The lines are relatively useless. But the angle of longitude itself is of interest, because time according to the sun advances through longitude at a steady rate, moving through 1 degree every 4 minutes, or 15 degrees every hour.

There's another way of saying this.
The earth revolves once every 24 hours. There are 360o in a circle. Suppose you were in able to remain motionless above the equator, so that the earth could rotate beneath you, and that you were holding a watch. Every hour the earth would rotate through 360o/24=15o.
This means that if you started watching the time just as you pass over the zero longitude you would see the 15o longitude at one hour, the 30o longitude at two hours, the 45o at three hours, and so on, until the saw the 360o longitude at the end of a full 24 hours-back where you started.

Are latitude lines used to determine time zones?

What are lines of longitude and which ways do they run?

What is the highest longitude lines?
The highest longitude lines are the prime meridian at 0 degrees longitude and the 180 degrees longitude line. These lines mark the starting point for longitude measurements to the east and west, respectively.

What do you call the vertical lines around the globe?
meridians or lines of longitude

What is characterized as vertical imaginary lines on the Earth's surface?
Lines of longitude, or meridians.
What do longitude lines have to do with time?
There are 24 time zones. The Earth is 360 degrees around the circumference. So, for every 15 degrees of longitude there is one time zone.
Why are the lines of longitude not parallel?
Parallel lines, by definition, cannot meet. The lines of longitude meet at the Poles.
