The main cause of the urban heat island effect is from the modification of land surfaces. Waste heat generated by energy usage is a secondary contributor. As a population center grows, it tends to expand its area and increase its average temperature.
What are the 4 major impacts of urban heat islands?
Heat islands contribute to higher daytime temperatures, reduced nighttime cooling, and higher air-pollution levels. These, in turn, contribute to heat-related deaths and heat-related illnesses such as general discomfort, respiratory difficulties, heat cramps, heat exhaustion, and non-fatal heat stroke.
What causes urban heat islands quizlet?

What causes the urban heat island effect How can this effect be mitigated?
Green Roofs and Vegetation Cover Plants on the roof are excellent insulators during summer and decrease the overall urban heat island effect. Plants also cool the surrounding environments, thereby reducing air conditioning demands.

What is urban heat island in geography?
An urban heat island, or UHI, is a metropolitan area that's a lot warmer than the rural areas surrounding it. Heat is created by energy from all the people, cars, buses, and trains in big cities like New York, Paris, and London.
What is the urban heat island effect quizlet?
What is the Urban Heat Island Effect? A city or metropolitan area that is significantly warmer than its surrounding rural areas due to human activities.
How does urban heat island effect the climate?
It found that local warming, caused by the urban heat island effect, “significantly increases temperatures as well as economic losses in addition to global warming.” In fact, the study estimated that the added effects of urban heat island warming could double the economic losses expected from human-caused climate …
