state the two forms of map scale
Answers
Answer:
There are two main types of map scales: bar and lexical. In a bar scale, which tends to be the most common, the mapmaker has given you a visual guide to use to make distance calculations. You can use any measuring tool or a piece of string to figure out actual distances on a map by directly measuring the map distance and translating it to the bar scale.
A lexical scale is not visual like a bar scale. Instead, the mapmaker gives the distance conversion in words. For example, the map may include the scale written as '1 inch equals 10 miles'. This is generally viewed as less practical and is, therefore, much less common. With this scale, it is also much more common to run into language barriers for speakers of languages other than what the map is written in. This scale works in the same way as the bar scale, but it is just represented differently.
