## Which statement about longitude and latitude is true? A. Latitude measures the distance from the

Degrees, minutes, and seconds are used to divide the earth's surface. For instance, as per the scope you can know whether you live in the Norh or the South of the Earth and how far you are from the Equator. Using the protractor, measure the smaller angle between the beam and the plumb line. If so, additional entries are made for use at night. It passes through Greenwich in southeast London, and is therefore sometimes referred to as the Greenwich Meridian. This means it is just under 30Â° north of the equator in latitude, and about 31Â° east of the prime meridian in longitude. Each degree of latitude is approximately 69 miles 111 kilometers apart.

Using Latitude and Longitude for Location 3. The position 5,3 is a unique location easily plotted on the cartesian plane. For the purpose of this discussion, assume a no-wind condition exists under which heading and course would coincide. Lines, or parallels, are drawn around the Earth at intervals. Eastern Standard Time, 11 a. Figure 16-5 shows the time zones in the conterminous United States.

## Lines of Longitude in Geography

This is the direction measured by reference to a meridian or true north. In the foreground is the explosion crater Viti and the larger lake Ã–skjuvatn, both formed in 1875. Keep in mind that you can also find the precise latitude and longitude of a location using a map application. Minor bends and turns in the isogonic and agonic lines are caused by unusual geological conditions affecting magnetic forces in these areas. One degree is equal to 60 minutes and 1 minute is equal to 60 seconds.

## Units of Longitude and Latitude

Since the Equator is a great circle, 1 o will subtend an arc of: 21640. The lines of longitude all converge at both poles, and are farthest apart from one another at the equator. Meridians and parallelsâ€”the basis of measuring time, distance, and direction. While the distance between degrees of latitude is constant 60 nautical miles or 111. This angle is your latitude.

## What do meridians measure

Because at the time in history when a system of navigational coordinates for the earth's surface was being developed, England was the dominant sea power, and England decided that the origin of longitude would be the meridian through the Royal Observatory in Greenwich. Unlike , there is no easy point of reference such as the equator to be designated as zero degrees in the longitude system. Today, longitude is more accurately measured with atomic clocks and satellites. When the sun is directly above the 90th meridian, it is noon Central Standard Time. Longitude is measured in both directions from the prime meridian. I promise I'm correct, because I got a 100% on this.

## Exercise 6. Calculating Distance Between Meridians of Longitude Along a Parallel of Latitude.

Because of the Earth's , the actual distance of a degrees, minutes, and seconds of longitude depends on its distance from the Equator. The longitude for Brasilia, Brazil, is 47Â° 55' W 47 degrees, 55 minutes west. All longitude on the earth is measured as so many degrees east or west of that meridian. This conversion is made by adding or subtracting the variation which is indicated by the nearest isogonic line on the chart. The longitude angle is measured from the center of the earth as shown in the earth graphic to the right. Longitude The demarcation of the longitude coordinate is done with lines going up and down are called the meridians.

## Do lines of longitude measure distance from east to west

Meridians are imaginary lines that run from North to South. On the west coast of the United States, the compass needle points to the east of true north; on the east coast, the compass needle points to the west of true north. The angular distance from the equator to the pole is one-fourth of a circle or 90Â°. They are denoted by the letters E or W to represent direction. At the Equator, the distance between meridians of longitude is 60 n. The equator and the poles are the most important parts of the earth's coordinate system.

## What Does Longitude Measure?

This unit is part of the. If you know how to read latitude and longitude on a map, you can determine the geographic coordinates of any spot on the map. The mathematical understanding needed for the course is not great. The Greenwich meridian begins in the north shaft goes through England and goes all te route toward the South Pole. The prime meridian runs through Greenwich, England. Longitude is related to , the measurement of distance north or south of the Equator.

## Latitude vs Longitude

Anyone who didn't like it â€¦ was free to take their ball and go home. Longitude is measured by imaginary lines that run around the Earth ly up and down and meet at the North and South Poles. It is noted by the meridians, lines drawn pole-to-pole. Explanation: a nonexistent line that partitions the world in two sides of the equator North and South , with the end goal to gauge the separation from this center point. This was inaccurate on long voyages out of sight of land and a solution to the problem of accurately calculating longitude eluded navigators for many centuries until John Harrison invented the chronometer in the 18th. Which statement about longitude and latitude is true? Latitude is your position north or south of the Equator. Its major limitation, however, is that it isn't visible from the southern hemisphere.

## How to Read Latitude and Longitude on a Map: 11 Steps

You can use a simple quadrant to measure latitude using either the sun or the North Star. To determine when it's noon without a watch or radio place a stick at the southernmost end of your north-south line. The Prime Meridian -- and its opposite, the International Date Line -- are lines of Longitude called meridians. There are 360 degrees of longitude because meridians make Great Circles around the globe , and there are 180 degrees of latitude. For the purpose of this discussion, assume a no-wind condition exists under which heading and course would coincide.
