Help? Which of the following is caused by the urban heat island effect? A. decreased greenhouse gas emissions
B. cooler stormwater runoff
C. increased energy use
D. decreased energy use

The main cause of the urban heat island effect is from the modification of land surfaces. ... Monthly rainfall is greater downwind of cities, partially due to the UHI. Increases in heat within urban centers increases the length of growing seasons and decreases the occurrence of weak tornadoes. Because the heat is trapped on lower levels, the temperature is warmer. Urban heat islands can have worse air and water quality than their rural neighbors. UHIs often have lower air quality because there are more pollutants (waste products from vehicles, industry, and people) being pumped into the air.

Explanation:

What is the Urban Heat Island Effect? ... Communities by increasing summertime peak energy demand, air conditioning costs, air pollution and greenhouse gas emissions, heat-related illness and mortality, and water quality.

ask your friends for what they got then copy it down if you don't have any friends which is fine than google it or pay the teacher
