## What is the difference in elevation between two consecutive contour lines known as?

Untitled Document.

The difference in elevation between successive contour lines on a given map is fixed.

This vertical distance between any two contour lines in a map is called the contour interval (C.I.) of the map..

## What is the elevation of the lowest index contour line?

500 metersThe lower index contour line is numbered 500, which means any point on that line is at an elevation of 500 meters above mean sea level. The upper index contour line is numbered 600, or 600 meters.

## Can a contour line on a topographic map connect a point with an elevation of 100 feet to a point with an elevation of 110 feet?

Can a contour line on a topographic map connect a point with an elevation of 100 feet to a point with an elevation of 110 feet? Explain why or why not. No, because a contour line connects points of equal elevation. The elevation of 100 feet as to equal 100 feet , which 110 feet is a different number and height.

## What are the 5 Rules of 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.

## Why do contour lines never cross?

Contour lines can never cross one another. Each line represents a separate elevation, and you can’t have two different elevations at the same point.

## What does Index contour mean?

Index contours are bold or thicker lines that appear at every fifth contour line. If the numbers associated with specific contour lines are increasing, the elevation of the terrain is also increasing.

## How do you find the difference in elevation between index contours?

To find the elevation interval between the contour lines, Divide the difference in elevation between the index lines by the number of contour lines from one index line to the next. In the example above, the distance 200 is divided by the number of lines, 5.

## Do Contour lines connect points of equal elevation?

A contour line connects points of equal height above sea level, called elevation. For example, a 600′ (six hundred foot) contour line on a map means that every point on that contour line is 600′ above sea level.

## What 2 types of lines show elevation differences?

Contour lines are used to show elevation on a topographic map. Lines or isolines on a map that connect points with the same elevation. What does each contour line on a map show? Each contour line shows a different elevation.

## What are 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.

## How do index contours let you know if the land you are viewing is increasing or decreasing in elevation?

Answer Expert Verified. Index Contours are indicated by a thicker line compared to the others. Index Contours are labelled with specific elevations along it to give a better understanding of the scale of elevation.
