If you move the pencil along the top circle (which, if I recall correctly, is called a parallel), the pencil is moving along the north-south direction. If instead, you stop all north-south movement, and instead move it out/in and up/down, you're moving it along the east-west direction. (The circle created by this movement is a meridian, by the way. I'm not sure what you mean by "crossing the meridian", since I recall nothing special about crossing meridians.)

The best thing to do it to draw them out on a paper and draw each step, you can't really picture it any other way(unless your some kind of genius).
