# What is the name for the elevation difference between two adjacent contour lines?

Contour interval

### What is the elevation change between two adjacent lines on a map?

Those lines representing elevation on a map are called contour lines. The difference in elevation between two of these lines is called the contour interval. Different maps use different contour intervals based on the scale of the map, or in other words, the size of the contour interval is based on how zoomed in and detailed the map is. Sometimes a map will have darker and thicker contour intervals. This is called the Index Contour…

### How can contour lines demonstrate the levels of elevation on a map?

Each contour line represents a certain elevation, and the difference in elevation between any two adjacent countour lines is constant. So, for example, if in the map area there were a cone-shaped feature, like a volcano, the shape would be shown as a circle in a circle in a circle in a circle (and so on). The more contour lines you cross along a path, the steeper the climb, and the fewer contour lines you…
