Question

the urban heat island effect can be caused by impervious surfaces (like concrete) and air conditioning units. which of these also causes the urban heat island effect? increased vegetation fuel combustion

Explanation:

The urban heat island effect is caused by factors that generate or trap heat. Impervious surfaces (like concrete) absorb and retain heat, and air - conditioning units release heat. Fuel combustion (e.g., in vehicles, power plants) also generates a significant amount of heat. Increased vegetation, on the other hand, has a cooling effect through processes like evapotranspiration.

Answer:

Fuel combustion
