The Heat Island Effect refers to the phenomenon where urban areas experience higher temperatures than their rural surroundings. This occurs due to human activities, such as the use of concrete and asphalt, which absorb and retain heat. Additionally, buildings and vehicles generate heat, further increasing local temperatures. Factors contributing to the Heat Island Effect include reduced vegetation, which normally cools the air through shade and evapotranspiration. Urban planning and design can mitigate this effect by incorporating green spaces, reflective materials, and energy-efficient practices, helping to create a more sustainable environment in cities.
