The Earth doesn't revolve at the same speed. It is constantly slowing down, although at a very very slow rate. Also, the sun never rises or sets.

the earth makes a rotation every 24 hours which is where the time comes in for the sun to rise and to set- which is actually the part of the 24 hour rotation. A revolution takes 365 days which is where the seasons come in line.

It takes about 365 days for the earth to revolve around the sun.
It only takes 24 hours for it to spin on its own axis.
SOoooo.. earths revolution (or orbit) around the sun has nothing to do with the sun rising or setting.

The sun doesn't rise or set. As you just said, it's the earth that revolves.

Common sense, it could only rise and set at the speed of the earth, all else is just an optical illusion.

you are asking why the sun appears to accelerate when it is closest to the horizon...yes? this is actually an 2 things, the 1st of which is the existence of the horizon creates an optical illusion that make it look like it is going faster. if you were to have something like a sky scrapper you would see the same relative effect. the concept is the same as when you are at the airport and see a plane taking off, it appears to be going very fast as it is closer to you and there are stationary objects (like the sun and horizon) for a point of reference, and when it is flying at altitude it looks to be going slower...in reality they are going much faster at altitude.
the 2nd is the physics of the light refracting through more atmosphere in getting to your eye, but that is a very small percentage of your answer.

the earth is spining at 1000 mphr to the east light thravels at 186000 mphr the sun set you see is actaly 8 mins past the sun is past the horriison.8mins ago. the sun is stationary and the earth and allother planets spin around it at great distance I hope this helps you understand it all better.

because it's on it's axis in the winter it's dark a lot in the summer it's light a lot

it doesn't, it's just that we're buzzing around and not keep track of time and by the time we do, it's sunset.

It doesn't. It just looks that way.
