Detailed explanation-1: -Heat islands are urbanized areas that experience higher temperatures than outlying areas. Structures such as buildings, roads, and other infrastructure absorb and re-emit the sun’s heat more than natural landscapes such as forests and water bodies.

Detailed explanation-2: -In general, temperatures are different at the surface of the earth and in the atmospheric air, higher above the city. For this reason, there are two types of heat islands: surface heat islands and atmospheric heat islands.

Detailed explanation-3: -Tokyo, an example of an urban heat island. Normal temperatures of Tokyo go up higher than those of the surrounding area.

Detailed explanation-4: -Heat islands form as vegetation is replaced by asphalt and concrete for roads, buildings, and other structures necessary to accommodate growing populations. These surfaces absorb-rather than reflect-the sun’s heat, causing surface temperatures and overall ambient temperatures to rise.
