10 Questions
What is a scale map?
A scale map is a map that contains a scale, which is a ratio of two numbers.
How do you read a scale ratio?
You read a scale ratio as '1 to 18,000', meaning one of something on the map is equal to 18,000 of that same thing in the real world.
What is the purpose of a scale map?
The purpose of a scale map is to show the relationship between distances on the map and the actual distances in the real world.
What is a bar scale?
A bar scale is a line on some maps that shows a specific distance on that map.
How can you convert inches on a scale map to feet in real life?
You can divide the number of inches on the map by 12 to convert it to feet in real life.
What is the purpose of using a scale map?
The purpose of using a scale map is to accurately represent distances and measurements of real-life objects or locations on a smaller, more manageable map.
How can you convert feet to inches?
To convert feet to inches, you need to multiply the number of feet by 12, as there are 12 inches in a foot.
What is the scale of the map created in the example?
The scale of the map created in the example is 1:4,800.
What are the four steps to create a scale map?
The four steps to create a scale map are: 1) Find a map of the area you want to use. 2) Find the actual and measured distances of two points on the map. 3) Divide the actual distance by the measured distance on the map to determine the scale. 4) Place the scale numbers on the map.
What are some examples of objects that can be used as measuring tools on a scale map?
Examples of objects that can be used as measuring tools on a scale map include pens, shoelaces, and hands.
Study Notes
How Scale Maps Work
- A scale map is a map that contains a scale, which is a ratio of two numbers.
- The scale is typically written in the corner of the map and is read as "1 to X", where X is the corresponding number.
- The scale ratio is used to determine the actual distance between two points on the map.
Understanding Scale
- The scale ratio is used to convert measurements on the map to actual measurements in real life.
- For example, if the scale is 1:18,000, one inch on the map is equal to 18,000 inches in real life.
- This can be converted to more manageable units, such as feet, by dividing by 12 (since there are 12 inches in a foot).
Measuring with Scale Maps
- The scale map allows you to measure distances using any object, such as a pen or a finger.
- The measurement must be consistent, and the scale ratio is used to convert the measurement to the actual distance.
- For example, if the distance between two points on the map is equal to the length of your pinkie finger, the actual distance would be 18,000 of your pinkies lined up end-to-end.
Creating a Scale Map
- To create a scale map, follow these four steps:
- Find a map of an area you want to use.
- Find both the actual and measured distances of two points on your map.
- Divide the actual distance by the measured distance on the map to find the scale.
- Place the scale numbers on the map.
- The scale ratio is a ratio of two numbers, and it can be used to convert measurements on the map to actual measurements in real life.
