Latitude Latitude In geography, latitude is a geographic coordinate that specifies the north–south position of a point on the Earth's surface. Latitude is an angle (defined below) which ranges from 0° at the Equator to 90° (North or South) at the poles. Lines of constant latitude, or "parallels", run east–west as circles parallel to the equator. Latitude is used together with longitude to specify the precise location of features on the surface of the Earth. On its own, the term latitude should be taken to be the "geodetic latitude" as defined below. Briefly, geodetic latitude at a point is the angle
Longest rivers of the United Kingdom Longest rivers of the United Kingdom This is a list of the longest rivers of the United Kingdom. There seems to be little consensus in published sources as to the lengths of rivers, nor much agreement as to what constitutes a river. Thus the River Ure and River Ouse can be counted as one river system or as two rivers. If it is counted as one, the River Aire/ River Ouse/Humber system would come fourth in the list, with a combined length of ; and the River Trent/Humber system would top the list with their combined length of .
