One way to describe the size of something is to compare it with the size of something else.
Example:o That lemon is the size of a softball.o The battle ship is the length of two football fields.

Because maps cover large regions, we use a scale to determine the distance between two places.
![Page 6: Scale](https://reader035.fdocuments.in/reader035/viewer/2022070404/56813add550346895da3276a/html5/thumbnails/6.jpg)
The measured distance between two points is called physical distance.

Calculating Distance Using Scale
You’ll need a text book - page 19 – and a piece of paper
![Page 8: Scale](https://reader035.fdocuments.in/reader035/viewer/2022070404/56813add550346895da3276a/html5/thumbnails/8.jpg)

Construct a paper ruler:1. Place a strip of paper along
the scale line.2. Make a pencil mark at the 0,
100 km and 200 km points.3. Place the 200 km mark you have just made at
0 on the line scale and mark off another 200 km in 100 km intervals.
4. Continue making marks until your ruler is long enough.
5. Be sure to label your marks!

o Lines of longitude are used to mark time zones.
![Page 30: Scale](https://reader035.fdocuments.in/reader035/viewer/2022070404/56813add550346895da3276a/html5/thumbnails/30.jpg)
o Each time zone is 15° wide, the distance the sun travels in one hour.
![Page 31: Scale](https://reader035.fdocuments.in/reader035/viewer/2022070404/56813add550346895da3276a/html5/thumbnails/31.jpg)
o The Prime Meridian, which passes through Greenwich, England, is the 0° longitude location or starting point where time zones are measured east and west of that line.
The Prime Meridian – the starting line for time zones

o Time zones to the East of the Prime Meridian are one hour ahead, and time zones to the West of the Prime Meridian are one hour behind.

As we travel west over the IDL, it is one day later.
As we travel east over this line, we “gain a day."

o A time zone map tells you the time in different parts of the word. Canada has a total of six time zones:
