The Genetic Control Of Organ Shape – What Can The Fruit Fly Teach Us? Longitude is a similar measurement east or west of … The lines of latitude run 90 degrees north and south, so check the N or S after the coordinates to see which hemisphere it is in. For example, 30°E, the line passing through eastern Africa, is an angular distance of 30° east of the Prime Meridian. Some time zones even have offsets of only half an hour or 45 minutes. Without these measurements, Global Positioning Systems wouldn’t work. (spelling counts) by mskaon Plays Quiz not verified by Sporcle . 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. Longitude. The Equator, middle of the globe, is at 0 degrees latitude. Draw a diagram showing all the five major lines of latitudes. Want more Science Trends? Beautifully written. The lines from pole to pole are lines of constant longitude, or meridians. The "E" indicates that it is that distance east of the Prime Meridian. Meridians converge at the poles and are farthest apart at the equator (about 69 miles (111 km) apart). 23 1/2 degrees N latitude. You need to add a day to your calendar if you cross the Date Line while going east to west, and you need to subtract a day if you cross it going west to east. Like parallels, meridians name the specific line and indicate the distance east or west of a 0° line. The problem with this is the fact that variables like altitude impact sunrise and sunset, leading to a situation where cities located on roughly the same lines of latitude had different times. These lines are known as meridians. You’ve probably heard of latitude and longitude before. The longitude system is necessary because we have to have a standardized way of tracking the passage of time across the globe. Get an answer to your question "What are the 2 major lines of longitude? Absolute Location, Major Lines of Lat and Long, and Cont DRAFT. The longitude coordinates are given after the latitude coordinates, with “W” representing points west of the Prime Meridian leading up to 180 degrees and “E” representing points east of the Prime Meridian, also leading up to 180 degrees. Lines of longitude run from the top of the Earth to the bottom. Every line of longitude also crosses the equator. In the early 1600s, a new idea to measure longitude was developed when Galileo determined that it could be measured with two clocks. Running in the opposite direction, north-south, the prime meridian is one of the most important lines of longitude on Earth. They are so accurate that they can locate cities and even buildings to within inches. Advertisement.
