Longitude and Latitude LO: to understand these terms and how they help us to find and describe different locations

Latitude and longitude 1 A system of lines is used to find the location of any place on the surface of the Earth. Lines of latitude run in an east-west direction. Lines of longitude run in a north-south direction.

Latitude Latitude (shown as a horizontal line) is measured in degrees north or degrees south of the equator, which is the line around the exact middle of the earth. Lines of latitude are often referred to as parallels. Arctic Circle (66° 30'' N) Antarctic Circle (66° 30'' S) Tropic of Cancer (23° 30'' N) Tropic of Capricorn (23° 30'' S) You may want to discuss minutes and seconds. Degrees of latitude and longitude can be divided into sixtieths, or minutes ('). Any location on Earth can be described as lying at a certain number of degrees and minutes of latitude either north or south of the equator and at a certain number of degrees and minutes of longitude either east or west of the prime meridian. For example, the United States Capitol in Washington D.C. is at 38 degrees 53 minutes north latitude (38° 53' N.) and 77 degrees 0 minutes west longitude (077° 00' W.). Minutes of latitude and longitude can be divided into sixtieths, or seconds ("), when more precise information on the location of a place is needed, for example, by navigators, surveyors, pilots, or map makers.

Latitude North Pole Equator South Pole

Longitude Longitude (shown as a vertical line) is measured in degrees east or west of something called the Prime Meridian. This is the line going from the North Pole to the South Pole and running through the middle of the Greenwich Observatory in London. Lines of longitude are often referred to as meridians. Prime Meridian You may want to discuss how longitude came to be calculated. The invention of clocks during the Renaissance was the first step toward the reliable calculation of longitude. The clocks of that era, however, were too inaccurate for use in navigation. In 1714 the British Board of Longitude offered a large cash prize to anyone who could build a clock that would meet certain standards of accuracy throughout long ocean voyages. By 1735 John Harrison, a British clockmaker, had submitted the first of several clocks, the last of which won the prize for him. They were called chronometers. In 1766 Pierre Le Roy, a Frenchman, built a chronometer more accurate than Harrison's. From that time on, sailors have been able to determine longitude accurately by comparing local time with Greenwich mean time (GMT). Shipboard chronometers are set to show GMT. Because of the speed and direction of the Earth's rotation, local time at a given place will be one hour behind GMT for every 15 degrees west of the prime meridian and one hour ahead of GMT for every 15 degrees east of the prime meridian. For example, if a ship's chronometer reads 0300 (3:00 AM) and the ship's local time is 0800 (8:00 AM), the ship is 75 degrees east of Greenwich, or at 75° E. Special radio time signals allow navigators to check the accuracy of their chronometers.

Why is the Prime Meridian in Greenwich? Britain was a world leader in exploration and map making. Therefore, navigators of other nations often used British maps. As a result, in 1884 the meridian of Greenwich was adopted throughout most of the world as the Prime Meridian.

Simple Rules Latitude is shown by horizontal lines going around the earth from the North to the South Pole. Longitude shows how far east or west something is from a line called the Greenwich Meridian. Co-ordinates must have the latitude followed by the longitude. Eg. (20˚S, 20˚W)
