Worked Solution & Example Answer:Find Bowkerskop in the south-eastern section of the orthophoto map - NSC Geography - Question 3 - 2016 - Paper 2
Step 1
3.1.1 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. This refers to the direction that a slope faces in relation to the sun's rays, which affects the amount of sunlight received, moisture retention, and ultimately vegetation growth.
Step 2
3.1.2 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 at Bowkerskop receive more sunlight during the day, leading to higher evaporation rates and drier soil conditions, which results in lower vegetation density. Conversely, south-facing slopes are shaded and retain more moisture due to less direct sunlight, promoting greater vegetation density.
