Earth is rotating ON an imaginary axis, not IN
one.
Imagine a ball with a long pole stuck through the
middle of it with the ends of the stick coming out of opposite sides of the ball. If you
held the ends of the stick in your hands and made it go around with your fingers, the
ball would turn at the same speed as the stick.
The stick
is the "axis" - the line around which the ball is rotating, moving in a circle around
that central line. The ball represents the Earth, rotating on its axis. There are no
real sticks coming out of the Earth to show where the axis is located because the axis
is imaginary, but the approximate locations where the "sticks" would be if they existed
are the North and South Poles.
