What resource is most likely to contribute to heat island effect in urban areas?

• A. Natural vegetation
• B. Concrete and asphalt surfaces
• C. Ponds and lakes
• D. Forested areas

Answer: (B)

The heat island effect in urban areas is primarily caused by the absorption and retention of heat by surfaces that are commonly found in cities, such as concrete and asphalt. These materials have high thermal mass, meaning they absorb heat during the day and release it slowly at night, leading to elevated temperatures in urban locations compared to their rural counterparts. In contrast, natural vegetation, ponds, lakes, and forested areas tend to cool their surroundings through processes such as evapotranspiration. Vegetation and water bodies reflect more sunlight and facilitate heat dissipation, which mitigates the heat island effect. Therefore, urban environments with a high prevalence of concrete and asphalt are more likely to contribute to this phenomenon, intensifying local heat and affecting air quality and energy consumption.
