The five major lines of latitude are the Arctic Circle, the Tropic of Cancer, the Equator, the Tropic of Capricorn and the Antarctic Circle. Shortly thereafter, there were several attempts to make a clock that could accurately tell time on the unstable deck of a ship. It would be troublesome if people in one part of the world had no method of determining what time it was in another part of the world. To solve this problem, nations began standardizing time zones based, more or less, upon lines of longitude. Longitude (shown as a vertical line) is the angular distance, in degrees, minutes, and seconds, of a point east or west of the Prime (Greenwich) Meridian. These lines are known as meridians. Geography. A longitude system is also important for ocean navigation, as being able to track the passage of time across the various time zones is necessary for orientation.
