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.

Is a contour interval for a given topographic map always the same?
A contour interval for a given topographic map always the same is true; not false.
What does a contour interval of 20 meters mean?
A contour interval shows a change in elevation on a topographical map. If the contour interval is 20 then the elevation change between two contour lines is 20 meters
What does a contour line measure?
The scale of contour lines on a topographic (terrain) map is called the "contour interval".
What is the contour interval for a topographic map of the volcano?
That depends on which Contour Map. The contour interval is the height difference between two adjacent contours on your map. The contours probably go up in 500 metre steps if it's a big volcano, so your contour interval is 500 metres.
What are the factors effecting contour intervals?
If the contour interval is not given, find two reference (labeled) contour lines and find the number of lines between them, excluding the reference lines themselves. Then the interval can be found using the following formula: |(Difference between elevation of reference lines)| /(Number of contour lines between reference lines +1) = Contour interval For example, if you find two reference lines labeled 150m and 250m and there is one contour line between them, then |150m-250m|/(1+1)=100m/2=50m The contour interval of that map is 50 meters.
What is the relationship between the relief of an area and the contour interval on a map of the area?
The Relationship between the relief of an area and the contour interval on a map of the area is A contour line
Is a contour interval for a given topographic map always the same?
A contour interval for a given topographic map always the same is true; not false.
The difference in elevation between the highest and lowest contour lines on a topographical map is called?
The difference in elevation between the highest and lowest contour lines on a topographical map is called a contour interval.
What does a contour interval of 20 meters mean?
A contour interval shows a change in elevation on a topographical map. If the contour interval is 20 then the elevation change between two contour lines is 20 meters
What does a contour line measure?
The scale of contour lines on a topographic (terrain) map is called the "contour interval".
How do you find the contour interval 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
What is the difference in elevation between two contour lines that are side by side?
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.
How does the relief of an area determining the contour interval used on a map?
?
On a topographic map the difference in elevation between one contour line and the next is the?
Contour interval
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?
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.
What is the contour interval for a topographic map of the volcano?
That depends on which Contour Map. The contour interval is the height difference between two adjacent contours on your map. The contours probably go up in 500 metre steps if it's a big volcano, so your contour interval is 500 metres.
