Urban Forestry & Heat Islands
PREPARATION TEST 2026 QUESTIONS AND
CORRECT ANSWERS 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
, ● what are the benefits of green roofs? Answer: reduced energy life,
reduced air pollution, improved human health/comfort, enhanced storm
water management and water quality, improved quality of life
● what are the 4 major impacts of urban heat islands? Answer:
increased energy consumption, elevated emissions of air pollutants and
greenhouse gases, compromised human health/comfort, impaired water
quality
● what are human health effects of heat islands? Answer: heat cramps,
exhaustion
● what is cool pavement? Answer: paving materials that reflect more
solar energy, enhance water evaporation, and remain cooler than
conventional pavements
● albedo Answer: - the reflectivity of a surface
- a ratio between isolation and amount reflected back into the
atmosphere
- lighter surfaces have a higher albedo
● urban greening Answer: planting trees and vegetation provides shade
and can have a natural cooling effect. Urban trees also act as carbon
