Which of the following is a benefit of a "green roof"?

A green roof offers several significant benefits, particularly in the context of urban environments. One of the prominent advantages is its ability to help manage stormwater. By incorporating vegetation and soil layers, green roofs absorb rainwater, which reduces runoff and minimizes the risk of flooding. This absorption also helps to filter pollutants and improve water quality before it enters drainage systems.

In addition to stormwater management, green roofs can contribute to enhanced energy efficiency by insulating buildings, thus reducing the demand for heating and cooling. They can also create habitats for various plant and animal species, supporting urban biodiversity. Moreover, green roofs can help combat the urban heat island effect, leading to cooler cities overall.
