What is the difference between "latitude" and latitude line?"

Latitude is how far N a point is from the equator. Latitude line is that latitude extended all the round the Earth.

Here's what I posted for you a few minutes ago.

Latitude lines go around the globe -- east-west -- and are parallel to each other. They measure distance from the Prime Meridian.

Longitude lines go up and down (the long way) -- north-south. They are not parellel to each other, but meet at the Poles. They measure distance from the Equator.

Surely the other way about?

"Latitude" refers to the measurement of distance, in degrees, north or south of the equator. It helps to specify a location's position relative to the Earth's equator. On the other hand, a "latitude line" is an imaginary line drawn on maps or globes that represents a specific latitude measurement.

To understand the difference between the two, let's consider how to determine the latitude of a location using a latitude line.

1. Start by identifying the equator, which is the horizontal circle around the Earth's middle at 0 degrees latitude.
2. Using the equator as a reference point, measure the distance in degrees north or south to the desired location.
3. A latitude line is then drawn on the map or globe to represent this specific measurement.
4. Latitude lines are usually evenly spaced and parallel to the equator, extending from 90 degrees north (the North Pole) to 90 degrees south (the South Pole).
5. Each latitude line is assigned a specific value in degrees, such as 30 degrees north or 45 degrees south.

In summary, "latitude" is the measurement of distance north or south of the equator, while a "latitude line" is an imaginary line drawn on a map or globe to represent a specific latitude measurement.
