A student researching cities has taken notes:
• Cities are heat islands due to concrete and lack of vegetation • Heat waves are becoming more frequent and deadly • Green roofs can significantly lower building temperatures • Tree canopy provides natural cooling • Cool pavements reflect rather than absorb heat
The student wants to explain solutions for urban heat.
Heat waves in cities are becoming more frequent and deadly.
Cities can combat heat through green roofs that cool buildings, tree canopy for natural shade, and cool pavements that reflect rather than absorb heat.
Cities become heat islands due to concrete and limited vegetation.
Cool pavements reflect heat rather than absorbing it.
Correct Answer: B
Choice B. Green roofs, trees, and cool pavements are specific solutions.
