Why can abundant atmospheric dust make sunrise and sunset more colourful?
Answer and explanation
Correct answer: Because they increase scattering of light
Sunlight contains many wavelengths. When the Sun is low at sunrise or sunset, its light travels through a longer atmospheric path, and dust and aerosol particles can scatter and absorb some wavelengths more strongly than others. This changes the balance of colours reaching the observer, often enhancing red, orange, or pink tones under suitable conditions. Thus A is correct; dust does not change oxygen or nitrogen into luminous or coloured substances, and it does not solidify ozone.
