Question

heat islands and effectsboundary layer heat islands start at rooftops and extend vertically up to a mile above the city, forming a vertical heat island.what are urban heat islands caused by?increased vegetationincreased heat-absorbing surfacesfrequent rainfalllow population density

Explanation:

Urban heat islands form because human-made surfaces like asphalt and concrete absorb and retain far more heat than natural, vegetated surfaces. Increased vegetation, frequent rainfall, and low population density would reduce, not cause, urban heat island effects.

Answer:

B. increased heat-absorbing surfaces
