The Eastern Empire managed to divert the Visigoths into Italy, thus shoving the problem onto the Western Empire, which responded to this threat by pulling troops from the Rhine frontier. This triggered a pattern of events much like the cycle of anarchy in the third century C.E., only this time, no Aurelian or Diocletian emerged to save the Empire.
Because latitude runs from the equator to one or the other of the poles, 90 degrees. That's one-fourth of a full circle around the globe. Longitude starts at Greenwich, Englanâ¦d and runs, to the west or to the east, to the International Date Line (in the Pacific Ocean), 180 degrees.
By combining longitude and latitude measurements, any location on earth can be determined. The units of measurement for geographic coordinates are degrees (Â°), minutes ('), and seconds (). Like a circle, the Earth has 360 degrees. Each degree is divided into 60 minutes, which in turn is divided into 60 seconds. Latitude and longitude coordinates also include cardinal directions: north or south of the equator for latitude, and east or west of the prime meridian for longitude.
