Explanation:

An urban heat island, abbreviated UHI, is used to describe urban areas or typical cities or metropolitan areas which are warmer than surrounding areas such as the rural areas.

UHIs are common among large commercial cities which are high populated.

Answer 2

Answer:An urban heat island

Explanation:An urban heat island refers to when a city becomes much warmer especially at night more than nearby rural areas. This difference is a result of how surfaces in each place absorb and hold heat.

Why does this happen?

A rural area is on the country side while an urban area is ina city , these places experiences the heat from the sun in the same way but the way they absorb and hold heat is different.

Rural areas are covers with plants ,grass and farmland which has green crops. All these plants absorb water and some water during the process of transpiration moves to the stem and leaves , this water on the leaves get evaporated and is released into the air. This is the same water that will cool out the nature in rural areas.

On the other side if you go to the city there no plants but many tall buildings ,streets and parking lots all of these are usually all dark materials.

Dark materials absorbs all wavelength of light and covert it into heat , which warms up the area
