Urban Forestry & Heat Islands
EXAMINATION SET 2026 SOLVED
QUESTIONS GRADED A+
● what areas are cooler? Answer: rural and suburban areas are cooler
during day and night because they have less cement and are less dense
● how do heat islands form? Answer: urbanization
permeable/moist surfaces become impermeable/dry
● what are the benefits of heat island areas? Answer: lengthening plant
growing season
● what are the detriments of heat island areas? Answer: increased
energy consumption, elevated emissions of air pollutants and greenhouse
gases, compromised human health/comfort, impaired water quality
● how can the urban heat island effect be reduced? Answer: increased
vegetation, create rooftop gardens, install cool/reflective roofs, use cool
pavements
● what is the temperature variance between green roofs and traditional
roofs? Answer: 90 degrees
