equator and hemisphere
Two of them.
They cross at the two poles.
Latitude and longitude
Yes.
Any two lines of longitude you choose get closer togetheras they proceed from the equator to the poles.
Every point on Earth has a latitude and a longitude. No two points have the same set of two numbers.
The two tropics are lines of latitude at 23°26′13.0″ North and South of the Equator and they intersect all lines of longitude.
Greece is in between 15 and 30 degrease East.......so that means it is about 20 degrease east in lines of longitude.
meridians or lines of longitude
Just like parallel lines on a flat surface, no two parallels of latitude ever meet.Just like non-parallel lines on a flat surface, any two meridians of longitude do meet.In fact, ALL meridians of longitude meet, at both the north and the south poles.

Lines of latitude run round the earth parallel to the Equator. Lines of longitude run from pole to pole, crossing the Equator at 90 degrees.
