Question

urban heat islands
effects of heat islands
heat island effect brings several consequences to cities. residents use air conditioning systems to combat the heat. this leads to increased energy use and pollutant release from power plants, worsening the heat island effect and creating a positive feedback loop
higher temperatures negatively impact human health and comfort, causing heat - related issues like heatstroke. when stormwater runoff from these areas can harm water quality nearby, especially when combined with pollution. heat islands are a form of thermal pollution.
green roofs, heat - reflective surfaces (such as paving, roofs, and greys), building features like overhangs, and vegetation all reduce heat, leading to decreased temperatures. these strategies help reduce the heat island effect, cut energy use, manage runoff, and moderate temperatures, creating a more sustainable and comfortable urban environment.
what term is used to describe a loop that amplifies the heat island effect?
stabilizing loop
cooling loop
negative feedback loop
positive feedback loop

Explanation:

Positive feedback loops amplify changes. In the context of urban heat islands, increased heat leads to more energy use (e.g., for air - conditioning), which releases more heat and pollutants, further increasing the heat island effect. A stabilizing loop would counteract change, a cooling loop is not a standard term in this context, and a negative feedback loop would reduce the effect (opposite of what's described).

Answer:

positive feedback loop
