Question

cities often experience higher temperatures because:
○ they contain dark surfaces that absorb heat
○ buildings block sunlight
○ they are closer to the sun
○ they have many surfaces with high albedo

Explanation:

Cities have the urban heat island effect. Dark surfaces like asphalt and dark rooftops absorb more solar radiation instead of reflecting it, which increases ambient temperatures. Blocking sunlight would lower temperatures, cities are not closer to the Sun than surrounding areas, and high albedo surfaces reflect heat (contrary to warming).

Answer:

A. They contain dark surfaces that absorb heat
