781,2 – 1639,9 = 141,3 (1 x 2) (2)

3.1.3 Explain why the landforms K and L maintained their original

height despite the areas exposure to erosion. The hard cap rock are resistant to erosion (1 x 2) (2)
