An index contour is a thicker contour line that is labeled with the elevation of that contour. It usually appears every fifth contour line and helps to quickly identify elevation changes on a topographic map. Regular contour lines are thinner and connect points of equal elevation.

What are the difference's between contour interval and index contour?
A contour interval is the vertical distance between contour lines on a topographic map, representing the change in elevation. An index contour is a heavier contour line that is labeled with the elevation value, to help users quickly identify key elevations on the map.
What is the difference between a contour interval and an index contour?
A contour interval is the vertical distance between two contour lines on a map, representing the change in elevation. An index contour is a thicker contour line labeled with the elevation of the line above sea level, typically every fifth contour line. It helps users quickly identify elevation values on a map.
How does index contour lines differ from other contour lines?
Index contour lines are thicker and usually have their elevation labeled. They help users quickly identify key elevations on a topographic map. In contrast, regular contour lines show the shape and elevation of the land but do not have specific labels.
How far apart would two successive index contours be on a map with a contour interval of 5 meters?
Two successive index contours would be 10 meters apart on a map with a contour interval of 5 meters. This means that each index contour line represents a change in elevation of 10 meters from the next adjacent line.
How can index contours be identified?
Index contours on a topographic map can be identified by looking for thicker contour lines compared to the surrounding lines. They are typically labeled with their elevation value. Index contours are used to provide a quick reference to the elevation changes on the map.

An index contour is a thicker contour line labeled with the elevation of the line above sea level, typically every fifth contour line. It helps users quickly identify elevation values on a map.
On a topographic map where would you locate the contour interval in the margin?
It would be the difference between the two darker lines, or index lines, and then divide the space in between with your difference.
What is difference in elevation between two successive index contours on a map with a contour interval of 5 m?
The difference in elevation between two successive index contours on a map with a contour interval of 5 meters is exactly 5 meters. Index contours are typically marked with heavier lines and are used to indicate elevation at specific intervals, in this case, every 5 meters. Therefore, each standard contour line between the index contours represents a change in elevation of 5 meters as well.
What is every fifth contour line?
it is a contour line of elevation Control index contour, or just index contour
How does index contour lines differ from other contour lines?
Index contour lines are thicker and usually have their elevation labeled. They help users quickly identify key elevations on a topographic map. In contrast, regular contour lines show the shape and elevation of the land but do not have specific labels.
What is the elevation change between two adjacent lines on a map?
Those lines representing elevation on a map are called contour lines. The difference in elevation between two of these lines is called the contour interval. Different maps use different contour intervals based on the scale of the map, or in other words, the size of the contour interval is based on how zoomed in and detailed the map is. Sometimes a map will have darker and thicker contour intervals. This is called the Index Contour Interval. Index contour intervals appear less frequently and represent a larger elevation change. It helps you figure out the amount of a large elevation difference faster because usually they are multiples of 100 or 1000, making them easier to add up.
How is an index contour usally indicated?
An index contour is typically indicated on a topographic map by a bold line, often labeled with its elevation in feet or meters. These lines are usually spaced at regular intervals, such as every 100 or 500 feet, and help to provide a clear reference for understanding the terrain's elevation changes. In addition to the index contours, intermediate contours may be shown as lighter, thinner lines between the index contours.

What is the 5th contour line called?
An Index Contour
What is a index contour?
A thicker line that has numbers written on it showing the rising or decreasing elevation on a topographic map By Ash Every fifth contour line on a topographic map, usually thicker, used to label elevation.
What is a darker contour line usually every fifth line?
It makes it easier to count the number of contour lines.
