Do Longitude lines crisscross at the North and South Poles?

Answer:

Technically, no. Longitudes all converge at the poles.

You might say to me: "The line if 80 degrees west longitude, for example, goes up to the north Pole.
It criss-crosses all the other longitudes there, and then keeps going down the other side."

But I would say to you: "No ! Fie ! A thousand times no ! While it may look like the line at 80 degrees west
goes through the pole and keeps going down the other side, that's actually not the same line on the other
side. Over there, that's the 100 degrees east line."

Every line of longitude is a semi-circle that fits neatly between the poles. They all converge at the poles,
but they all start/stop there, and they never cross.

Why do the north and south poles have no longitude lines?
Technically, the north and south poles both have all possible longitudes. The meridians or "lines" of longitude all meet at the poles. So, whatever longitude you're at, anywhere on earth, you can...
Why doesnt the North pole and the South pole does not have lines of longitude?
It would be incorrect to say that the North Pole and South Pole do not have lines of longitude. ALL lines of longitude pass through the North Pole and the South Pole.
Line from north to south pole?
Any meridian of longitude connects those two points, although it doesn't necessarilyproceed in either direction, i.e., you can't say where a meridian runs 'from' or 'to'.
Does lines of longitude get shorter as they approach north and south poles?
No
