Because the poles are points.

If you stick a pencil through the middle of an apple, you can grab the ends of

the pencil and spin the apple just exactly like the Earth spins. The pencil would

be the "axis" of the apple's rotation.

The Earth doesn't have a pencil sticking through it, but it spins just as if it did have,

and we can imagine the axis of the Earth's rotation. The points where the axis sticks

out of the Earth are the north and south poles. They're only points.

An egg weighs less than 1 kilogram - or an apple.

No, I have both and the charger on the pen doesn't fit into the phone charger.

If you want to spin an apple, it would be a lot easier if you stick a pencil through it

from top to bottom, and then spin the pencil. Notice that as the apple spins, the

pencil always points in the same direction and it doesn't move; it just sits there

and spins around the lead in the middle, while every part of the apple spins around

the pencil.

Even though there's no pencil stuck through it, the earth spins exactly the same way.

If you try hard though, you can imagine a pencil stuck through the Earth's north and

south poles. It's 8,000 miles long, it points at the North Star, and every part of the

earth spins around it.

The imaginary line through the earth, between the poles, right where you just

imagined that gigantic pencil, is called the earth's "axis". The word simply means:

"The line that everything else spins around".
