Contour lines are used in maps to show the elevation and shape of the land. They connect points of equal elevation and help visualize the terrain's features such as hills, valleys, and slopes. By closely spaced contour lines, you can tell steep terrain, while widely spaced ones indicate flat areas.
Index contour lines are thicker and usually have their elevation labeled. They help users quickly identify key elevations on a topographic map. In contrast, regular contour lines show the shape and elevation of the land but do not have specific labels.
The definition of a contour interval is the difference in elevation between two consecutive lines.
On a topographic map, contour lines that are closer together indicate a steeper slope.
The name for the elevation difference between adjacent contour lines is the contour interval.
Maps can show elevation with contour lines
The darker contour lines on map are called index contour lines. Numbers that indicate elevations are often written on these lines.
Contour intervals are used to represent changes in elevation on a topographic map. The interval is the difference in elevation between adjacent contour lines. By looking at the contour lines, you can visualize the shape of the land, such as steep slopes, valleys, or hills.
Hachured contour lines are contour lines with ticks pointing downslope that indicate a depression on a topographic map.
A contour map. The lines are called contour lines
Cartographers use contour lines to show the elevation of landforms on maps. These lines connect points of equal elevation, allowing viewers to visualize the shape and steepness of the terrain. The spacing and pattern of contour lines provide valuable information about the topography of an area.

Contour lines that are evenly spaced and parallel indicate a plateau. The closer the contour lines are to each other, the steeper the terrain; the farther apart they are, the flatter the land. In the case of a plateau, contour lines would likely be spaced evenly and relatively close together, indicating a flat or gently sloping landform.
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 definition of a contour interval is the difference in elevation between two consecutive lines.
The main topographic map rules include contour lines never crossing, contour lines close together represent steep terrain, contour lines spread out represent flat terrain, and elevation is indicated by the contour lines.
