NCERT Class 6 Geography Chapter 4 Extra Questions
1. What is a map?
Answer: A map is a drawing of the Earth’s surface or part of the Earth on a flat surface. A map can be drawn for a village, city, state, country, or the full earth.
2. How is a map better than a globe?
Answer: A map is more informative than a globe. It is easy to carry. A map is more useful when we want to study part of the Earth.
3. What is an atlas?
Answer: An atlas is a collection of various types of maps. Atlases can have various sizes, measurements, and map scales.
4. What are the types of maps?
Physical Maps: Maps showing natural features of the earth such as mountains, plateaus, plains, rivers, oceans, etc. are called physical or relief maps.
Political Maps: Maps showing cities, towns, and villages, and different countries and states of the world with their boundaries are called political maps.
Thematic Maps: Maps containing specific information on various themes are called thematic maps. For example, road maps, rainfall maps, maps of forests, industries, etc.
5. Why do we use a scale on a map?
Answer: To make a map of a place or the full Earth on paper, we have to reduce their sizes to fit them on paper. So, we have to reduce the size very carefully so that the distance between the places is real. Map scales are used to provide information on the reduction of size.
6. What is a ratio scale?
Answer: Ratio scale is the ratio of the distance on a map to the actual distance on the ground.
For example, if 2 cm represents 500 km on a map then we can show the ratio scale in two ways.
Ratio Scale = 2 cm/500 km
Ratio scale = 2 cm : 500 km)
7. In how many ways can we show a map scale?
Answer: Map scale can be shown in three ways:
(1) Linear Scale
(2) Ratio Scale
(3) Verbal Scale
8. What are the types of a map scales?
Answer: There are two types of a map scale:
(1) Small scale map
(2) Large scale map
9. What is the difference between a small-scale map and a large-scale map?
A small-scale map is used when a map is drawn for larger areas. A large actual distance is represented by a distance on the map.
Example: 2 cm = 500 km
Large scale map is used when a map is drawn for smaller areas. A smaller actual distance is represented by a distance on the map.
Example: 2 cm = 500 m
10. How do we use direction on a map?
Answer: Generally North direction is shown pointing towards the top of the map. Maps are made in such a way that the North direction points towards the top.
11. What are the types of directions?
Answer: There are two types of directions:
(1) Cardinal Directions (North, East, South, West)
(2) Ordinal or Intermediate Directions (NW, NE, SE, SW)
12. How are symbols useful on maps?
Answer: Actual shape and size of different features such as buildings, roads, bridges, trees, railway lines, etc. can not be shown on a map. So, they are shown by symbols (letters, shades, colors, pictures, lines, etc.). These symbols give a lot of information in a limited space.
13. What is a conventional symbol?
Answer: To make a map readable by everyone, there is an international agreement to use some common symbols. The symbols that have the same meaning throughout the world are called conventional symbols.
14. What do various colors represent on a map?
Answer: Various colors are used to make the maps more informative.
Generally blue is used for showing water bodies, brown for mountains, yellow for a plateau, and green is used for plains.
15. What is the difference between a sketch and a plan?
|The sketch is a rough drawing without a scale.||A Plan is a detailed drawing of a small area on a large scale.|
|The sketch is a memory-based drawing just to indicate various places.||Detailed information like lengths, widths, etc. is shown in plans.|
Convert the following Verbal Scales to Ratio Scale and Linear Scale.
(a) 5 cm on a map represents 400 km on the ground.
Ratio Scale = 5 cm : 400 km
(b) 2 cm on a map represents 250 km on the ground.
Ratio Scale = 2 cm : 250 km
(c) 3 cm on a map represents 600 m on the ground.
Ratio Scale = 3 cm / 600 m
(d) 2 cm on a map represents 1500 m on the ground.
Ratio Scale = 2 cm / 1500 m
(e) 1 cm on a map represents 100 km on the ground.
Ratio Scale = 1 cm / 100 km
Convert the following Linear Scales to Ratio Scale and Verbal Scale.
Ratio Scale = 8 cm / 4000 miles
or Ratio Scale = 1 cm / 500 miles
Ratio Scale = 4 cm / 760 km
or Ratio Scale = 1 cm / 190 km
