Roxanne Lipsey:

Contour lines are drawn at specific intervals, such as every 10 feet, 20 feet or 30 feet. Each line represents a multiple of the scale chosen. Using the 10-foot scale as an example, each contour interval would represent a 10 feet change in elevation.

What is the difference between any two contour lines on a 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.


How do contour lines determine which area of an island has the steepest slope?

The closer the contour lines the steeper the slope.


What On topographic maps contour lines that are close together indicates?

The steeper the slope, the contour lines go further along the area. You can also determine the flatness of the area with these lines.


Why are contour interval on a topographic map of a mountainous area usually large?

Contour intervals on a topographic map of mountainous areas are usually large because the terrain is more rugged and the elevation changes are more pronounced. A larger contour interval helps to simplify the representation of complex topography and make the map easier to read and interpret.


What are contour intervals and contour lines?

Acontour line (also level set, isopleth, isoline, isogram or isarithm) of a function of two variables is a curve along which the function has a constant value.[1] In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level.[2] A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness of slopes.[3] The contour interval of a contour map is the difference in elevation between successive contour lines.[4] A contour interval is basically the same thing.


What is countour line interval?

It depends on the scale of the map, the range of values attained within the area of the map, the units of measurement and the accuracy of the contour data.


How do contuor lines help you to determine the area of an island has the steepest slope?

The area with the steepest slope is the area where the contour lines are bunched closest together.


What do contour lines on a topographic map show?

They show the relief of an area. They will have height values attached to them. The distance between contour lines gives an impression of gradient. The closer they are together, the steeper the slope.


How do you calculate the total relief on a topographic map?

To calculate the total relief on a topographic map, subtract the elevation of the lowest contour line from the elevation of the highest contour line within the map area. This difference represents the total vertical distance between the highest and lowest points on the map.


Why would a contour interval of 100 feet be better than a contour interval of 10 feet on a map of a mountainous area?

A contour interval of 100 feet would be more effective on a map of a mountainous area because it reduces visual clutter, making it easier to discern overall elevation changes and terrain features. In rugged landscapes, smaller intervals like 10 feet can create a complex and overwhelming map that obscures important landforms. The larger interval allows for a clearer representation of steep slopes and significant elevation differences, facilitating better understanding and navigation. Additionally, it can highlight major topographic features without getting lost in minor variations.
