Chapter: 17. Globes And Maps

⁠

Question 1

The purpose of the scale bar is to show the relationship between a distance on the map and the corresponding actual distance on the ground. It helps us understand how much the real-world distance has been reduced to fit on the map.

Given the scale of 1 cm = 50 km, if the measured distance is 3 cm, the actual distance between Town A and Town B would be 3 cm * 50 km/cm = 150 km.

A scale is crucial for maps because it allows large areas of land to be represented accurately on a smaller surface. Without a scale, it would be impossible to determine the real-world distances between locations or compare the sizes of different geographical features shown on the map.

Question 2

The cardinal directions shown are North (N), South (S), East (E), and West (W).

The ordinal (intermediate) directions displayed are Northeast (NE), Northwest (NW), Southeast (SE), and Southwest (SW).

If North is at the top of the map, the direction directly to your right would be East (E).

Question 3

The blue colour in the central area of the map represents a water body, most commonly a lake, river, or ocean.

The brown colour typically symbolizes mountainous regions or highlands, indicating areas of high elevation. The green colour usually symbolizes lowlands or plains, representing flatter, lower-lying land.

Maps use a standardized system of colours to ensure clarity and easy understanding for anyone reading the map. This convention allows users to quickly identify different types of geographical features without needing a separate legend for every map, making map reading intuitive and efficient across various maps.
