Answer:
Why is the sky blue?
As white light passes through our atmosphere, tiny air molecules cause it to 'scatter'. The scattering caused by these tiny air molecules (known as Rayleigh scattering) increases as the wavelength of light decreases. Therefore, blue light is scattered more than red light and the sky appears blue during the day.
Why does the moon appear in the daytime?
During the new moon, the moon is between the sun and the Earth, the side of the moon that is lit by the sun is facing away from our planet. This means that the moon is still up there, but we can’t see it in the daytime, because all of the sun’s light is getting reflected away from us. As the moon continues in its orbit around the Earth, away from the sun, increasingly more of its sunlit surface is visible. This is why the moon sometimes appears as a crescent or half-moon. When it’s farther from the sun and visible above the horizon, it’s easier to spot during the day.
How much does the sky weigh?
How much does air weigh? This means the sky weighs 14.7 lbs per square inch of earth surface which is roughly 11 billion billion pounds. So, you can say that sky weighs one millionth of the mass of the Earth.
How much does the Earth weigh?

Why does the moon appear in the day time?
We can see the moon during the day for the same reason we see the moon at night. The surface of the moon is reflecting the sun's light into our eyes. ... "When we see the moon during the day it's because the moon is in the right spot in the sky and it's reflecting enough light to be as bright, or brighter, than the sky.
