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 Interval. Index contour intervals appear less frequently and represent a larger elevation change. It helps you figure out the amount of a large elevation difference faster because usually they are multiples of 100 or 1000, making them easier to add up.

The elevation change between two adjacent contour lines on a topographic map is known as the contour interval. This interval represents the difference in elevation between each contour line. For example, if the contour interval is 50 feet, it means that each contour line represents a change in elevation of 50 feet.
Contour interval.
The difference in elevation between two contour lines that are side by side is the contour interval. The contour interval is the vertical distance between two adjacent contour lines on a topographic map.
The elevation on a topographic map is shown using contour lines, which connect points of equal elevation. These contour lines help to visualize the shape of the land and provide information on the topography of the terrain. The spacing between contour lines indicates the steepness of the slope, with closer lines representing steeper terrain and wider spacing indicating flatter areas.
Contour lines connect points with the same elevation or value, showing the shape and elevation of the land on a map.
Contour lines show elevation on a topographical map. These lines connect points of equal elevation above sea level, with lines close together representing steep terrain and lines further apart indicating gentler slopes.
