Question

'Heat islands' are produced due to

• A. Air pollution
• B. Water pollution
• C. All of the above
• D. Land pollution

Answer 1

Answer: (A)

A heat island is an area that is constantly warmer than surrounding areas. One of the reasons for the formation of heat island is air pollution. Other important reasons are changes in landscape due to the construction of buildings, roads, and other infrastructure which had replaced open land and vegetation. An island formation is the result of local changes in the environment brought about by urbanisation and release of polluting gases.

So, the correct answer is option A.
