Question 7.
Name the two types of maps based on scale.
Answer:
Small Scale Maps
When large areas are shown on a small map, it is called small scale map.
- These maps give very limited information.
- The map of India is a small scale map.
Large Scale Maps
- When small areas are shown on large map it is called Large scale map.
- These maps give detailed information.
- The map of Delhi, shown on large sheet of paper is a large scale map.
Question 8.
How are directions known?
Answer:
Directions are known by the following:
Maps contain an arrow marked with the letter ‘N’ on the upper right.
An Arrow with ‘N’ mark:
- This arrow shows the North direction.
- It is called north line. On the Earth one can find out directions e.g. north, east, west and south.
- There are four major directions.
- North, South, East, West. They are called cardinal points.
- Other four intermediate directions are North-East (NE), South-East (SE), South¬West (SW) and North-West (NW).
- One can locate any place more accurately with the help of these intermediate directions.
Compass. One can also know the direction with the help of compass
- It is an instrument used to find the main directions.
Maps Class 6 Extra Questions Long Answer Type
Question 1.
How is distance measured? Define a scale.
Answer:
Maps reduce the entire world or its part to fit on a sheet of paper.
But this reduction is done very carefully so that distances between the places are kept true:
- Reduction of map is only possible when small distances on paper represents a large distance on the ground.
- To reduce a map, a scale is chosen.
Scale is the ratio between the actual distance on the ground and the distance shown on the map.
- The distance between school and home of student is 10 km. If he shows this 10 km distance by 2 cm on map, it means, 1 cm on the map will show 5 km on ground. Thus the scale will be 1 cm. = 5 km. In this way scale is very important in a map. If the scale is known it will be easy to calculate distance between any two places.
- Scales are used for measuring distance. For example to find out the distance between the post office and the clock tower one can measure the distance between these points on the map. (Then the same distance on the scale. Types of Maps on the Basic of Scale.)
Question 2.
What are symbols? Why do we need them?
Answer:
Symbols:
It is impossible to draw actual shape and size of different features like buildings, roads, trees, railway lines or a well on a map, so we use various symbols to show these features.
- Symbols give much information in a limited space.
- With the help of these symbols, we can draw maps and read them easily.
- Without knowing the language of a certain place, we can collect information from maps with the help of these symbols.
- Maps have a universal language – a language that can be read by all. An international agreement facilitates the use of these symbols.
- These symbols are called Conventional Symbols.
- Some of the conventional symbols are shown in the figure given below.
- Various colours in maps are also used for the same purpose.
