Question

Which of the following are the reasons why cities are hotter compared to villages?

• A. There are fewer trees in cities.
• B. Building and roads absorb heat.
• C. Presence of a large number of automobiles.
• D. None of the above

Answer 1

Answer: (A), (B), (C)

Presence of a large number of automobiles.

As a city develops, roads are paved with asphalt, more buildings made up of metals and concrete come up and vegetation is cleared. Materials such as asphalt, concrete and metals absorb a lot of heat from the atmosphere while high rise buildings break the flow of the air. All of these factors collectively lead to heating up of the cities.
