When the completes a full rotation, it is called a revolution. The Earth rotates at a speed of 1,000 mph, taking 24 hours to complete a revolution.
A planet completing one full rotation on its axis is called a "day." This is what determines the length of a day on that planet.
yes
There is no such line. The imaginary line through its centre is the axis, which the Earth rotates around; the imaginary line an equal distance from the poles is the equator. Neither make it spin - that is caused by momentum from the planet's formation.
Mars takes about 24.6 hours to complete one full rotation on its axis, which is slightly longer than an Earth day.
it takes 24 hours for the earth to spin all the way around.
one rotation is one day.
A planet completing one full rotation on its axis is called a "day." This is what determines the length of a day on that planet.
rotationis one complete spin on earths axis!!!
360 Edit: There are a few ways of asking this. Once around the Sun? Once around its axis? From full Moon to full Moon? From noon to noon? Each has a different value. Assuming you mean one revolution around its axis then just about 23 hours, 56 minutes. 4.09 minutes.
On its axis Earth rotates around the sun.
24 hours = 1day for it to spin around once on its axis
Rotation

Yes
It takes Mercury about 59 Earth days to complete one full rotation on its axis. This means that a day on Mercury (one full rotation) is equivalent to 59 Earth days.
24 hours
Earth takes one full spin around its axis in a day. The Circadian Rhythm occurs in one day.
