Primarily they see rotation and can see the earth pass beneath them. Revolving is usally referred to Earth going around the Sun. In time this can be seen visually using stars as a reference. But they cannot actually see the earth revolving as they would have to be extremely higher above the earth.

You are aware, I hope, that the space station orbits the Earth.

Therefore the Earth moves below them because they are passing over the terrain.

Since they go around it in little over an hour, and the Earth rotates in 24 hours, their motion is much more significant than the Earth's motion.

(some people seem to think satellites are stationary. Satellites have to orbit, otherwise they would not stay up there. Geo-stationary satellites orbit out there where their orbital period is 24 hours, the same as the rotation period of the Earth. Therefore they stay over the same point on the Earth even though they are orbiting. The space station is not one of these. )

Well, since the Earth moves so slowly, I imagine that the Earth doesn't appear to move at all, unless you stare at it for hours at a time, and only expect it to move a little way. I would think that if you picked a spot on Earth, and looked at that same spot the next day, it will be in a different postition, but like I said before it would take a lot of patience and eye strain to actually "see" the Earth move.
