What is the line of longitude used as the origin in a system of coordinates?

A longitude is a line that circles the globe from north to south. Longitudes are used to specify a location in degrees from east to west on the globe. See picture above. If the picture hasn't been changed the lines (not the equator) are longitudinal lines.

How are the lines of latitude and longitude used to locate points on Earth's surface?

The lines of latitude provide vertical (north-south) coordinates on a map or globe. Lines of longitude provide horizontal (east-west) coordinates. The defined geographical point is where the latitude line intersects the longitude line.


How do you use latitude and longitude coordinates to find an absolute location on a map?

First, look on the map to find the line of latitude that the coordinates reference. If the exact line of latitude isn't shown on the map, estimate it by looking at the lines that are available. Then look on the map to find the longitude line that the coordinates reference. Once you have found the two lines, follow them both towards the point where they intersect. That is the location the coordinates reference.


Is the equator is a main line of longitude?

The equator is the origin for the lines of latitude


What is the longitude latitude of the New Madrid fault line?

The New Madrid fault line is located in the central United States. Its approximate coordinates are 36.6°N latitude and 89.6°W longitude.


What are the coordinates along the central meridian?

Well, let's see . . . . . A "meridian" is a line of constant longitude, so wherever you are on it, the longitude is always the same number. Also, a meridian of longitude is a line that stretches all the way between the north pole and the south pole, covering all possible latitudes. So the coordinates on the central meridian are: (Any latitude you want), and (The same longitude everywhere on it).


What continents are crossed by the 15 degrees w longitude line?

Is Warsaw east or west of the 20 degrees east line of longitude?

Coordinates given in WikiPedia indicate a longitude of 21 degrees east. This puts the point at which this coordinate is set east of the 20 degree line.


What are the types of coordinate system?

There are two main types: Cartesian coordinates and Polar coordinates.In n-dimensional Cartesian coordinates there are n axes which are [usually] orthogonal and which meet at a single point called the origin. The coordinates of any point in the n-space are defined by the ordered n-tuple whose terms refer to the distances of the point, from the origin, along each of the axes.In n-dimensional Polar coordinates, the point is located using its distance from the origin and the angles that this radial line makes with specified lines and planes.


What is used to locate point in the plane?

Coordinates. These may be Cartesian - ie distance from the origin in mutually perpendicular (orthogonal) directions. Or they may be polar. Polar coordinates consists of the length of the line joining the point to the origin together with the angles that the line makes with the various principal planes (or hyperplanes).
