Answer
The general trend of the change in temperature from P to Q is increasing. This indicates that as one moves from spot P (block I6) to technical college Q (block I10), the temperature rises throughout the day.
Step 2
Give a reason from the topographic map to explain the difference in temperature at P and Q.

Answer
The difference in temperature between points P and Q can be attributed to the altitudinal variation and land cover. Point Q is likely to have structures such as buildings that absorb heat, whereas area P may be at a higher altitude or have more vegetative cover, resulting in cooler temperatures.
Step 3
Identify and explain ONE strategy that could be implemented by the local municipality in block I10.

Answer
Identification: Green belts/vegetation areas.
Explanation: Implementing green belts or areas with vegetation can help maintain cooler temperatures. Vegetation absorbs greenhouse gases and provides shade, lowering the overall temperature in urban settings, thus mitigating the heat island effect in block I10.
