The difference in elevation between one contour line and the next is called relief. Hope this helped. ;)

contour interval
The size in the change of elevation from one contour line to another is called the contour interval. It represents the vertical distance between each contour line on a topographic map. The contour interval helps in understanding the slope and elevation changes of the terrain being represented.
Contour lines on a topographic map that are close together indicate a steep slope, while contour lines that are far apart indicate a gentle slope. If the contour lines form a V-shape pointing uphill, it indicates a valley, and if they form a V-shape pointing downhill, it indicates a ridge. The contour lines help users visualize the shape and steepness of the land surface.
The numbers on contour lines show the different elevations. Lets say one contour line says it has 1450 elevation. That means it is on the highest peak. When you see other numbers, that is just the elevation
Contour interval
The change in elevation from one contour line to the next is called the contour interval. It represents the difference in elevation between two adjacent contour lines on a topographic map.

The change in the elevation between isolines is called a contour line. Contour lines on a topographical map resemble a volcano.

latitude and longitude
contour interval. It represents the vertical distance between each contour line on the map. This interval is typically consistent across the map and can vary based on the scale of the map and the type of terrain being represented.
It depends completely on the type of map and the scale of the map. Look several contour lines above and below the area of interest. Often, the elevation is printed on every 5th contour line. Divide the difference by the number of spaces between the two lines. Example, one contour line says "1000" and the next one with an elevation says "1500". If there are 4 lines in between these two, it is 100 ft per contour line. In some areas, you will need to follow a contour line around the map to track down the elevation of that line. Easier still, check the legend on the side or bottom of the map. The example showing the colors or symbols used may also tell the contour interval if it is consistent for the entire map.
