Urban City X has been referred to as an urban heat island because it tends to be warmer than the surrounding rural areas. The report below lists changes that have occurred in one year in Urban City X. Report for Urban City X: Eight roads were repaved. The population increased by 20%. Public transportation increased by 5%. Four new apartment complexes were built. Plans were drafted to build a local park. A meeting was held about alternative energy sources. What is the main cause of Urban City X being an urban heat island?

• the planting of trees and other vegetation

• the building of rooftop gardens
