If I was in halifax at sunrise on the equinox and the earth stopped
rotating and I walked due east (towards the sun) across the ocean
I would end up in Southern Spain and not on my same latitude which is in
Southern France.
So I conclude that latitude lines are not east-west lines.
Correct?
thanks;

Hi Brent and all,
Compass directions that are pursued make spiral curves towards the
poles, if north of east-west then towards the north pole, if south of
east-west then towards the south pole. If east or west then they do
neither but continue east-west. Try Googling "loxodromic curve". It's
what you draw on a chart. Sailors call it a "rhumb line".

I'm confused maybe.
I live in the northern hemishpere and anticipating the equinox on the
23rd.
Supposedly the sun will rise due east.
So if due east is a right angle from north south and I traveled due
east I would not follow my line of latitude.
I would get further and further south of my latitude the further I
traveled.
So either the lines of latitude are not east west lines or due east
is not a straight line but curved.
I suspect lines of latitude are not east west lines?
They would work fine if the earth was not tilted, but it is.
Wouldn't it make sense to coordinate the globe so lines of latitude
(or call them something else) are straight and a right angle
from north south?
