The document discusses the three main types of scales used on maps: direct statement, representative fraction, and linear scale. Direct statement uses words to represent the scale, such as 1cm equals 1km. Representative fraction uses a ratio, like 1:100,000, to show the scale. Linear scale divides the map with a line that can be measured with a ruler to determine the scale. The document also explains that large scale maps, like 1:50,000, show details of a small area, while small scale maps, like 1:5,000,000, show larger areas with less detail.

- 2. 3- TYPES SCALE .1- DIRECT STATEMENT .2-REPRESENTATIVE FRACTION .3- LINEAR SCALE
- 3. DIRECT STATEMENT written words 1cm to 1km/1cm represents 1km This means that 1cm on the map represents 1km on the earth’s surface
- 4. REPRESENTATIVE FRACTION written in numbers as a ratio 1:100 000 or 1/100 000 -This means that 1cm on the map represents 1km on the earth’s surface
- 5. LINEAR SCALE divided line. Use a ruler to measure linear scale. You will see that 1cm represents 1km on the earth’s surface.
- 6. LARGE OR SMALL MAPS Large scale maps- scale of 1:1 000 000 or larger 1:250 000, 1:50 000, 1:10 000) -show a small area of the earth in considerable detail -usually topographic maps Small scale maps- scale of 1:1 000 000 or smaller 1:5 000 000, 1:8 000 000) -show relatively large areas of earth in not so much detail
