Longitude is the angular distance of a place east or west of the Greenwich meridian, or west of the standard meridian of a celestial object, usually expressed in degrees and minutes.
The Polynesians developed the fine art of navigation by stars, inherited from the early arab navigators. Arabians used hand measures to measure the height of the star above the horizon to determine their latitude according to the angle determined.
Answer:
<u>Time is measured in Lunar month </u>
Explanation:
- The lunar month is the time the moon takes to pass through each phase i.e new moon to half and then to the full moon etc. Taking about 29 days, 12 hours, 44 minutes and 3 seconds to complete this rotation on its axis.
- Thus the moon only takes 27.3 days to complete this action. Thus as the moon goes back in its orbit it takes 2.2 days to catch up. Moon also has the same elliptical longitude as that of the sun as seen from the earth's surface.
- The motion of the moon is in an eastward direction along with the motion of stars, thus it shows the same face to earth every day. This is evident as it moves just 13 degrees in 24 hours.
