Earth rotates on its axis once every 24 hours, so that objects on its surface execute uniform circular motion about the axis with a period of 24 hours. consider only the effect of this rotation on the person on the surface. (ignore earth's orbital motion about the sun.)

The effect of this rotation on the person on the surface is the sky is moving, like an apparent diurnal motion.

Explanation:

For an observer at a fixed position on Earth, the rotation of earth makes it appear as if the sky is revolving around the earth. In other words, if a person is standing for long enough in a field at night, it looks like the sky is moving, not the person. This motion is called "apparent diurnal motion."

Diurnal means having to do with a day, in a sense of a 24- hour period.
