Geochemistry Question:
Do you know what makes mountains appear purple?
Answer:
This is to do with light and the atmosphere.
The way the rays of light strike the mountains at a greater height than us, then reflect and reach our eyes below the height of mountains, coupled with the air in-between, leads to them looking purple, in a similar way to the process with different wavelength light makes the sky look blue on a sunny day.
