Detailed explanation-1: -Cities might also have less reflectiveness, which would let them soak up more of the Sun’s heat. But most researchers have considered the biggest contributor to the urban heat island effect to be the reduction in evaporation that occurs when plants are replaced by concrete.
Detailed explanation-2: -In cities, we find high rise buildings. The concrete and metals in these buildings and the asphalt of roads get heated up during the day. This heat is released during the night. Another reason that the crowded high rise buildings of the cities trap the warm air and thus raise the temperature of cities.
Detailed explanation-3: -An urban heat island occurs when a city experiences much warmer temperatures than nearby rural areas. The difference in temperature between urban and less-developed rural areas has to do with how well the surfaces in each environment absorb and hold heat.
