They're labeled E (or W) to show that they're (E)ast or (W)est of the prime meridian (which is the line of longitude passing through Greenwich Observatory near London).
15 degrees East and 15 degrees West are the same distance from the prime meridian, but in opposite directions.
meridians or lines of longitude
longitude
The longitude lines cover the vertical side of the earth and the latitude lines cover the horizontal side. This gives you map coordination's.
In order to answer that question, I'd really have to see your globe, to know what things are labeled 'A' and 'B' . You did say that they're "lines", so I could guess that they're steamship lines, lines of constant latitude or longitude, international air routes, contours of constant elevation, etc. But there's no way to know without seeing them.
Every meridian of longitude is perpendicular to every parallel of latitude, and every parallel of latitude is perpendicular to every meridian of longitude.
E stands for east. Half of the longitude lines are east, the other half are w for west.
Because all of Australia is south of the equator and less than 180° east of the Prime Meridian.
E for East longitude.
Because you're only looking at 1/4 of the globe, or at a map of only part of the Earth. Go far enough north from where you're looking, and you're sure to find latitude lines that are labeled ' N '. Go far enough either east or west from where you're looking, and you're sure to find longitude lines that are labeled ' W '.
They're not. If 'S' and 'E' are the only labels you see, then you're only looking at 1/4 of the earth, or less. For every south latitude, there's also a north latitude with the same number, and for every east longitude, there's also a west longitude with the same number. You should turn your globe, or turn to another page in your book of maps. A whole new 3/4 of a world awaits you.

Longitude is labeled from zero (at the Prime Meridian) to 180 degreesin each direction, east and west, from it.
