grid lines of longitude and latitude
The meridian 20° west of The Greenwich Observatory, London, England. It is a line of longitude that runs from the north pole to the south pole. So you would look along the 20° west line of longitude. You also need a line of latitude. Minutes and seconds is then used to find a precise spot on the earth.
That meridian has no special name. If it's shown at all on a map or globe, it'll be labeled "60".
Longitude lines show the number of degrees east and west of the Prime Meridian. They are farthest apart at the equator and converge to a single dot at the north and south poles. Latitude lines show distance north and south from the equator. Because they are parallel to the equator, they never converge. Latitude at 90o north and south can be shown only as a dot, not a line.
That's like asking "How many inches difference is between the marks on the ruler ?". The answer is: It depends on the ruler. They're not all the same, and there's no official standard set of marks. Some globes have lines every 15 degrees, some have lines every 20 degrees, or every 30 degrees, or every 10 degrees, and some have no lines printed on them at all.
Altitude is height above the ground. Latitude and Longitude are map coordinates. Lines of Latitude are the horizontal lines shown running east-to-west on maps and locate your position on the globe in the North-South direction.
grid lines of longitude and latitude
Latitude is the distance of a point north or south of the equator in degrees, minutes, and seconds. Latitude lines on a globe are parallel lines circling the planet north and south of the equator.Longitude is the distance of a point east or west of the Prime (Greenwich) Meridian in degrees, minutes, and seconds. Longitude lines are shown on a globe as regularly spaced vertical lines between the north and south poles.

Latitude
Lines of latitude and longitude are only shown only maps so as to help people navigate and pinpoint places on Earth with more accuracy.
Latitude and longitude are expressed in terms of angle measure.They are measurements, referring to the angle of any point on earth, [east or west] of the Prime Meridian,and [north or south] of the equator.They're not divided into anything.The lines you see on a map or globe are not the only ones that exist, only a few shown for convenience.Similarly, the lines on a ruler or measuring tape are obviously not the only possible measurements.
First you go to where the prime meridian (0 degrees line of longitude) and the equator (0 degrees line of latitiude) cross, which is just south of Ghana in Africa. From there you go east or west according to the first coordinate and follow that around the earth to the correct line of longitude. Then you go north or south from that point to whatever the latitude indicates. The lines are usually shown on the globe at 15 degree intervals so you will need to interpolate (approximate) the position between the lines.

The key is the part that tells you what is shown on the globe.

The parallels of latitude and the meridians of longitude are all straight lines on the Mercator projection. That's why Greenland looks bigger than South America.
