A mixture of particle sizes
Mars' atmosphere always contains a lot of dust, and its sky is a Martian sky that is generally butterscotch in color, except for the pink or red of sunset.
Generally these are made by aeroplanes. The local pressure differences caused by the plane's wings may cause air moisture to condense into fog (or cloud) as they pass through it. These streaks are known as vapour trails.
A wide space, an atmosphere, as seen from the surface of the Earth that contains a layer of gases which are held in place by Earth's gravity.
The blue of Earth's sky is caused by sunlight scattered in the atmosphere. When you get above the atmosphere, the sky turns black. The Moon has no atmosphere at all, and so the sky looks black at any altitude.
If there were no atmosphere at all, the sky would be black. If there were some other kind of atmosphere, the sky would be colored according to the make-up of the atmosphere.
the atmosphere...??
Evidence of atmosphere on Earth includes the presence of gases like oxygen and nitrogen, the ability of sound to travel through air, the existence of weather patterns like rain and wind, and the blue appearance of the sky due to scattering of sunlight by air molecules. Earth's atmosphere also protects life on the planet by absorbing harmful solar radiation.
Technically you could, but most people refer to the sky as our atmosphere... past our "sky" is space. On the contrary, many people look at the stars and say "look at the beautiful sky," but the sky is generally referred to as our atmosphere.
the sky is so big because it is called the atmosphere.
the colour of sky from the moon is blak as there is no atmosphere .
