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.
Degrees and Minutes The distance between degrees of longitude is about 60 nautical miles at the equator. It is less further north or south as the longitude lines converge towards the poles. Degrees of latitude are always 60 nautical miles apart. At the equator, a grid of 1Â° of longitude by 1Â° of latitude covers about 3,600 square miles. For greater precision, degrees are divided into 60 minutes ( ' ) - of distance, not time.
