They can't make a map unreliable unless they have been plotted inaccurately. Assuming correct measurement and plotting, as we normally can with a reputable map, the countours are within the measurement tolerance but can't show fine detail between them. Normally that does not matter of course because the natural land surface is irregular anyway within the general form traced by the contours.
Therefore the contours represent a smoothed plot of the slope; but they cannot be said to make the map unreliable.
The contour lines on a map indicate changes in elevation above sea level (or below, occasionally). The amount of change in elevation between lines is shown on the map legend, and will vary depending on the size of the map and the type of terrain.
The formula to calculate the contour interval of a map is the difference in elevation between two contour lines divided by the number of contour lines crossed. This provides the elevation change between each contour line on the map.
No, the contour interval can vary between different topographic maps based on the scale and detail of the map. Smaller scale maps may have larger contour intervals, while larger scale maps may have smaller contour intervals to show more detailed elevation changes.
A contour interval of 20 meters means that each contour line on the map represents a change in elevation of 20 meters. These contour lines help to visualize the shape and steepness of the terrain. The closer the contour lines are together, the steeper the terrain, while further apart lines indicate a gentler slope.
A topographic map of the Great Plains would typically have a small contour interval. This is because the region is relatively flat with subtle changes in elevation. A small contour interval helps to accurately depict these gradual elevation changes on the map.
Notice the pattern around that contour line. Then determine the interval that the surrounding contour lines are increasing or decreasing by. Ex. 50 100 150 200, the contour interval would then be 50
The Relationship between the relief of an area and the contour interval on a map of the area is A contour line
To find the contour interval on a topographic map, look for the difference in elevation between adjacent contour lines. The contour interval is usually given in the map's legend and represents the vertical distance between each contour line.
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.
The difference in elevation between the highest and lowest contour lines on a topographical map is called a contour interval.
A contour interval is the vertical distance between contour lines on a topographic map, representing the change in elevation. An index contour is a heavier contour line that is labeled with the elevation value, to help users quickly identify key elevations on the map.
The definition of a contour interval is the difference in elevation between two consecutive lines.
The contour lines on a map indicate changes in elevation above sea level (or below, occasionally). The amount of change in elevation between lines is shown on the map legend, and will vary depending on the size of the map and the type of terrain.
The formula to calculate the contour interval of a map is the difference in elevation between two contour lines divided by the number of contour lines crossed. This provides the elevation change between each contour line on the map.
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.

Contour lines on a map represent points of equal elevation. The difference in elevation between any two contour lines is called the contour interval, which is usually indicated on the map legend. By knowing the contour interval, you can determine the steepness of the terrain in that specific area.
