Each of those lines is a meridian of longitude. They are 180 degrees apart in longitude,
so together they form a complete circle around the Earth. That circle is the boundary
between the eastern and western hemispheres.

Longitude are the lines east and west of the Prime Meridian.

The Prime Meridian is the 0° longitude line, running though Greenwich, England.

It is 0 degrees longitude. If you move east the longitude increases and if you move west the longitude decreases.

Is the Tropic of cancer a line of latitude or a line of longitude?

The Tropic of Cancer is a parallel of latitude, roughly 23.5 degrees north of the equator.


How do you calculate longitude on a map?

Latitude and longitude go together to make the address of a point on the Earth's surface. You can't calculate them, any more than you can calculate the address of a house on the map. If there are some lines on the map that show the locations of a few latitudes and longitudes, then maybe you can estimate the coordinates of a point on the map by referring to the lines.


What is latitude closely related to?

It is closely related to the Greenwich meridian.


Are all the lines of latitude the same length?

no they are notThe lines of latitude run East/West. Each line forms a circle around the earth. The equator is at latitude zero degrees, and it encircles the earth. As we travel further and further North the earth, being a globe shape, gets narrower and narrower the further North we go. So all the circles get smaller and smaller as we move from the equator to the North. The lines of latitude are parallel to each other.Montreal, in Canada, is about 45o latitude, that is, halfway between the equator and the North pole, so a horizontal circle at that point would be smaller than the circle of latitude at the equator.At 80o North, the circle of latitude at that angle from the equator is just a small circle around the North pole. At 890 degrees North it is nearly at the North pole and the circle is very small. The North pole itself is at a latitude (angle) of 900, and there is no circle at all! It's smaller than a dot!The lines of longitude run from the North pole to the South pole. All the lines run from the top of the earth to the bottom of the earth. The lines converge at the poles, and are widest at the equator. Unlike the lines of latitude, all lines of longitude are the same length.For more information, see 'Related Links' below.


What is one degree of latitude equal to in nautical miles?

The lines of longitude radiate out from the poles. At their point of origin, i.e. at 90o latitude, there is no distance at all between the lines! However, at latitude 89o, very near the poles, the distance between the respective 'one degree' lines of longitude is about one nautical mile. At latitude 48.37o the distance along the line of latitude is 40 nautical miles And a 1o longitude difference along the equator (0o latitude) represents a distance of about 60.1 nautical miles.

How are latitude and longitude related?

Latitude gives the angle, and therefore the distance from, the equator, which is a north to south distance. Longitude gives the angle, and therefore the distance, from the arbitrary Prime Meridian, thus defining locations by their distances east to west. Latitude lines, such as the equator, run horizontally on maps. Longitude lins, such as the International Date line, run vertically.

What is longitude means?

longitude: distance east or west on the earth's surface, measured in degrees from a certain meridian. (line from the North to the South Pole.)Or you can check out this website it has a lot on geography:See related link below

How are latitude and climate related?

latitude is one of the four factors that affect climate. lines of latitude may be farther or closer to the equator, which determines the climate. for example, if the lines of latitude are farther from the equator, the climate will be colder than if the latitude is closer to the equator.
