There is no particular name for that event. It was decided long ago that since every
parallel of latitude crosses each of the infinite number of meridians, and that every
meridian of longitude crosses each of the infinite number of latitudes, it would be
cruel to expect students, even gifted ones, to learn all of those names.
Any line of longitude (or of latitude, for that matter), that crosses the United States, will divide it in two.
All lines of longitude are equal. The longest line of latitude is the Equator.
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.
Zero longitude is the prime meridian. Zero latitude is the Equator.
-- The place where a latitude intersects a longitude is a point, not a line. -- There are an infinite number of different longitudes, and each latitude intersects all of them. -- There are an infinite number of different latitudes, and each longitude intersects all of them. -- So you can see that there are a truly huge number of intersections. In fact, every point on Earth is an intersection of one latitude and one longitude, and no two points on Earth are the same intersection. On account of all that, there are no names.
No "named" line of longitude crosses Australia. The Tropic of Capricorn (latitude) crosses Australia.
No "named" line of longitude crosses Australia. The Tropic of Capricorn (latitude) crosses Australia.
Any line of longitude (or of latitude, for that matter), that crosses the United States, will divide it in two.
The Tropic of Capricorn crosses every meridian of longitude on the face of the earth, but no latitudes.
A line of constant longitude is often called a "meridian". A line of constant latitude is often called a "parallel".
Each line of latitude (the ones parallel to the Equator) crosses each line of longitude (the north - south lines).
The Antarctic Circle is a line of latitude -- which moves, according to the Earth's wobble. As of 10 March 2016, it runs 66°33′46.1″ as a line of latitude and crosses all degrees of E and W longitude on Earth.
Each 'meridian' is a line of constant longitude.
-- All lines of longitude meet at the north and south poles. -- No two lines of latitude ever meet or cross each other. -- Every line of longitude crosses every line of latitude. -- Every line of latitude crosses every line of longitude. -- There are an infinite number of each kind, so there are an infinite number of places where a line of longitude crosses a line of latitude. (That's kind of the whole idea of the system.)
The equator is a latitude line, so it has no specific longitude. The equator is at 0o north or south. There are many points on the equator, so every point on the equator has a different longitude.
"Crossing the Line" is associated with crossing the equator at 0 degrees latitude, not longitude. If you cross the equator (0 degrees latitude) at 0 or 180 degrees longitude, there is an additional status included.
You mean latitude and longitude?
