What is the urban heat island phenomenon?
What is the urban heat island phenomenon?
- The phenomenon of cities being colder at night than in the countryside.
- Heat absorbed by buildings and road surfaces during the day. (correct)
- The reflective power of materials covering building surfaces.
- The percentage gains in ground temperature due to white buildings.
How can cities utilize the albedo effect to combat high temperatures?
How can cities utilize the albedo effect to combat high temperatures?
- By promoting the use of high-reflecting paints on walls and roofs. (correct)
- By encouraging the creation of gardens with trees for shade.
- By abandoning asphalt and using porous surfaces for roads.
- By implementing more sprinkler systems on pavements.
What role do green roofs play in helping cities adapt to climate change?
What role do green roofs play in helping cities adapt to climate change?
- They prevent hot air from stagnating between buildings.
- They provide shade and maintain correct levels of evapotranspiration. (correct)
- They increase the ambient temperature through evaporation.
- They facilitate the seepage of water into the soil.
