(c) What do you understand by the scale of a map?
Answer:
- The scale of a map means the ratio between the actual distance on the ground and the distance shown on the map.
- Map scales are used to represent large areas of the Earth on small paper.
(d) How are maps more helpful than a globe?
Answer.
- We use the globe when we have to study the whole earth but when we want to study some part of the earth like country, state, region or village, continent, any ocean then the map is more useful.
- Globe does not give us much information about an area whereas a map gives more accurate and comprehensive information than the globe.
For the above reasons, we can say that maps are more helpful than globes.
(e) Distinguish between a map and a plan.
Answer:
- In the map, we outline large areas using a small scale( using the scaling down method), for example, in the map, we show the continents by making them smaller.
- Whereas in the plan, we outline the small area on a large scale, for example, we make the plan, not the map for building a house which contains specific information about the length and width of the room.
- As much information as is available in the plan, we are not able to give or get it on the map.
(f) Which map provides detailed information?
Answer:
- When we show a village, city, or small area on a map, we use a large scale because we need detailed information about the particular area.
- For example, We may use 100 meters distance between sites in 5 cm in the map, this type of map is called a large-scale map. The large-scale map provides detailed information.
(g) How do symbols help in reading maps?
Answer:
- The symbol is one of the three components of the map.
- We will not be able to represent the actual size of various geographical features like buildings, trees, mountains, cities, etc on the map. Symbols help to depict this information in a limited space.
- Symbols are a universal language that makes maps understandable to all.
