Question

Why can't we easily see stars and planets in the sky when we are in a city, but can see them clearly from elsewhere?

• A. City lights obstruct the light coming from stars and planets
• B. Because of the polluted air in the cities
• C. The statement is not true
• D. None of the above suits the explanation

Answer 1

The correct option is B

Because of the polluted air in the cities

Due to pollution, there are many particles in the air which absorb the light coming from the distant stars and planets. That is why stars visible in the cities are less in number, very faint and difficult to see.
