Understanding Map Scales

This video tutorial covers the concept of scales in cartography, explaining how maps represent real-world sizes through ratio, verbal, and linear scales. It discusses the differences between large and small scale maps, and provides methods for measuring distances on maps using rulers and strings. The tutorial emphasizes the importance of choosing the right scale for different mapping purposes.

What is the primary purpose of using scales in cartography?

• To make maps look more colorful

• To represent objects on the map smaller than their real size

• To confuse the map readers

• To show the true size of objects

What does a ratio scale of 1:250 mean?

• 250 units on the map equals 1 unit in real life

• 1 unit on the map equals 250 units in real life

• 1 unit on the map equals 25 units in real life

• 250 units on the map equals 250 units in real life

Why might a scale of 1:25,000 be useful for a walk around a town?

• It shows a very large area with little detail

• It shows a small area with a lot of detail

• It is easier to carry

• It is more colorful

Which type of map shows more detail?

• Both show the same detail

• Small scale map

• Large scale map

• Neither show any detail

What is a verbal scale?

• A scale that uses colors to represent distances

• A scale that uses numbers only

• A scale that uses pictures

• A scale that uses a verbal description to relate map and real-world distances

How can you convert a verbal scale to a ratio scale?

• By dividing the stated distance by the length of the line

• By using a calculator

• By guessing the distance

• By measuring the map with a ruler

What is the first step in measuring the distance between two points on a map?

• Lining up a ruler between the points

• Estimating the distance

• Drawing a line between the points

• Using a piece of string

How do you convert centimeters to kilometers when measuring distances on a map?

• Divide by 100,000

• Divide by 1,000

• Multiply by 100,000

• Multiply by 1,000

What tool can be used to measure a curved distance on a map?

• A ruler

• A piece of string

• A compass

• A calculator

What is crucial to remember when measuring distances on a map?

• To use a colorful ruler

• Not to lose track of the zero point

• To use a verbal scale

• To measure only straight lines
