What part of a map tells the relationship of distance shown on the map to real distance on the Earth?
Map scale
The part of a map that tells the relationship of distance shown on the map to real distance on the Earth is called the scale.
To identify the scale on a map, you can look for a graphic representation of a line or a bar with labeled distances. This line or bar is divided into increments that represent a certain measurement, such as miles or kilometers. By measuring a distance on the map using the scale, you can determine the equivalent real distance on the Earth's surface.
Here's how you can use the scale to calculate distances:
1. Locate the scale on the map. It is typically found in a corner or along the edges.
2. Identify the units of measurement used on the scale (e.g., miles, kilometers).
3. Measure the desired distance on the map using a ruler or another measuring tool.
4. Align the ruler with the scale on the map and determine the real distance by observing the corresponding measurement on the scale.
For example, let's say the scale on a map indicates that 1 inch represents 10 miles. If you measure a distance of 3 inches between two points on the map, you can calculate that the real distance between those points is 30 miles.
Remember, it's important to use the scale accurately to ensure accurate measurements when working with maps.
