Worked Solution & Example Answer:Find Bowkerskop in the south-eastern section of the orthophoto map - NSC Geography - Question 3 - 2016 - Paper 2
Step 1
State, and define, the microclimatological phenomenon responsible for the difference in vegetation density on either side of Bowkerskop.
Answer
The microclimatological phenomenon responsible for the difference in vegetation density is known as slope aspect.
Definition: The location and direction of the valley/hill slopes in relation to the sun's rays.
Step 2
Explain how this microclimatological phenomenon in QUESTION 3.1.1 is responsible for the difference in vegetation density on either side of Bowkerskop.
Answer
North-facing slopes will experience more evaporation, leading to lower moisture content in the soil; therefore, vegetation density is lower.
Conversely, south-facing slopes, which are in the shadow of the koppie, will experience less evaporation, resulting in higher moisture content in the soil and thus a higher vegetation density.
