What it does everyday... MOVE!
the earth spins once on its axis during the time we call a day
The rotation of the earth is what gives motion to the heavens.
Rotation
The moon doesn't actually move across the sky during the day. It is the rotation of the Earth that makes it appear this way. The moon's orbital motion around the Earth causes it to be in different positions in the sky at different times of day.

Motion lights will work during the day, but won't be practical in daylight when everything is already well-lit.

The suns radiation heats up the earth during the day
Yes, the movement of Earth on its own axis is periodic motion. Earth completes one full rotation on its axis approximately every 24 hours, creating day and night cycles. This motion is predictable and repetitive, making it a form of periodic motion.
We call the Earth's daily motion "rotation", and its period ... about 24 hours ... a "day". We call the Earth's annual motion "revolution", and its period ... about 365 days ... a "year".
