Contour lines can never touch each other, and they can never just stop, they have tonot go off the page or connect.
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 contour interval between two contour lines marked 10m and 20m is the difference in elevation between the two lines. In this case, the contour interval is 20m - 10m = 10m. Therefore, the contour interval is 10 meters.
Because contour lines make places of equal height.
The definition of a contour interval is the difference in elevation between two consecutive lines.
The name for the elevation between two adjacent contour lines is known as the contour interval. It represents the difference in elevation between each contour line 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.
Contour interval.
Contour line's measure elevation, there cannot be a space with two different elevations at the same time. For example, a hill can be 1,000 feet tall at the summit but not also 5 ft at its summit (unless you're in some parallel dimension). So no, they never cross.
the elevation difference between two adjacent contour lines.
the contour interval
One contour can not cross another because a contour is one exact elevation; if it crossed another contour it would show that it is higher than the second contour on one side, but lower on the other side.
The elevation difference between two side-by-side contour lines is known as the contour interval. It represents the vertical distance in elevation between each contour line on a topographic map.
