I'm doing my geography exam tommorow, and my revision guide keeps taliing about urban heat islands, what the hell are these?

On warm summer days, a city can be 6-8°F warmer than its surrounding areas. Scientists call these cities "Urban Heat Islands."

what, so the city center would be hotter than the suburbs, and the suburbs would be hotter than the countryside on warm summer days?

Why does it happen though?

Concrete reflects the heat of the sun whereas as earth and soil etc absorb it?

Only a guess on my part there.

Causes of the "heat island effect" include dark surfaces--that absorb more heat from the sun--and less vegetation that would provide shade and cool the air.

Also more people=more cars=more heating+lighting etc
