why sky looks blue in day and black in night
Answers
Answer:
The daytime sky is blue because light from the nearby Sun hits molecules in the Earth's atmosphere and scatters off in all directions. The blue color of the sky is a result of this scattering process. At night, when that part of Earth is facing away from the Sun, space looks black because there is no nearby bright source of light, like the Sun, to be scattered. If you were on the Moon, which has no atmosphere, the sky would be black both night and day. You can see this in photographs taken during the Apollo Moon landings.

please mark my answer as brainliest
Answer:
During the day (daylight) the sky has a blue appearance because the Sun`s light (white light) is made up of rainbow of colors (red, orange, yellow, green, blue, indigo and violet) of different wavelength. ... The black sky at night that shows you the moon, planets and stars is due to the absence of the Sun`s light.
