# Quick Answer: Can A Contour Line Split?

## Why do two contours never intersect each other?

Answer and Explanation: Contour lines never cross on a topographic map because each line represents the same elevation level of the land..

## What are the 3 types of contour lines?

There are 3 kinds of contour lines you’ll see on a map: intermediate, index, and supplementary.Index lines are the thickest contour lines and are usually labeled with a number at one point along the line. … Intermediate lines are the thinner, more common, lines between the index lines.More items…

## What is the space between contour lines called?

The space between the contour lines is called the contour interval and represents a specific (set) distance. If the contour interval is 50 feet, the vertical space between the two contour lines is 50 feet.

## What does it mean if contour lines are far apart?

Contour lines that are relatively close together indicate a slope that is fairly steep. Contour lines that are further apart indicates a slope that is relatively flat. The area of the map above boxed in orange shows an area that has a fairly steep slope, while the area boxed in purple is a relatively flat area.

## What are the rules for contour lines?

Rule 1 – every point of a contour line has the same elevation. Rule 2 – contour lines separate uphill from downhill. Rule 3 – contour lines do not touch or cross each other except at a cliff. Rule 4 – every 5th contour line is darker in color.

## Do all contour lines in the world eventually have to connect back to themselves?

There is no way that the line can stop until it runs back into its own tail. If students are having a hard time with this, consider making a contour map of your classroom, including the desks, to demonstrate how contour lines sometimes stack up, but always eventually close themselves.
