Cloudy Sky Wallpapers for Android

The sky, also known as the celestial dome, commonly refers to everything that lies a certain distance above the surface of Earth, including the atmosphere and the rest of outer space. In the field of astronomy, it is also called the celestial sphere. This is an imaginary dome where the sun, stars, planets, and the moon are seen to be traveling. The celestial sphere is divided into regions called constellations. Usually, the term is used from the point of view of the Earth's surface. However, the exact meaning of the term can vary; in some cases, it is defined as only the denser portions of the atmosphere, for example.The blue color of it results from the selective scattering of light rays by the minute particles of dust and vapor in the earth's atmosphere. The rays with longer wavelengths (the reds and yellows) pass through most readily, whereas the shorter rays (the blues) are scattered. An excess of dust, especially in large particles, causes scattering of many rays besides the blue, and the sky "fades" and becomes whitish or hazy. It thus is clearest in winter, in the morning, after a rain, over a mountain, or over the ocean.Pictures of cloudy sky can be really enjoyable and relaxing. Use the chance to set one of them as your new ideal phone wallpaper.
