Longitude lines are the North/South lines that separate the earth in 15 degree sections. They are used for navigation.
"No-man's-land" because no one side controlled the area between the trench lines .
Longitude
Lines of longitude run north-south from pole to pole. They are an angular measure of how far east or west you are of the prime meridean which runs, north-south, through Greenwich, England.
Longitude and latitude are measured accurately using a system of imaginary lines on the Earth's surface. Longitude is measured in degrees east or west of the Prime Meridian, while latitude is measured in degrees north or south of the Equator. Special instruments like GPS devices and sextants are used to determine these coordinates with precision.

Peel an orange. The lines between the sections of the orange are similar to the pattern of longitude lines on the globe.
The Equator
Greece is in between 15 and 30 degrease East.......so that means it is about 20 degrease east in lines of longitude.

If you pick a longitude and mark a dot at every point on Earth with that longitude, the dots will form a line between the north and south poles. The imaginary line is called the "meridian" of that longitude.
grid lines of longitude and latitude
"Lines of longitude" are conceptual, not physical; there can be as many as we want. For example, there are 3600 "seconds of longitude" between each degree of longitude. That's 60 minutes of arc per degree, and 60 seconds of arc per minute.
Longitude lines are farthest apart at the equator, where the distance between them is about 69 miles (111 kilometers). As you move towards the poles, the longitude lines converge until they meet at the poles.
