You may find that all mountains look blue from far away!Why is that？
Sunshine is a mix of red，orange，yellow，green，blue，indigo，and violet .Each color has a different length of wave （波長）.Blue has one of the shortest ones.
Earth's atmosphere （大氣層） is full of tiny air molecules （分子）.When light hits them，it gets scattered （散射） around.According to the website HowStuffWorks，light with shorter wavelength bounces like a ping-pong ball until it reaches our eyes.Blue light，which is about half the wavelength of red light，is scattered almost 10 times as strongly as red light.So blue is the main color of the atmosphere.
More distance from a mountain means more atmosphere.Finally，the mountain disappears into the sky as we only see blue light.The same thing happens with tall buildings，too.
