I'm always forgetting, which ones are the lines parallel to the equator (horizontal) and which are the ones that go vertically and all cross at the poles?
Think: If you traced a line of longitude (they go around the earth and converge at the poles) as a line, every single one of those lines would have the same LONG length, but, if you trace out any latitude (parallel to the equator) as a line, they would all shorter (different lengths in fact) than the one that goes around the equator itself.

TO REMEMBER: latitude line are flat on the globe so: lat-flat
Longitude lines are up and down so: long-is up and down

Longitude=always long
Latitude=not always long
Latitudes are parallel to the equator. They go from 90degrees S to 90degrees N
Longitudes go through the north and south poles.
Its 0 degree is at the Prime meridian in Greenwich.
Latitude = Equator and other parallels.
Longitude = Meridians and are great circles passing through the poles
