Sun on Horizon
My recent interest is in photographing Sunrises and Sunsets. When reviewing some of those pictures, I came across a very peculiar one. The Sun was on the horizon, but I (almost) could not tell, whether it was taken during Sunrise or Sunset. This got me thinking. Sunrise and Sunset are terms given by us, but are they really different, the fact is, Earth rotation cause this.
By looking at a picture of a Sun on horizon, can you tell whether its taken at Sunrise or Sunset ?

One will be over land and one over sea, unless of course you are on an island. The question really becomes where is it taken.
Time stamp on the photo ?
Should there be trees within the photograph one could determine which side the moss is growing on and with it determine the general directions of NSEW and then compare with the sun...if in the West sunset, East sunrise.
At sunrise the air is cleaner, with less pollution the sky appears mostly blue with little orange and yellow. at sunset their is more pollution in the air because most of our activity is during the day, with more pollution the sky appears mostly yellow, orange, and purple

if the sun in the picture is small it was taken in the morning if at sunset then it would be bigger maybe?
Heat waves from the ground will cause a setting sun to shimmer. The ground is cool during sunrise and will not show the shimmer..
There is in difference in a picture as our sunset is someone elses sunrise somewhere and vice versa!
and one side of the sun does not look different than the other.
The sky is brighter at sunset than it is at sunrise. the sky is still dark when the sun is rising but it is still light when the sun is setting.
I know exactly how to tell!!!
Just look at the time it was published. DUH!!
The idea of getting the answer from trees in the picture won't work, as the idea of moss growing on the north side of trees is a myth. I'd say your best bet is to look at the coloration of the sky, as said above.
Of course, you didn't say whether it was cloudy or clear at the time. Clouds might conceal a lot of hints that atmospheric coloration would otherwise give you.
rise and set are in east and west.
The Sun is neither Rising nor Setting. ;)
Unfortunately, we usually can't tell which way is east and west in a photo, but I was taught (like some of the others above) that sunset is darker because more dust and other junk is kicked up into the air (as opposed to sunrise where not too much has happened yet in the day.
As an amateur astronomer, I've posed this question to others as well and I feel that the best way to tell whether it is a sunrise or sunset is to look at the air.
If the sun is setting, the air and the ground have already been heated throughout the day and the air near the ground will create a shimmer effect. Therefore, if you are looking at a sunset/sunrise picture and the sun looks a little bit blurry or ripply, then it is likely a sunset.
However, as the sun rises to mark a new day, the air and the ground have been cooling overnight, this creates very still, clear air. A sunrise will almost always look very sharp and distinct.
However, many factors do come into play during sunrise/sunset so these things can never be counted on as a correct indication of whether it is a sunset/sunrise.
Sunrise is usally more pink and red, while sunset is more yellow but up here in the north when it's light all summer and get very little light in the winter you don't see very many sunrises or sunsets
no because sunset in one place is sunrise at another place
so sunrise is sunset
Where can one find the answers to these questions?
Its SYMPLE you look at the sky if its dark its night if its light its day!!!!!!!!!!!
simply look at the activities of everything around in the photo lol
The author states that there was only one "peculiar" photo, and the reason for it being described as “peculiar” was due specifically to the difficulty had in distinguishing it from a sunrise or a sunset. The author also states that He/She "almost" could not tell which one it was. An answer of "You cannot tell the difference..", should be ruled out since the author finds it strange to even have a little difficulty differentiating between the two. This would also lead me to believe that the answer will not rely on studying objects other than the sunrise itself, since there may or may not be in any given photo, other objects at all, let alone something that would reveal an absolute answer so often as to b e peculiar when it does not. So what is the answer? I don’t know, but I am betting that it has to do with the Sunset/rise itself as opposed to being a trick question.
Look at the SIZE of the sun!
it would be both as it will be both sunrise and sunset somewhere in the world
Yes but if you're standing outdoors looking at a sunset, are you going to say "That's a fine sunrise right there."?
Neither.
in a sense, the sun dosn't really rise or set, actually, it's barely moving in orbit.
BUT the earth is turning which causes "sunset" or "sunrise".
I love how people twist the question to make themselves seem witty.
HEY!!!!............eh, u may be right...
Lets say the photo is taken in the summer in a heavily populated area. In the summer the sun rises pretty early, so not many people would be out. Depending on how many/few people are out will dictate weather its a sun set or rise.
ANSWER
------------
There can be many more reasonable explaination but this is the closest.
The atmosphere is different due to the presence of sun whole day (12 hours) and absence of Sun whole night. so even the sun set and sunrise are just the position of the sun at east and west there is difference in color of the picture due to atmospheric heat and lack of heat.
GOT RIGHT
