No, but you're on the right track. A meridian of longitude is only half of a circle, Read more: Are_all_lines_of_longitude_great_circles Technically, No, but you're on the right track. A meridian of longitude is only half of a circle, because it joins the north and south poles. But the circle that it's a half of is indeed a 'great' one, because its center is at the Earth's center.

What else can I help you with?
Do the longitude lines meet at the north and south pole?
By definition, a line of longitude is an imaginary great circle on the surface of the earth passing through the north and south poles at right angles to the equator such that "all points on the same meridian have the same longitude".Therefore, all lines of longitude meet at a point at each of the poles.
Why are the equator and all lines of longitude called great circles?
The equator and all lines of longitude are called great circles because the represent the circumference of the earth. The other latitude lines along the globe are smaller then the actually circumference.
When you move away from the equator where do meridians go?
Meridians converge at the poles and intersect the equator at 90 degrees. They are all great circle lines called lines of longitude. The equator is a line of latitude and the only line of latitude that is a great circle line. As you move away from the equator the lines of latitude describe smaller and smaller circles round the planet as you approach the poles.
Do all meridians converge at the poles?
By definition, a line of longitude is an imaginary great circle on the surface of the earth passing through the north and south poles at right angles to the equator such that "all points on the same meridian have the same longitude".Therefore, all lines of longitude meet at a point at each of the poles.
Which is true about lines of longitude?
Every meridian of constant longitude is nominally a semi-circle, equal in length to all other meridians, and joining the Earth's north and south poles.
At what point of earth do all lines of longitude meet?
All lines of longitude meet at the North and South Poles.
Why are the lines of longitudes equal?
Lines of longitude converge at the poles. They are all great circles that intersect at the North and South Poles and are equidistant from each other. This convergence creates lines of longitude that are all equal in length.
Do eastern or western lines of longitude run through great plains region?
The ones in the USA and Argentina are all at west longitudes, and I wouldn't be at all surprised to learn that there are some even greater plains in Russia, at eastern longitudes.
At what longitude does the Arctic Circle lie?
All of them.
Are the Arctic Circle 23 degrees south and the Equator lines of latitude or longitude?
First of all, the Arctic Circle is the one at roughly 23.5 degrees North.It ... along with the equator, the Antarctic Circle, and the Tropics of Cancerand Capricorn ... are all parallels of constant latitude.
Why all meridians of longitude are semi-great-circles?
-- Each meridian joins the north and south poles, making it a semi-circle. -- The center of the circle of which it is a semi is at the center of the Earth, making it a 'great' one. Among parallels of latitude, only the equator is a great circle.
How are the lines of latitude and longitude alike?
A few similarities include:-- Both are sets of imaginary lines. You may be standing exactly on one, ordriving, sailing or flying over it, but you see no line there.-- Both are loci (locuses) of constant angles. One is a locus of constant latitude,the other is a locus of constant longitude.-- Both are markers of angles corresponding to the familiar, ordinary, everydaypolar coordinate system.-- Both are almost universally misunderstood.-- There is no limit to the number of either set. There are potentially an infinite numberof longitude lines, since a line may be drawn at any longitude. And there are potentiallyan infinite number of latitude lines, since a line may be drawn at any latitude.-- Every member of one set intersects ALL of the members of the other set.-- Both may or may not be printed on any given globe or map. It's the publisher's choice.-- When they are printed on a map or globe, the interval between lines is also completelyup to the publisher.A few differences include:-- All longitude lines intersect, but no latitude lines intersect.-- Latitude lines are complete circles, but longitude lines are semi-circles.-- Latitude lines are all parallel, but no two longitude lines are parallel.-- All longitude lines are 1/2 of a great circle of the Earth, but only one latitude line(the equator) is a great circle of the Earth.-- All longitude lines are the same length, but for each latitude line, there is onlyone other that has the same length.-- Longitude lines are all centered on the Earth's center, but latitude lines are allcentered somewhere on the Earth's axis.
