Moment of sunrise is captured in this beautiful dreamy and pastel toned image that shows the ocean in movement. There is some rocks on the background. Sunrise or sunup is the moment when the upper rim of the Sun appears on the horizon in the morning. The term can also refer to the entire process of the solar disk crossing the horizon and its accompanying atmospheric effects. Although the Sun appears to "rise" from the horizon, it is actually the Earth's motion that causes the Sun to appear. The illusion of a moving Sun results from Earth observers being in a rotating reference frame this apparent motion caused many cultures to have mythologies and religions built around the geocentric model, which prevailed until astronomer Nicolaus Copernicus formulated his heliocentric model in the 16th century. At sunrise and sunset, when the path of the sunlight through the atmosphere to the eye is longest, the blue and green components are removed almost completely, leaving the longer wavelength orange, red and pink light. The remaining pinkish sunlight can also be scattered by cloud droplets and other relatively large particles, which give the sky above the horizon a pink or reddish glow.
