The rotation causes the days, 24 hour periods of light and dark based on your location on the Earth. The rotation is important because without rotation of the earth, we would not as easily be able to tell, or keep track of time. What we consider to be the passage of time- 1 minute, 1 hour, 1 day, is all relative to how fast the Earth is rotating. Now as the Earth is rotating, it also is at a very specific tilt. The Earth is at a tilt of 23.5 degrees, meaning when it is rotating around the sun it isn't straight "up and down". The tilting is important because it gives us seasonal variation. The tilt is what causes the seasons to change. Which is important to humans, because it dictates climate in certain areas, growing seasons in agriculture, climate for survival for many animal species, and so on.
It takes 24 hours to turn its axis.
Yes, Earth does spin on its own axis. The axis is on a tilt of 23.5 degrees by memory.
Continuously, at all times.
because the earth is on an axis.
No , it takes 59 Earth days for Mercury for one rotation on its axis.

The earth revolvs on its axis. 1 complete turn takes 24 hours
One. Well, not QUITE one, to be exact. It takes 23 hours 56 minutes for the Earth to turn precisely once on its axis.
Half a day, obviously.
