Questions – Geography Grade 12: the difference between rural and urban climates
The climatic element illustrated in the sketch is (wind/temperature)
Answer: Temperature
Explain how the different shapes and density of buildings (in the sketch) contribute to the city having higher temperatures
Answer:
- Tall buildings cause the sun’s rays to be reflected and deflected between the buildings
- Large surface areas of buildings absorb more of the sun’s rays
- Density of buildings ensures that the heat remains closer to the earth’s surface
In a paragraph of approximately EIGHT lines, explain how urban planners could put strategies in place regarding the shapes and density of buildings in order to reduce the higher temperatures
Answer:
- Paint buildings in lighter colours e.g. white to increase reflection of heat
- Planting gardens on roof tops will cool temperatures
- Buildings should be eco-friendly (green)
- Future land use planning (buildings) should coincide with prevailing wind directions to cool cities
- Decentralise commercial activities to reduce building density
- Decrease building height to reduce heat trapped by buildings
- Decrease building density to reduce heat near surface
- Filters in chimneys of buildings to reduce air pollution
