When looking at a map. latitude lines run horizontally. Latitude lines are besides known as analogues since they are parallel and are an equal distant from each other. Each grade of latitude is about sixty-nine stat mis ( 111 kilometer ) apart ; there is a fluctuation due to the fact that the Earth is non a perfect domain but an pumpkin-shaped ellipsoid ( somewhat egg-shaped ) . To retrieve latitude. conceive of them as the horizontal rounds of a ladder ( “ladder-tude” ) . Degrees latitude are numbered from 0° to 90° North and South. Zero degrees is the equator. the fanciful line which divides our planet into the northern and southern hemispheres. 90° North is the North Pole and 90° South is the South Pole.
The perpendicular longitude lines are besides known as acmes. They converge at the poles and are widest at the equator ( about 69 stat mis or 111 kilometers apart ) . Zero grades longitude is located at Greenwich. England ( 0° ) . The grades continue 180° E and 180° west where they run into and organize the International Date Line in the Pacific Ocean. Greenwich. the site of the British Royal Greenwich Observatory. was established as the site of the premier acme by an international conference in 1884.
How Latitude and Longitude Work Together
To exactly turn up points on the earth’s surface. grades longitude and latitude have been divided into proceedingss ( ‘ ) and seconds ( “ ) . There are 60 proceedingss in each grade. Each minute is divided into 60 seconds. Seconds can be farther divided into ten percents. hundredths. or even thousandths. For illustration. the U. S. Capitol is located at 38°53’23?N. 77°00’27?W ( 38 grades. 53 proceedingss. and 23 seconds north of the equator and 77 grades. no proceedingss and 27 seconds West of the meridian passing through Greenwich. England ) .
