No,it is a line of latitude
is it the equator
'Lines' of longitude are called "meridians".The equator is not one of them.
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.
The line of longitude that Magellan's fleet crossed into the Pacific Ocean was the equator. The other line of longitude crossed was the Tropic of Capricorn.
The equator is the origin for the lines of latitude
The equator is defined as the zero reference line of latitude.
The Equator is a longitude line. Latitude lines pass through the equator.
All lines of longitude pass through the Equator.
All of the meridians of longitude cross the equator.
