If the time at village A (long 75°W) is 5:00pm on Friday. Solutionĭestination time = Initial time + calculated time Calculate the time that Mary will arrive at her destination. Mary starts her journey at longitude 0° and she’s moving towards eastward of longitude 10°. top↑ Longitude Calculations ProceduresĬ] Convert the longitude difference to time and,ĭ] Adjust the time according to the direction of movement, ( west or east). The Earth rotates from west to east, so every 15° towards the east, the local time advanced by 1 hour, and every 15° from east towards the west, the local time retard by 1 hour. top↑ Longitude And Timeĭuring Rotation And Revolution of the earth, the earth passes through 360° in 24 hours, 15° in 1 hour or 1° in 4 minutes.
top↑ĥ] latitude has many great circle while longitude has only one circle.Ħ] latitude has the equator as its reference point while longitude has the Greenwich meridian as its great circle.ħ] Latitudes can only be measure from 0° to 180° while longitude can be measured from 0° to 360°.Ĩ] lines of latitude are not used to calculate local time while lines of longitude are used to calculate local time.ĩ] lines of latitude are use to measure distance while lines of longitude are not use to measure distance.ġ0] lines of latitude do not meet at the pole while lines of longitude meet at the pole. top↑ Difference Between The Lines Of Latitudes And Lines Of Longitudesġ] lines of latitude run from west to east while lines of longitude run from north to south.Ģ] Lines of latitude are shorter towards the pole while lines of longitude are of the same length.ģ] lines of latitude are parallel to each other while lines of longitude are not parallel to each other.Ĥ] lines of latitude are called parallel while lines of longitude are called meridian. top↑ Lines Of Latitudes And Lines Of Longitudes Similarities Between Lines Of Latitudes And Lines Of Longitudesġ] Both are imaginary lines drawn on the globe.ģ] They are both used to determine the location of places on the map.ĥ] They are both used to calculate distance and measurement. Important Of Lines Of Longitudeġ] The lines of longitude along with the lines of latitude are used to determine the exact location of a place on the atlas map.įor example, Nigeria is located between longitude 3☎ and 15☎ of the Greenwich meridian.Ģ] The lines of longitude are used to determine local time in relation to G.M.T which means Greenwich Mean Time, which is sometimes referred to as world time. Important lines on Longitude are 0°, Longitude 180W and longitude 180☎, etc – Longitude Definition And Calculations. The longitude passing through Britain(London) and Accra (Ghana) is called the great prime or Greenwich meridian and it is inclined at longitude 0°. Longitude of a place, is an angular distance of east or west of the Greenwich meridian measured at the center of the earth, there are 180° of east longitude and 180° of west longitude.
Meridian : are line, at right angle parallel through the poles.
