Question 1 of 20
Urban heat islands form when roads, roofs and car parks absorb sunlight during the day and release it slowly at night. As a result, city centres can stay several degrees warmer than nearby rural areas well after sunset. Street trees help in two ways: their shade keeps surfaces cooler, and water evaporating from their leaves cools the air around them. However, trees need space for their roots and regular watering in their first years, which is why some councils have struggled to increase tree cover in older, densely built suburbs. According to the passage, what problem do some councils face?
