Detailed Solution

The above statement is True.
When light passes through the atmosphere, it is first absorbed by air molecules, dust particles, smoke, and small water droplets and then re-emitted in various directions. The term for this occurrence is "light scattering." The sky over big cities looks less blue than the other parts, this is due to the reason that the air pollution in the cities causes the presence of large size particles in the air. These particles can scatter the lights of other particles too. Hence, the sky appears less blue.
