  2. Atmospheric optics - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_optics

    This process of reflection/absorption is what causes the range of cloud color from white to black. [19] Other colors occur naturally in clouds. Bluish-grey is the result of light scattering within the cloud. In the visible spectrum, blue and green are at the short end of light's visible wavelengths, while red and yellow are at the long end. [20]

    Red is also created by oxygen but in the highest part of the atmosphere at more than 150 miles above the Earth's surface. Purple and blue are related to nitrogen, with purple lights appearing ...

  4. Earth's atmosphere scatters shorter wavelengths of light, particularly blues and violets, more than longer wavelengths like reds and yellows, and this scattering is why the Sun appears yellow during the day or orange or red during sunrise and sunset. The scattered blue/violet light, appearing to come from all directions, is what makes the rest ...

    [28] [42] Lockwood and Fröhlich, 2007, found "considerable evidence for solar influence on the Earth's pre-industrial climate and the Sun may well have been a factor in post-industrial climate change in the first half of the last century", but that "over the past 20 years, all the trends in the Sun that could have had an influence on the Earth ...

  8. Soil color - Wikipedia

    en.wikipedia.org/wiki/Soil_color

    Highly oxidized red soil in Tirunelveli District, India. Red colors often indicate iron accumulation or oxidation in oxygen-rich, well-aerated soils. [4] Iron concentrations caused by redox reactions because of diffusion of iron in crystalline and metermorphic rock, in periodically saturated soils may also present red colors, particularly along root channels or pores.

  9. Cloud iridescence - Wikipedia

    en.wikipedia.org/wiki/Cloud_iridescence

    Larger ice crystals do not produce iridescence, but can cause halos, a different phenomenon. [9] Irisation is caused by very uniform water droplets diffracting light (within 10 degrees from the Sun) and by first order interference effects [10] (beyond about 10 degrees from the Sun). It can extend up to 40 degrees from the Sun. [11]
