Answer:Cities with warmer temperatures than the natural environments that surround them are called urban heat islands. Man-made materials such as pavement warm up quickly during the day. These surfaces radiate heat, causing air temperatures around the city to rise. Even after the sun sets each day, the surfaces hold onto their heat, making it more difficult for the temperature in the city to decrease. Urban heat islands can have a negative impact on the environment and on the people residing in affected cities.This is harmful to the health of the people that live in the city. Increased electricity usage is also associated with urban heat islands because people need more air conditioning and cooling due to the higher temperatures. Solutions to the heat effect issue center around ideas that would reduce city temperatures, such as heat-reflecting roofs, more green spaces, and the use of cool-pavement materials.
