Refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground. On a 1:100,000 scale map, 1cm on the map equals 1km on the ground. Whether the scale is drawn out or written, you can easily calculate distances if you know the ratio.

Relation between distance, corresponding distance on the map, and corresponding distance on the ground
The correct answer to this question is option 'B', which is 'Scale'. The scale is a representation of the relationship between distances on a map and the corresponding distances on the ground. It is an essential element of a map that helps users understand the true size and distance of objects or locations.
Understanding Scale
Scale is usually presented on a map as a line or bar that is labeled with a unit of measurement, such as kilometers or miles. This line represents a specific distance on the ground, and it is divided into smaller segments that correspond to specific distances on the map. By using the scale, one can measure distances on the map and convert them into real-world distances.
Types of Scale
There are two types of scales commonly used on maps:
1. Representative Fraction (RF) Scale: This type of scale is expressed as a ratio or fraction. For example, a scale of 1:50,000 means that one unit on the map represents 50,000 of the same units on the ground. This scale is often used on topographic maps and architectural plans.
2. Graphic Scale: This type of scale is represented by a line or bar that is marked with distances. The length of the line corresponds to a specific distance on the ground, and it is divided into smaller segments that represent smaller distances. This scale is commonly found on road maps and tourist maps.
Importance of Scale
The scale is crucial for interpreting and using maps accurately. It allows users to measure distances, estimate travel times, and plan routes. Without a scale, a map would be meaningless as it would not provide any information about the actual size or distance of the depicted features.
Conclusion
In conclusion, the relation between the distance on a map, the corresponding distance on the ground, and the scale is an essential concept in cartography. The scale provides a means to convert map distances into real-world distances, enabling users to understand and navigate the map accurately.
