londirtude is lond and latitude is fat
Lines of longitude all run North/South and are all the same length.
latitude 15degrees south longitude 47degrees west
it is located on the 0 degree longitude line
It is an undebatable statement of simple fact, where longitude is concerned.
Taken together, that pair of numbers is unusual because no other city ...in fact no other point on Earth ... has the same latitude and longitude.
One obvious error is the fact that any "east" number is a longitude, and any "south" number is a latitude.
The meridian of 15° East longitude crosses territory on the continent of Europe, Africa, and Antarctica.
Meridians of longitude join the north and south pole and are all about 12,400 miles long.
Yes, it does. In fact, the Prime Meridian - the zero mark for longitude - is defined as the logitude of the Royal Observatory in Greenwich, England.
