1. Define “Urban heat island”:
Urban Heat island is when buildings, roads,and other infrastructure replace land and vegetation and make it impermeable and dry these changes make an area to be warmer forming a hot island
2. Sketch the temperature variations as shown on the website onto the profile below. Discuss which areas are cooler
During the night rural areas are cooler because there is less things there to absorb heat also there is more trees their to block the heat of the sun
During the day ponds are more cooler

3. How do heat islands form? Describe 2 methods that contribute to higher urban temperatures from heat islands.
They form when the infrastructure of the city changes the vegetation of the land. 2 methods are having less dense areas so it traps more heat also being away from a body of water which makes place cooler
Why Do We Care About Heat Islands?
4. Discuss the environmental benefits/detriments of wintertime and summertime heat island areas.
The detriments of the summertime is that more people use air conditioner and use to much electricity and the benefit in the winter time is that there is no need for an air conditioner
5. What are some of the things that can be done to reduce the urban heat island effect?
Stop using so much electricity because power plants which make the electricity release greenhouse gasses and air pollutants
6. What is the temperature variance in green roof vs. traditional roof?
Green roofs provide shade and make a place cooler and a traditional roof traps heat and gives no shade
7. Describe some benefits of green roofs:
They provide shade
Make a house/building cooler
Heat Island Impacts
8. What are the 4 major impacts of urban heat islands?
- Increased energy consumption
- Elevated emissions of air pollutants and greenhouse gasses
- Compromised human health and comfort
- Impaired water quality
9. Name 2 human health effects of heat islands
To much hotness can be a risk to some population like children, also air pollution cause health problems in the lungs
Urban Heat Island Mitigation
10. What is a cool pavement?
It is a type of pavement that reflects solar energy increase water evaporation and make the pavement cooler
Where You Live
Click on California- list 2 things that are currently being done to help mitigate the effects of urban heat islands
1. In Los Angeles they are planning to plant one million trees
2. In San Diego they are planning to plant 5,000 shade trees
