Because you're only looking at 1/4 of the globe, or at a map of only part of the Earth.
Go far enough north from where you're looking, and you're sure to find latitude lines
that are labeled ' N '.
Go far enough either east or west from where you're looking, and you're sure to find
longitude lines that are labeled ' W '.
They're not ! If that's what you see on your map, then your map only shows part of the Earth ... it could be some parts of Africa, the Indian Ocean, Antarctica, or Australia. If you look at a globe or a map of the whole Earth, you'll see that half of all the latitudes are North and the other half are South. Also, half of all the longitudes are East and the other half are West.

All lines of longitude meet at the North and South Poles.
All the lines of longitude meet or converge at the North Pole - they meet at the South Pole too!
All 'lines' of latitude are parallel to all others.No meridian of longitude is parallel to any others.-- All 'lines' of latitude are parallel to all others.-- No meridian of longitude is parallel to any other one.
All the lines of longitude.
All lines of longitude are equal. The longest line of latitude is the Equator.
All lines of longitude pass through the Equator.
Meridians of Longitude All of the other meridians; the lines of longitude.
All meridians of longitude converge at the north and south poles.
Every 'line' of constant longitude is a 'meridian'.
Lines of longitude are imaginary vertical lines that represent the angular distance, in degrees, minutes, and seconds, of a point east or west of the Prime Meridian (Greenwich). Lines of longitude are often referred to as meridians. The lines of longitude run from the North pole to the South pole and at the poles all the lines of longitude intersect at a single point.
